876: Dr. Isaac Harris: Uncovering the Hidden Roles of Antioxidants in Health, Cancer, and Other Diseases
2026/08/03 | 55 mins.
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.
875: Investigating How Disruptions in the Gut Microbiome Impact Intestinal Epithelial Cells and Lead to Disease - Dr. Mariana Byndloss
2026/07/27 | 36 mins.
Dr. Mariana Byndloss is Assistant Professor of Pathology, Microbiology and Immunology at Vanderbilt University Medical Center. Research in Mariana's lab investigates how the bacteria that live inside our gut can affect our health. She is interested in how things like diet, antibiotics, or infection may change how our body behaves. This, in turn, can change how the bacteria in our gut behave and lead to disease. Outside of science, Mariana loves animals, and she spends a lot of her free time with her dog and new puppy. They are both German Shorthair Pointers, and she trains them to hunt and to participate in American Kennel Club competitions. Mariana also enjoys quality time with her husband and son, listening to live music, and exploring all the great restaurants in Nashville. Mariana earned her DVM, MSc in veterinary pathology, and PhD in veterinary pathology from the Universidade Federal de Minas Gerais (UFMG) in Brazil. She was awarded the Brazilian National Prize for best PhD thesis in Veterinary Medicine. Afterwards, Mariana conducted postdoctoral research at the University of California, Davis before joining the faculty at Vanderbilt University Medical Center. In our interview, Mariana will tell us more about her life and science.
874: Searching for Signs of Life on Mars and Beyond - Dr. Amy Williams
2026/07/20 | 47 mins.
Dr. Amy Williams is an Associate Professor in the Department of Geological Sciences and Assistant Director of the Astraeus Space Institute at the University of Florida. She is an astrobiologist who builds instruments and analyzes data from other worlds to help us try to answer the question of whether there is life on other planets beyond Earth. She is particularly interested in investigating whether there was once life on Mars. When Amy's not working, Amy enjoys spending time with her family and her cats. Some of her favorite pastimes include birdwatching, hiking, walking, and gardening. Amy received her B.S. in Earth & Environmental Science from Furman University, her M.Sc. in Earth and Planetary Sciences from the University of New Mexico, and her Ph.D. in Geology from the University of California, Davis. Afterwards, Amy accepted a position as a Postdoctoral Research Associate at the NASA Goddard Space Flight Center. She served on the faculty at Towson University before joining the faculty at the University of Florida in 2018. She has received several NASA group achievement awards for her work with the Curiosity and Perseverance rover teams, and she was awarded the Provost's Excellence Award for Assistant Professors from the University of Florida. She received the American Geophysical Union's Award for Advancing Inclusive Excellence in STEM with the GeoSPACE Field Program, and she was a NASA Earth and Space Science Fellow and a Scialog: Signatures of Life in the Universe Fellow. In this interview, Amy shares more about her life and science.
873: Finding Out How the Brain Controls Movement in Moths During Flight - Dr. Simon Sponberg
2026/07/13 | 54 mins.
Dr. Simon Sponberg is Dunn Family Professor and Assistant Professor in the School of Physics and the School of Biological Sciences, as well as Adjunct Assistant Professor in Biomedical Engineering at the Georgia Institute of Technology (Georgia Tech). Through his research, Simon is interested in understanding how the brain works with muscles to make bodies move. Animals move gracefully in nearly all environments on Earth, and many types of movement can be difficult to perform in robotics and other created systems. Simon uses animal models to study how the body and the muscles inform the brain in terms of the information we take in and how we react to the environment. When he's not doing science, Simon loves to cook. Cooking is an excellent creative outlet, it allows him to experience and understand other cultures, and it's fun to cook with people and enjoy the results together afterwards. Simon is also a big fan of hiking and spending time outdoors. He received his B.A. in physics and biology from Lewis & Clark College and his Ph.D. in Integrative Biology from the University of California, Berkeley. Afterwards, Simon conducted postdoctoral research at the University of Washington before joining the faculty at Georgia Tech. He has been the recipient of an NSF Postdoctoral Fellowship in Biological Informatics, the University of Washington Postdoctoral Mentoring Award, the Young Investigator Award from the International Society for Neuroethology, an NSF Faculty Early Career Development (CAREER) Award, a Klingenstein-Simons Fellowship in the Neurosciences, and a Hertz Fellowship. In our interview, Simon shares more about his life and science.
872: Uncovering the Mechanisms Underlying Uneven Rates of Evolution Across Organisms - Dr. Martha Muñoz
2026/07/06 | 52 mins.
Dr. Martha Muñoz is an Assistant Professor in the Department of Ecology and Evolutionary Biology at Yale University. Martha is an evolutionary biologist who is working to better understand how and why evolution proceeds unevenly across the tree of life. Some features and branches of organisms evolve really quickly, while others remain inert or nearly inert for millions of years. Martha's research is uncovering the mechanisms underlying this phenomenon, and she has discovered that behavior is a key architect of evolution. For Martha, nature is a wonderful source of peace and inspiration for her research. When she's not working, she enjoys exploring the outdoors, hiking, seeing amazing views, and observing wildlife. She also spends her free time reading, going to museums, and visiting her family in New York City. She received her B.A. in biology from Boston University. Afterwards, Martha worked as a Fulbright Research Scholar at the National Museum of Natural Sciences in Madrid, Spain. She was awarded her Ph.D. in Organismic & Evolutionary Biology from Harvard University. Next, Martha conducted postdoctoral research in the Research School of Biology at The Australian National University and subsequently the Department of Biology at Duke University. Prior to accepting her current position at Yale University, Martha served on the faculty in the Department of Biological Sciences at Virginia Tech. Martha has received numerous awards and honors, including the Boston University Department of Biology's Distinguished Alumni 'Rising Star' Award, and a Young Investigator Award from the American Society of Naturalists. She was also named a 'Scientist to Watch' by The Scientist Magazine in 2019. In our interview, Martha shares more about her life and science.
