Dr. Alexis “Lekki” Wood is Associate Professor at USDA/ARS Children's Nutrition Research Center in the Division of Pediatrics-Nutrition at Baylor College of Medicine. Research in Lekki’s lab aims to better understand how food influences our health. She examines the full chain of changes that occur from the moment food is put into our mouths, trough digestion and absorption of particular molecules, to where those molecules go and how they affect our organs. Outside of work, you can find Lekki working out at the gym and spending quality time with her two children and their German shepherd. She is also a Lego builder and a competitive Pokemon card player along with her son. She received her BSc with honors in Psychology and from the University of Warwick. Afterwards, she completed her Postgraduate Certificate in Education at the University of Cambridge. Lekki enrolled in graduate school at King’s College London where she earned her MSc in social, genetic, and developmental psychiatry and her PhD in statistical g

Dr. Gareth Fraser is an Associate Professor in the Department of Biology at the University of Florida. Gareth is a developmental biologist interested in how things form during development, how they are recreated during regeneration, and how features develop and persist on evolutionary timescales. His lab typically examines these questions looking at oral teeth and dermal denticles (tooth-like structures) in unusual fish like pufferfish, hammerhead sharks, and ghost sharks (chimaera). When he’s not working, Gareth enjoys being outside in nature, playing soccer, scuba diving, and hunting for fossils in the creek near their home. He and his two young daughters have also been having fun exploring the mysterious realm of cryptozoology and reading books about monsters. Gareth received his bachelor’s degree in palaeobiology and evolution from the University of Portsmouth, his master’s degree in evolutionary biology and systematics from the University of Glasgow, and his PhD in evolutionary developmental biology from

Dr. Steve Ramirez is an Assistant Professor in the Department of Psychological and Brain Sciences at Boston University. In his research, Steve is studying learning and memory, and he is interested in discovering whether it is possible to artificially turn memories on and off. His research focuses on understanding the brain and what we can do when processes in the brain break down. They are working on turning on positive or negative memories in animal models to gain a better understanding of how the brain and memory work. In addition, they use animal models of conditions like depression, anxiety, and PTSD to study whether artificially manipulating memories may alleviate some of the symptoms of these conditions. Steve was born and raised in the Boston area, so accepting a faculty position at Boston University meant reuniting with his family, friends, and beloved New England Patriots. He spends his down time watching Netflix with friends and hanging out with his family. He attended Boston University for his unde
