The Gastronauts Podcast

Dr. Ranier Gutierrez is a Professor in the Department of Pharmacology at CINVESTAV in Mexico City. His life’s work is centered around the basic human need to control our appetite. (For food that is, there is no need to control your appetite for discovery!!! 😉) In his laboratory, they use cutting edge technology to to read minds as the subject eats in order to better understand what is the circuit...

Dr. Michael Krashes is a Senior Investigator at the NIDDK in the NIH.  His laboratory is on a mission to decipher the wiring diagram for hunger. His current work seeks to uncover the secrets behind our most primal instincts for survival, such as, the oscillating interactions between self-preservation and  food-seeking to optimize behavior. His research is shedding light on the intricate mechanisms...

Dr. Laura Duvall (Columbia) investigates the neurobiological mechanisms underlying mosquito behavior, including the regulation of host-seeking after blood-feeding, circadian and seasonal biting rhythms, and mating behavior. She employs pharmacological and genetic approaches to uncover the neuropeptide pathways and anatomical circuits involved in these behavioral switches, shedding light on fundame...

Dr. Scott Waldman's research at Thomas Jefferson University explores the mechanisms underlying visceral pain and how neuropod cells communicate with innervating spinal neurons. His work focuses on the role of the specific protein GUCY2C as a mediator of activity and a potential therapeutic target for treatment. 

Dr. Nick Betley's work at the University of Pennsylvania focuses on how hypothalamic circuits are regulated to influence food intake. On the podcast, we discuss the integration of pain and hunger in hunger circuits—examining when pain outweighs hunger and vice versa.

The 2023 Bite Size Summit, featuring four amazing early career scientists, Drs. Servin-Vences, Scavuzzo, Lough and Biswas, who study biological sensors for stretch, the functions of glial cells and the fascinating development of senses or lack thereof!

Dr. Greg Suh explores the fascinating world of how brains process external stimuli and generate behavioral responses. Using the fruit fly and advanced genetic tools, his group at KAIST investigates the neural substrates behind innate behaviors. They're also delving into the identification of internal sensors for nutritional value in both fruit flies and mice, shedding light on how mammals per...

Emily Liman, Ph. D., is a Professor of Biological Sciences at the University of Southern California. Dr. Liman is a world-renowned sensory neurobiologist who has advanced our understanding of taste perception through her groundbreaking discoveries including that of the OTOP channel—a key player in our ability to perceive the sour taste of a juicy lemon.

Andrea Gomez, Ph. D., is an Assistant Professor at the University of California Berkeley. Andrea’s laboratory seeks to understand the mysteries of the mind at the intersection of psychedelics and plasticity. The laboratory uncovers how these trippy compounds shake up our synaptic playground by using a combination of molecular biology, functional imaging, and slice electrophysiology to understand n...

Join our conversation with Ilya Raskin, famous for his work on plant growth regulation, plant immunity to diseases, phytoremediation, and, in the last decade, for his research in plant-derived functional foods and medicines. He is also actively involved in international bioexploration, conservation and is an amazing photographer!

Join us in our chat with Dr. Brian Gulbransen, from Michigan State University. His laboratory studies how inflammation in the nervous system leads to long-term changes in gastrointestinal function; and how glia, immune cells and the neurons in the gut communicate.

Dr. Maude David is an Assistant Professor at Oregon State University. Her laboratory studies the microbial gut-brain connection, and how microbes impact behavior, specifically in Autism Spectrum Disorder and anxiety.

Join us in our talk with the amazing Dr. Greg Gage, CEO and co-founder of Backyard Brains, an engineer and neuroscientist designing open-source tools to bring advanced neuroscience into classrooms and designing robots that help us understand how neurons produce behavior.

Join us in our talk with Dr. Polina Anikeeva, a material scientist and engineer leading a group at MIT that develops cutting-edge devices to understand and modulate the brain and other body systems.

Our very own 2022 Bite Size Summit, featuring four amazing early career scientists studying the brain-body connection and the effects of microbiome and diet across different species, join us in our conversation with doctors Valerie Darcey, Aki Ohdera, Nikki Pelot and Shawn Spencer. 

The road to scientific discovery is never a straight line, join our conversation with Dr. Heidi de Wet from Oxford, a researcher of the mechanisms of blood sugar and body weight regulation.

What do sensory deprivation tanks and therapeutic ingestible vibrating pills have in common? Learn about your "gut feelings" and interoception with Sahib Khalsa, M.D., Ph. D. of the Laureate Institute of Brain Research.

Dr. De Roode is a Professor of Biology at Emory University. He is perhaps the world’s foremost expert on monarch butterflies. His team is documenting how these beautiful creatures use plants for self-medication to treat themselves and their offspring against parasites.

Tune into our talk with Dr. Eleva Gracheva on how studying the hibernation of ground squirrels can lead us to new insights about our own health and eating disorders, and in the future, help us create new tools for deep-sea diving and space exploration.

The Gastronauts podcast is back with Dr. Andrew Huberman and Dr. Temple Grandin. Tune in to learn about finding your voice and sharing your vision.

In this session, we invite Dr. Nick Betley, an Assistant Professor of Biology at the University of Pennsylvania, and Dr. Dan Drucker, a Professor of Medicine at the University of Toronto to share their thoughts on research. We talk about how signals from the gut communicate with areas in the brain to direct us towards what we want to eat. And along the way discuss of the importance of acknowledgin...

In this session, we invite Dr. Piali Sengupta, a Professor of Biology at Brandeis University and Dr. Bryan Gulbransen an Associate Professor of Physiology at Michigan State University, to share their thoughts on how the bacteria and viruses that can get in our gut affect our body as well as how the research that they do affects their day-to-day lives. 

In this virtual Bite Size Summit, we have a panel of four incredible scientists who have all recently published some fascinating research findings. We have Dr. Kara Marshall from Scripps Research, Dr. Dafni Hadjieconomou from Imperial College London, Dr. Marcelo Zimmer from Yale and the Federal University of Rio, and Dr. Yuuki Obata from the Crick Institute of London. They share their perspectives...

In this session, we invite Dr. Mary Estes, a distinguished professor at Baylor College of Medicine and Dr. Dylan Dodd an Assistant Professor at Stanford University, to share their thoughts on how the bacteria and viruses that can get in our gut affect our body as well as how the research that they do affects their day-to-day lives. 

In our second virtual session, we invite Dr. Michael Krashes, an Section Chief at the National Institutes of Health, and Dr. Yulong Li, a Professor at Peking University, to share their thoughts on the latest and greatest tools to use in behavioral tracking and molecular biology as well as the importance of finding successful role models in research.
