Dr. Elizabeth Catania is a neuroscience researcher, assistant professor, Director of Undergraduate Studies and Director of Independent Studies at Vanderbilt University.
In this episode, guest host Lucy Pohl, who is the high school intern for the podcast, interviews Dr. Catania talks about her research and path as a scientist.
Highlights of the episode:
*High school intern Lucy Pohl introduces Dr. Elizabeth Catania of Vanderbilt University and outlines her background in neuroscience and education [~1:20];
*Lucy asks Dr. Catania about how her passion for science originated and how she became interested in neuroscience [2:42];
*Dr. Catania describes starting college as an English major and not discovering her love of science until later [~3:20];
*How an introductory neuroscience course taken “just for fun” changed her academic trajectory and led her to switch majors [~4:05];
*Why students don’t need to “find their thing” in middle school or high school—and why trying new subjects matters [4:58];
*Lucy asks about Dr. Catania’s postdoctoral work at the Vanderbilt Kennedy Center and how working with individuals with autism influenced her approach to neuroscience [~6:20];
*Connecting basic neuroscience research to real people and real-world challenges [7:18];
*Lucy asks Dr. Catania to explain what the nervous system is for students who may not have studied it in depth [~8:05];
*What the nervous system does: how neurons, sensory input, and brain processing allow us to interact with the world [~8:35];
*Dr. Catania discusses comparative neurobiology and how studying different animals helps scientists understand how nervous systems are built and specialized [9:39];
*Lucy asks about technologies that have helped scientists understand the nervous system, including MRI and genetic manipulation [11:55];
*What brain circuitry is and how connections between neurons drive behavior [~13:05];
*How illusions (like the blue/black vs. gold/white dress) reveal how the brain processes sensory information [~14:35];
*Using fMRI to measure connectivity and activity in the brain—and what scientists mean by “higher” or “lower” circuit strength [16:13];
*Why understanding brain circuitry is critical for studying conditions like autism and ADHD [~17:35];
*Connecting neuroscience research to hierarchical systems—from behavior down to genes [~19:05];
*The “cold dog and fireplace” example—moving from behavior to brain regions to cells, proteins, and genes [20:31];
*Discussion of women in STEM: progress made, ongoing challenges, and mentorship as a source of pride [~23:05];
*Field-specific differences in representation of women, including contrasts with engineering [25:01];
*Advice for middle and high school students: follow your interests, don’t fear detours, and allow yourself to change direction [~26:05];
*Incorporating humanities into science education and the importance of communicating science clearly [~28:05];
*Vanderbilt’s first-year core course, “Science, Technology and Value,” and creating a common intellectual experience across disciplines [29:40];
*Why integrating science with humanities benefits both STEM and non-STEM students [32:01];
*Majors that bridge science and humanities, including communication of science and technology and medicine, health, and society [34:17];
Recommended science books for students, including The Beak of the Finch and Why Zebras Don't Get Ulcers[~37:05];
*Advice for students who feel pressured to choose a single academic pathway too early [38:42];
*Current neuroscience research Dr. Catania finds exciting: brain organoids and the future of personalized medicine [~41:05];
*Closing reflections on science, humanities, and intellectual curiosity [43:18];
*Episode wrap-up, listener feedback information, and acknowledgments of the Science Fare intern team [~43:50].
