    Oct 13 2025

    Dr. Elaine Guevara is a Lecturer in Evolutionary Anthropology at Duke University. She teaches biology and conducts research on the evolution of primates using molecular approaches. One area of Elaine's research examines the evolution of brain aging and how brain aging differs between humans and our primate relatives, including certain species of lemurs. When it’s time to relax, Elaine loves to read. She is particularly fond of Golden Age mysteries, similar modern mystery authors, investigative journalism, history, and social science content. In addition to reading, Elaine enjoys biking, being outdoors, exploring the mountains, observing wildlife, playing games, sipping wine, and hanging out with friends. She received her BA in biological anthropology from the University of California, Santa Cruz, and her MA in biological anthropology from Hunter College. During her master’s program, Elaine also worked at the American Museum of Natural History as an Archives Assistant and subsequently a Database Assistant. She then received her PhD from Yale University. Afterwards, Elaine conducted postdoctoral research at The George Washington University. She joined the faculty at Duke in 2021, and she also served briefly as a faculty member at the University of North Carolina Wilmington.

  • 833: Researching Alternative Splicing for Gene Regulation in the Immune System - Dr. Kristen Lynch
    Oct 6 2025

    Dr. Kristen Lynch is a Professor and Chair of Biochemistry and Biophysics at the University of Pennsylvania. Kristen’s research focuses on alternative splicing. Her lab is investigating how cells decide when to use an entire portion of the DNA instruction manual versus when to exclude parts of the instructions that are not useful or would be harmful. In particular, Kristen is interested in alternative splicing in the immune system and what happens when cells are faced with an immune challenge. When she’s not at work, Kristen loves being outdoors. She spends her free time kayaking, paddle boarding, biking, hiking, and doing yoga. She received her B.A. in biochemistry and her Ph.D. in biochemistry from Harvard University. Afterwards, Kristen pursued postdoctoral training at the University of California, San Francisco. She served on the faculty at the University of Texas Southwestern Medical Center prior to joining the faculty at the University of Pennsylvania in 2009.

    Sep 22 2025

    Dr. Louis L. Jacobs is Emeritus Professor in the Roy M. Huffington Department of Earth Sciences and President of the ISEM at SMU. As a vertebrate paleontologist, Louis studies the fossils of animals with backbones. His goal is to understand their evolution and how it fits together with the earth and the environment to present a holistic picture of our world. When he’s not working, Louis loves to look at rocks, tend to orchids, bind books, and spend quality time with his grandchildren. They are insatiably curious and interested in everything, including rocks, fossils, and space. He received his B.S. degree from the University of Southwestern Louisiana (now the University of Louisiana at Lafayette) and his M.S. and Ph.D. degrees in Vertebrate Paleontology and Evolution from the University of Arizona. After completing his training, he worked as a research paleontologist at the Museum of Northern Arizona, a geologist for the U.S. Geological Survey, a lecturer and a research associate at the University of Arizona, Head of the Division of Paleontology at the National Museums of Kenya. He joined the faculty at SMU in 1983. During his time at SMU, Louis has held leadership positions at the Dallas Museum of Natural History as well as the Shuler Museum of Paleontology at SMU, where he ultimately served as Director for 13 years. Louis has won numerous awards and honors for his scholarship, his service, and the books he has written, including the University Scholar/Teacher of the Year Award from SMU, the Joseph T. Gregory Award for Service to the Society of Vertebrate Paleontology, The Texas Earth Science Teachers Association Lifetime Membership and Friends of TESTA Award, and many others. In addition, he is a past Fellow of the Explorers Club, Past President of the Society of Vertebrate Paleontology, and ten fossil species have been named after him. In this interview, he shares more about his life and science.

  • 830: Physicist Figuring Out How Materials Deform and Fail - Dr. Karen Daniels
    Sep 15 2025

    Dr. Karen Daniels is a Professor in the Department of Physics at North Carolina State University. Karen’s lab investigates the physics of how materials change state (e.g. from solid to fluid), how they deform, and how they may ultimately fail. She studies these questions across a variety of length and time scales, from microscopic phenomena that occur in less than a second to shifts in land that occur on geologic timescales and may lead to landslides. Travel is a passion for Karen. While traveling, she loves hiking on mountain trails, eating delicious food, discovering new foods that she can try to make at home, reading books, knitting, and interacting with new people and places. She received her BA in physics from Dartmouth College. Karen then worked for about three years as a science teacher at Saint Ann’s School in Brooklyn before enrolling in graduate school at Cornell University where she earned her PhD in physics. She then conducted postdoctoral research at Duke University before joining the faculty at NCSU in 2005. Karen has been awarded a fellowship from the Alexander von Humboldt Foundation to support a yearlong sabbatical at the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany. In addition, Karen was the recipient of a National Science Foundation Early Career Development (CAREER) Award, the Equity for Women Award from NCSU, and the LeRoy and Elva Martin Award for Teaching Excellence. She has also been named a Fellow of the American Physical Society. In our interview, Karen shares more about her life and science.
