People Behind the Science Podcast Stories from Scientists about Science, Life, Research, and Science Careers

Dr. Lauren Ponisio is an Assistant Professor in the Department of Biology at the University of Oregon. Lauren's research revolves around preserving and restoring bee populations in agricultural areas and other natural habitats. She is interested in understanding the distribution and health of different populations of native bees. When she's not working, you can often find Lauren in her garden. She has been an avid gardener since childhood, and she currently has a thriving garden with lots of vegetables and plants to attract bees and other pollinators. She received her B.S. degree in biology with honors in ecology and evolution, as well as her M.S. degree in biology, from Stanford University. Lauren was awarded her Ph.D. from the Department of Environmental Science Policy and Management at the University of California, Berkeley. She conducted postdoctoral research at UC, Berkeley afterwards, and she served on the faculty University of California, Riverside before recently accepting her current position at the University of Oregon. Lauren received graduate fellowships from the National Science Foundation and the National Institute for Food and Agriculture, as well as a Postdoctoral Fellowship from the Berkeley Institute for Data Science. She was also named among the Global Food Initiative's "30 Under 30" in Food Systems in 2016. In our interview, Lauren shares more about her life and science.

Dr. Greg Wilson Mantilla is a Professor in the Department of Biology, Adjunct Professor in Department of Earth & Space Sciences, Curator of Vertebrate Paleontology at the Burke Museum, and Director of the DIG Field School at the University of Washington. He is also a Research Associate at the University of California Museum of Paleontology. His research explores the evolution of mammals that lived alongside dinosaurs and how mammals have diversified over time. Remarkable fossil discoveries have revealed that these early mammals were far more diverse than once thought, including species adapted for digging, climbing, gliding, and even feeding on small dinosaurs. Outside of science, Greg enjoys staying active, spending time with his family, and following sports. Playing soccer has long been a favorite pastime, and Greg now enjoys coaching his two children. He also enjoys watching soccer and other sports, working out, reading, traveling, and relaxing with movies and TV shows. Greg received his B.A. in Human Biology from Stanford University and his Ph.D. in Integrative Biology from the University of California, Berkeley. Afterwards, he received an NSF Fellowship to conduct postdoctoral research at the University of Helsinki. Before moving to the University of Washington, Greg was Curator of Vertebrate Paleontology at the Denver Museum of Nature & Science. Greg was awarded the Raymond M. Alf Award for Excellence in Paleontological Research & Education from the Raymond M. Alf Museum of Paleontology, and he received the University of Washington's Bergstrom Award for Art and Science (with Ari Rudenko). In this interview, Greg shares more about his life and science.

Dr. Julia Bailey-Serres is Director of the Center for Plant Cell Biology and Distinguished Professor of Genetics at the University of California, Riverside. She also holds the University of California John D. and Catherine T. MacArthur Foundation Chair and is Professor of Rice Physiology at Utrecht University in the Netherlands. A major focus of Julia's lab is to investigate how plants survive water extremes with the goal of improving the ability of crops to survive a temporary flood. When she's not working, Julia enjoys gardening, hiking, traveling, and spending time with her friends and family. She also has fun baking and cooking with fresh vegetables from her garden. She was awarded her B.S. in biology from the University of Utah and her Ph.D. in botany from the University of Edinburgh. Afterwards, Julia conducted postdoctoral research at the University of California, Berkeley before joining the faculty at UCR. She has received many awards and honors over the course of her career, including being named an elected Member of the U.S. National Academy of Sciences, a Fellow of the American Association for the Advancement of Science, and a Fellow of the American Society of Plant Biologists. In addition, she has been recognized with the Stephen Hales Prize from the American Society of Plant Biologists. In our interview, Julia shares more about her life and research.

Dr. Alan Cohen is Associate Professor of Environmental Health Sciences, Chair of Biological Complexity and Healthy Longevity, and Co-Director of the Science of Health Program in the Robert N. Butler Columbia Aging Center at Columbia University. In his research, Alan takes a theoretical biology approach to some of the biggest questions in science, including what aging is and what it means to be alive. Rather than viewing biology only as a collection of individual genes, molecules, and cells, he studies how these components interact as complex dynamic systems to maintain the internal balance that supports health. His work explores how the breakdown of these interconnected systems may underlie aging and disease, and how scientists can develop new ways to measure and understand these changes beyond traditional reductionist approaches. When he's not working, Alan enjoys practicing Aikido, a martial art he first learned while living in Japan. He also does contact improvisation dance, where partners use spontaneous points of physical contact to create movement together without knowing where the dance will lead. He received his Bachelor of Science degree in Biology and Asian Studies from the University of Michigan, Ann Arbor, and he was awarded his PhD in Biology from the University of Missouri-St. Louis. Afterwards, Alan completed postdoctoral research at Johns Hopkins University, the University of Toronto, and the University of Sherbrooke. He then served on the faculty at the University of Sherbrooke for about 12 years before accepting a position at Columbia University in 2022. Alan has received various awards and honors, including the Canadian Institutes of Health Research (CIHR) Institute of Aging New Investigator Prize of Excellence in Research on Aging and the CIHR New Investigator Salary Award. In this interview, he shares more about his life and science.

Dr. Isaac Harris is an Associate Professor in the Department of Biochemistry and Biomolecular Sciences and the Center for Discovery in Cancer Research at McMaster University. Isaac's research examines the roles of antioxidants in health and disease, including how they are produced and used in cells. He is particularly interested in how cancer cells rely on antioxidant pathways to survive and grow. Isaac is working to understand why high-dose antioxidant supplements may sometimes promote cancer rather than prevent it, and whether blocking cancer cells' natural antioxidant systems could slow tumor growth. When he's not working, Isaac enjoys spending time with his wife and five-year-old daughter, doing things like coloring, playing outside, visiting the park, or eating ice cream. He also likes cooking, reading, relaxing, watching TV, and introducing his daughter to some of his favorite childhood shows like The Simpsons. He received his bachelor's of engineering degree in chemical engineering and PhD in molecular biology from the University of Toronto. Next, he conducted postdoctoral research at Harvard medical school before joining the faculty at the University of Rochester and Wilmot Cancer Institute in 2019. In 2024, he was awarded the Wilmot Community Outreach and Engagement (COE) Innovator Award. He very recently moved his lab and joined the faculty McMaster University. In this interview, Isaac shares more about his life and research.
