Centuries ago, all scientists were interdisciplinary. we can learn from that approach today..
A few years ago, I gave a talk at a university’s physics department about my “alternative” career. I was the editor for a physics magazine, and I frequently got requests to explain how — and why — I left active research.
After the talk, my host leaned on the podium and, with eyebrow raised, said, “So, you traded depth for breadth?” He was right: I was happier knowing a bit about many topics than a lot about just one. Seeing the connections between research — from the impossibly fine precision of nanotechnology to the mysteries of dark matter — made me feel closer to science, and it was one of the reasons I left what had become an overly specialized science career.
I’m sharing this story because it explains why I find interdisciplinary research so attractive. Whether you think of it as applying the tools of one field to understand another, or discovering problems that only live at the boundaries of different fields, there’s a need to think broadly, see a problem from multiple angles, and collaborate. You can’t get locked into a narrow view. Instead, diverse scientific perspectives need to work seamlessly together.
The challenges facing us are too complex to solve with a single viewpoint. Look, for example, at the National Academy of Engineering’s “Grand Challenges” list : making solar energy economical, advancing health informatics, developing carbon sequestration methods, and more. Not a single one could be solved within one discipline. One of the biggest research funding agencies in the U.S. — the National Science Foundation — prioritizes interdisciplinary work , noting that “support of interdisciplinary research and education is essential for accelerating scientific discovery and preparing a workforce that addresses scientific challenges in innovative ways.”
Specialized, field-specific research is, of course, still essential. Without that specialist focus, we wouldn’t have the knowledge base to tackle big problems. The ideal interdisciplinary team of the future will need to have a mixture of these specialists and researchers who can build connections between them. That connector-builder is a special skill because you need to speak the languages of many fields and ask questions that pull people into new ways of thinking.
Another reason to champion interdisciplinary research is that it can prepare students for fulfilling careers in various sectors of the workforce. Interdisciplinary research is inherently relatable, and that simple fact can be a compelling reason to choose science as a profession. Returning to the grand challenges list, you see things like making better medicines, understanding the brain, or improving how we learn. These are problems that matter to humans, and solving them can be a fulfilling career.
And careers in various sectors are increasingly valuing interpersonal skills like communication, collaboration, and team building. In recent years, close to a third of U.S. physics Ph.D.s who remained in the U.S. went into the private sector within a year of earning their doctorates. Large fractions of Ph.D.s in other science and engineering fields are finding jobs in the private sector as well. Working within an interdisciplinary team trains you to think broadly and collaboratively — desirable skills wherever you work, and especially valued in the private sector. Encouraging those skills through interdisciplinary projects at the graduate school level allows universities to better prepare their students for their careers.
I love physics because it trains you to simplify complicated problems to their essence. That simplifying mindset is an asset. But the joke about physicists is that they sometimes take the simplification too far — using a sphere to model a porcupine. Meaningful approaches to solving a problem require the expertise of environmentalists, biologists, doctors, engineers, and so on to know where that simplifying is okay and where it’s not. For a physicist, that means learning not only a new language but even a new mindset about how to add detail to theory.
We see that intersection occurring at the interface between physics and biology. Traditional areas of physics — like mechanics, collective motion, complexity, statistical physics, and fluid dynamics — are merging with fundamental questions in biology, like cell migration, cell motility, epidemiology, and population dynamics. Universities and research labs are creating centers to support interdisciplinary work. At the American Physical Society, we launched a new journal, PRX Life , in 2023 to feature exactly that kind of research.
Another interdisciplinary avenue is the intersection of materials discovery with artificial intelligence. Researchers have nosed around for new materials for decades, using theory and intuition to identify the right blend and arrangement of atomic elements. They then painstakingly tweak the recipe. That approach led to high-temperature superconductors and the materials used in airplanes and lightweight batteries. Today, AI is able to predict hundreds of thousands of new materials at once — a scale far beyond what humans were able to do before. The people who predict and search for materials must work with those who know how to design and train these AI tools to fully take advantage of this new technology.
Finding research outside of your specialty isn’t necessarily hard, but you have to make the time to look. One tip is to skip your department colloquium every once in a while for a seminar in another area. Science journalists also offer a lot of great stuff to read. The APS online magazine, Physics , makes a point of highlighting interdisciplinary research for its readers. All of the articles are free, and there’s a mixture of easy reading and more in-depth analysis of new results.
Published research is easier to find now that more of it is available in open-access journals, which don’t require a subscription to read. Two journals from APS — Physical Review X and Physical Review Research — offer exclusively open-access studies that cover all of physics and research that physics touches. Anyone can check out the cool stuff that editors have labeled “interdisciplinary physics” in PRX . The list includes new approaches to understanding cancer cells, climate, and animal behavior.
A thousand years ago, all scientists were interdisciplinary. Now, we’re in a new era where specialists need to diversify. There’s inertia to doing that because it means moving out of your comfort zone and often learning a new language and way of thinking. That’s the challenge — and appeal — of working in any diverse group.

Title: perspectives from physics graduate students on their experiences in nsf research experiences for undergraduates.
Abstract: National Science Foundation (NSF) funded Research Experiences for Undergraduates (REUs) are explicitly intended to reach minoritized students in STEM and those who have few research opportunities. Many undergraduates are encouraged to seek them out, but their actual efficacy is not well-established, and the out-of-state travel required for many attendees may prove a significant barrier for the very students REUs wish to reach. We interviewed physics graduate students who attended REUs as undergrauates, focusing on how the REUs benefitted them, barriers they faced attending REUs, and their relationship with their REU mentors. Interviewees reported benefits that aligned with the NSF goals: skills, enculturation, and knowledge they had not received in their undergraduate institutions. They also reported financial barriers they faced which they were able to overcome due to their financial privilege. Participants also reported widely varying experiences with their mentors. Some mentors did and some did not meet their mentees where they were at in their career and skill levels. Some students did not know how to approach their mentors with their questions or needs.

On the first day of her class, Annika Martin asks the assembled researchers at the University of Zurich in Switzerland to roll out their yoga mats and stand with their feet spread wide apart. They place their hands on their hips before swinging their torsos down towards the mat and back up again. The pose, called ‘wild goose drinking water’ is from Lu Jong, a foundational practice in Tantrayana Buddhism.
Martin, a health psychologist, can sense that some students are sceptical. They are academics at heart, many of whom have never tried yoga, and registered for Martin’s course to learn how to deal with the stress associated with academic research. Over the course of a semester, she teaches her students about stress and its impact on the body before giving them the tools to help cope with it — from yoga, meditation and progressive muscle relaxation to journalling.
It is one of many initiatives designed to combat the mental-health crisis that is gripping science and academia more broadly. The problems are particularly acute for students and early-career researchers, who are often paid meagre wages, have to uproot their lives every few years and have few long-term job prospects. But senior researchers face immense pressure as well. Many academics also experience harassment, discrimination , bullying and even sexual assault . The end result is that students and academics are much more likely to experience depression and anxiety than is the general population.
But some universities and institutions are starting to fight back in creative ways.
The University of Zurich now offers academics several popular courses on mental health. Beyond Martin’s class, called ‘Mindfulness and Meditation’, one helps students learn how to build resilience and another provides senior researchers with the tools they need to supervise PhD candidates.
The courses are in high demand. “We have way more registrations than we have actual course spots,” says Eric Alms, a programme manager who is responsible for many of the mental-health courses at the University of Zurich. “I’m happy that my courses are so successful. On the other hand, it’s a sign of troubling times when these are the most popular courses.”
Several studies over the past few years have collectively surveyed tens of thousands of researchers and have documented the scope and consequences of science’s mental-health crisis.
In 2020, the biomedical research funder Wellcome in London, surveyed more than 4,000 researchers (mostly in the United Kingdom) and found that 70% felt stressed on the average work day . Specifically, survey respondents said that they felt intense pressure to publish — so much so that they work 50–60 hours per week, or more. And they do so for little pay, without a sense of a secure future. Only 41% of mid-career and 31% of early-career researchers said that they were satisfied with their career prospects in research.

A survey designed by Cactus Communications , a science-communication and technology company headquartered in Mumbai, India, analysed the opinions of 13,000 researchers in more than 160 countries in 2020 and found that 37% of scientists experienced discrimination, harassment or bullying in their work environment. This was especially true for researchers from under-represented groups and was the case for 42% of female researchers, 45% of homosexual researchers and 60% of multiracial researchers.
Yet some experts are hopeful that there is change afoot. As well as the University of Zurich, several other institutions have started to offer courses on mental health. Imperial College London, for example, conducts more than two dozen courses, workshops and short webinars on topics as diverse as menstrual health and seasonal depression. Most of these have been running for at least five years, but several were developed in response to the COVID-19 pandemic. “At that time, the true dimension of the mental-health crisis in science was unveiled and potentially exacerbated by the lockdowns,” says Ines Perpetuo, a research-development consultant for postdocs and fellows at Imperial College London.
Desiree Dickerson, a clinical psychologist with a PhD in neuroscience who leads workshops at the University of Zurich, Imperial College London and other institutes around the world, says she has a heavier workload than ever before. “Before COVID, this kind of stuff wasn’t really in the spotlight,” she says. “Now it feels like it is gaining a solid foothold — that we are moving in the right direction.”
A mental-health crisis is gripping science — toxic research culture is to blame
Some of this change has been initiated by graduate students and postdocs. When Yaniv Yacoby was a graduate student in computer science at Harvard University in Cambridge, Massachusetts, for example, he designed a course to teach the “hidden curriculum of the PhD”. The goal was to help students to learn how to succeed in science (often by breaking down preconceived ideas), while creating an inclusive and supportive community. An adapted form of that course is now offered by both Cornell University in Ithaca, New York, and the University of Washington in Seattle. And Yacoby has worked with other universities to develop single-session workshops to jump-start mental-health advocacy and normalize conversations about it in academia.
Similarly, Jessica Noviello, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, built a workshop series designed to target a key stressor for academics’ mental health: job insecurity, or specifically, the ability to find a job that aligns with career plans and life goals. She argues that most advisers lack experience outside academia, “making it hard for them to advise students about other career options”, and most institutes don’t have the resources to bring in outside speakers. Yet it is a key issue. The 2020 Wellcome survey found that nearly half of the respondents who had left research reported difficulty in finding a job.
So Noviello established the Professional Advancement Workshop Series (PAWS) in August 2021. The programme has run workshops and panel discussions about careers at national laboratories and in science journalism and media communications, science policy, data science, NASA management and more. And it has hosted two sessions on mental-health topics. “PAWS isn’t a programme that specifically set out to improve mental health in the sciences, but by building a community and having conversations with each other, the experts, and ourselves, I think we are giving ourselves tools to make choices that benefit us, and that is where mental health begins,” Noviello says.
Although these courses and workshops mark a welcome change, say researchers, many wonder whether they are enough.
Melanie Anne-Atkins, a clinical psychologist and the associate director of student experience at the University of Guelph in Canada, who gives talks on mental health at various universities, says that she rarely sees universities follow through after her workshops. “People are moved to tears,” she says. “But priorities happen afterward. And even though they made a plan, it never rises to that. Because dollars will always come first.”
David Trang, a planetary geologist based in Honolulu, Hawaii, at the Space Science Institute, is currently working towards a licence in mental-health counselling to promote a healthier work environment in the sciences. He agrees with Anne-Atkins — arguing that even individual researchers have little incentive to make broad changes. “Caring about mental health, caring about diversity, equity and inclusion is not going to help scientists with their progress in science,” he says. Although they might worry about these matters tremendously, Trang argues, mental-health efforts won’t help scientists to win a grant or receive tenure. “At the end of the day, they have to care about their own survival in science.”
Still, others argue that these workshops are a natural and crucial first step — that people need to de-stigmatize these topics before moving forward. “It is quite a big challenge,” Perpetuo says. “But you have to understand what’s under your control. You can control your well-being, your reactions to things and you can influence what’s around you.”

That is especially pertinent to the typical scientist who tends to see their work as a calling and not just a job, argues Nina Effenberger, who is studying computer science at the University of Tübingen in Germany. The Wellcome survey found that scientists are often driven by their own passion — making failure deeply personal. But a solid mental-health toolkit (one that includes the skills taught in many of the new workshops) will help them to separate their work from their identity and understand that a grant denial or a paper rejection is not the end of their career. Nor should it have any bearing on their self-worth, Effenberger argues. It is simply a part of a career in science.
Moreover, Dickerson argues that although systemic change is necessary, individuals will drive much of that change. “My sense is that if I can empower the individual, then that individual can also push back,” she says.
Many researchers are starting to do just that through efforts aimed at improving working conditions for early-career researchers, an area of widespread concern. The Cactus survey found that 38% of researchers were dissatisfied with their financial situation. And another survey of 3,500 graduate students by the US National Science Foundation in 2020 (see go.nature.com/3xbokbk) found that more than one-quarter of the respondents experienced food insecurity, housing insecurity or both.
In the United States, efforts to organize unions have won salary increases and other benefits, such as childcare assistance, at the University of California in 2022, Columbia University in New York City in 2023 and the University of Washington in 2023. These wins are part of a surge in union formation. Last year alone, 26 unions representing nearly 50,000 graduate students, postdocs and researchers, formed in the United States.
There has also been collective action in other countries. In 2022, for example, graduate students ran a survey on their finances, and ultimately won an increase in pay at the International Max Planck Research School for Intelligent Systems (IMPRS-IS), an interdisciplinary doctoral programme within the Max Planck Society in Munich, Germany.
Why the mental cost of a STEM career can be too high for women and people of colour
Union drives are only part of the changes that are happening beyond the classroom. In the past few years, Imperial College London has revamped its common rooms, lecture halls and other spaces to create more places in which students can congregate. “If they have a space where they can go and chat, it is more conducive to research conversations and even just personal connection, which is one of the key aspects of fostering mental health,” Perpetuo says. Imperial also introduced both one-day and three-day voluntary retreats for postdocs and fellows to build personal relationships.
The IMPRS-IS similarly runs ‘bootcamps’ or retreats for many of its doctoral students and faculty members. Dickerson spoke at the one last year. The programme also mandates annual check-ins at which students can discuss group dynamics and raise any issues with staff. It has initiated thesis advisory committees so that no single academic supervisor has too much power over a student. And it plans to survey its students’ mental health twice a year for the next three years to probe the mental health of the institute. The institute has even set various mental-health goals, such as high job satisfaction among PhD students regardless of gender.
Dickerson applauds this change. “One of the biggest problems that I see is a fear of measuring the problem,” she says. “Many don’t want to ask the questions and I think those that do should be championed because I think without measuring it, we can’t show that we are actually changing anything.”
She hopes that other universities will follow suit and provide researchers with the resources that they need to improve conditions. Last year, for example, Trang surveyed the planetary-science community and found that imposter syndrome and feeling unappreciated were large issues — giving him a focus for many future workshops. “We’re moving slowly to make changes,” he says. “But I’m glad we are finally turning the corner from ‘if there is a problem’ to ‘let’s start solving the problem.’”

While half the global population relies on rice as a staple, about 15% of rice produced each year is contaminated by potentially fatal aflatoxins. Seeing this threaten lives in her home country of Kenya prompted a graduate research assistant to focus on eradicating the risk through safer storage methods.
Faith Ouma, a Ph.D. student in the food science department at the University of Arkansas, was the lead author of " Investigating safe storage conditions to mitigate aflatoxin contamination in rice ." It was published in the journal Food Control .
Ouma completed her undergraduate studies in biochemistry in Kenya before earning a master's and pursuing a doctoral degree at the University of Arkansas. Her study was conducted through the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture. The food science department is part of the Dale Bumpers College of Agricultural, Food and Life Sciences.
When exposed to poor storage conditions such as high temperatures and humidity, rice can become contaminated with fungi. Fungi can then produce naturally occurring toxic compounds called mycotoxins though researchers have yet to discover why they create the toxins.
Aflatoxins, a family of mycotoxins, are poisonous compounds that have been designated by the International Agency for Research on Cancer as Group 1 carcinogens, meaning there is sufficient evidence they can cause cancer in humans. Aflatoxins also pose a greater risk to children by threatening their immune systems and growth.
"Aflatoxins in the U.S. are not much of a big problem because of development," Ouma said. "But where I come from in Kenya, it is one of the hotspots. There was a time people died because they consumed corn contaminated with aflatoxins."
According to research published in 2020 by the Journal of Young Investigators, in 2004, Kenya saw the most extreme aflatoxin outbreak in the world, which included 317 cases and 125 deaths.
Griffiths Atungulu, food science associate professor and director of the Arkansas Rice Processing Program, serves as Ouma's adviser and co-author. Other co-authors included Kaushik Luthra, a food science postdoctoral fellow, and Abass Oduola, a former food science doctoral student.
The project is part of Ouma's larger research objective on the safety of ready-to-eat rice products, such as instant rice, that she will maintain as she pursues her doctorate. For her rice safety research, she earned the first-place award from the Arkansas Association for Food Protection for her poster in the Interventions, Pre- and Post-Harvest division in 2022. She was also recognized as outstanding presenter at the American Society of Agricultural and Biological Engineers Annual International Meeting for her oral presentation the same year.
Aflatoxin contamination poses an even greater risk with products such as instant rice and rice cakes. Atungulu noted that a producer's window for mitigating this risk is in the early stages of rice processing. In later processing to create products such as instant rice and rice cakes, even high temperatures reaching 200 degrees Celsius, or 392 degrees Fahrenheit, won't eliminate aflatoxins once they are produced. Even if high temperatures were effective in destroying the aflatoxin, they would likely degrade nutritional quality.
"Once the toxin's been formed, the grain becomes almost useless," Atungulu said.
Researchers set out to understand how to prevent aflatoxin formation by measuring how temperature, humidity, storage time and moisture impacted the toxin's growth.
Rice from a farm in Hazen was collected and divided into rough, brown and milled rice fractions. Rough rice is unprocessed and still has its hull, or hard protective covering, while brown rice does not. Milled rice has its hull and bran layers removed. Samples of each type of rice were then divided into autoclaved, or steam-sterilized, and non-autoclaved. All samples were inoculated with Aspergillus flavus, a type of fungus that produces aflatoxins, and the team then tracked aflatoxin levels.
"We were looking at what the environments are that would make these fungi feel so confident to start producing the toxin," Atungulu said.
The researchers measured ergosterol, a substance in the fungus cell walls, and the quantity of Aflatoxin B1, a potent toxin linked to liver cancer and immune system suppression. Researchers found that temperature and relative humidity levels had the most significant impacts on fungal growth, and they had an even greater impact when present together. They also found that brown rice had notably high Aflatoxin B1 levels due to the fats in its bran, which can provide carbon for increased fungal growth and aflatoxin production.
Ouma's study showed that proper rice storage conditions to reduce aflatoxin risk after harvest include a temperature below 20 degrees Celsius, or 68 degrees Fahrenheit, and relative humidity below 75%. While the research involved careful measurements of fungal and aflatoxin levels at various temperatures, humidity levels, and other parameters, Ouma said she hopes the impact of her work is twofold.
"As much as I want to publish data, I also want to come up with something that can help solve a real-world problem when I go back home," Ouma said.

By Robert C. Jones Jr. [email protected] 07-12-2024
From afar, Quinton Lawton could only watch with angst as the first hurricane to strike the coast of his home state of Texas in nine years turned the communities of his childhood into muddy lakes.
It was late August of 2017, and Lawton was an undergraduate living in College Station, Texas, watching video news feeds of the damage powerful Hurricane Harvey had wrought in his hometown of Houston, 95 miles away.
“Many of the neighborhoods where I grew up were underwater, and the National Guard was staging rescue missions out of some of the schools I had attended,” he recalled. “My entire family was living in Houston, and all I could think about was helping in some way to mitigate the impacts of extreme weather on people and communities.”
It was then that Lawton, long enamored with the field of meteorology, decided to immerse himself in tropical cyclone research.
He completed his undergraduate studies in College Station in 2019, then discovered the world-class hurricane research program at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science . He moved to South Florida from the Lone Star State to pursue a Ph.D. in atmospheric sciences and delve deeply into the field of tropical cyclone genesis.
“It’s still an area we struggle with—the timing of and how hurricanes form,” Lawton said. “We’ve gotten a lot better in track and intensity forecasts of hurricanes, and we’re getting a slightly better handle on rapid intensification. But hurricane genesis is still something that often takes us by surprise, especially when we look beyond a few days.”
To help solve the conundrum, Lawton has looked closely at African easterly waves (AEWs), which propagate westward across the Atlantic Ocean and are a key factor in the formation of tropical cyclones and Atlantic hurricanes. “They’re the primary seed of storms that typically form in the Atlantic,” said Lawton, who recently published a study focusing on Kelvin waves and their impact on extreme weather events.
Approximately 60 African easterly waves track across the Atlantic each year, but most never develop into tropical cyclones at all.
Lawton wanted to get a better understanding of why. So, he has looked closely at how AEWs interact with other phenomena in the tropical atmosphere, one of those phenomena being convectively coupled Kelvin waves.
Over 1,000 miles long, Kelvin waves travel in Earth’s atmosphere along the equator and significantly influence global rainfall patterns. Some scientists had long believed that they might affect African easterly waves, but prior to Lawton’s comprehensive Ph.D. studies on the subject, only a handful of studies explored that possibility.
So, during the first phase of his doctoral research, Lawton used reanalysis data of past weather and climate to statistically isolate the role Kelvin waves play in affecting the strength of AEWs. He also conducted controlled experiments with an advanced weather model, testing whether he could strengthen or weaken Kelvin waves in a simulated format.
“The end goal, of course, is that if we can understand the dynamics of these waves, we can build better forecasts and give communities and emergency managers better lead time to prepare,” said Lawton, a former recipient of a prestigious National Science Foundation (NSF) Graduate Research Fellowship. “But we’re equally interested in the role Kelvin waves play in the tropical weather system. In addition to affecting hurricanes, they also bring torrential rainfall and can contribute to major flooding events, especially in Africa.”
Lawton has reported extensively on his findings. In a previous study , for example, he and his faculty advisor, Rosenstiel School professor of atmospheric sciences Sharanya Majumdar , explained how Kelvin waves can encourage tropical cyclone formation in the Atlantic.
And in another, he collaborated with scientists from the NSF National Center for Atmospheric Research (NCAR) to show how increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of some Atlantic hurricanes to form.
His work has taken him out into the field. As part of NASA’s recent Convective Processes Experiment airborne field campaign, conducted out of the West African island country of Cabo Verde, he assisted in investigating atmospheric dynamics, marine boundary layer properties, convection, the dust-laden Saharan air layer, and their interactions across various spatial scales. These efforts aim to improve the understanding and predictability of process-level lifecycles in the data-sparse tropical East Atlantic.
“He thinks in great depth about scientific problems, always wanting to understand things to the best level that he possibly can,” Majumdar said of Lawton.
Outreach has been just as important to Lawton as conducting research. He participated in the organization ’Canes on ’Canes during his time at the University, giving scientific talks focusing on meteorology to elementary, middle, and high school students as well as community residents.
With his doctoral degree now secured, Lawton will soon begin a postdoctoral fellowship at NCAR, where he will continue his research in African easterly and Kelvin waves. “I’ll also explore more of the details of the atmospheric complexities that occur off the coast of Africa—work that has been inspired by the NASA field campaign in Cabo Verde,” he said.
The physics of tropical cyclone genesis is an area of investigation without end, Lawton said.
“It’s amazing to me even to this day, long after Hurricane Harvey and actually an earlier storm, Ike, that I experienced as an 11-year-old,” he said. “Hurricane Beryl is a great example of a humbling storm where you think you have all this knowledge, you think you know everything, yet it still finds a way to defy your expectations and to prove you wrong. And that’s because cyclone genesis is so complicated. We’ll discover something, but it will lead to five or six more questions.”
