Our Team
Dr. Jessica J. Walsh (she/her)
Principal Investigator
Dr. Walsh is dedicated to understanding the neural circuits underlying motivated behaviors and their dysfunction in psychiatric diseases. She hopes that this will aid in the development of new therapeutic targets to help people who suffer from these disorders. Her journey began at Columbia University volunteering in Dr. Gerald Fischbach's laboratory and earning her B.A. in Neuroscience & Behavior. During her graduate work, she explored the neural circuit mechanisms underlying social stress susceptibility and resilience phenotypes in Dr. Ming-Hu Han's laboratory at the Icahn School of Medicine at Mount Sinai. Prior to joining the faculty at UNC, she completed her postdoctoral fellowship at Stanford University, under the guidance of Dr. Robert Malenka, where she sought to investigate the neural circuit mechanisms and synaptic functions in genetic mouse models with social deficits.
Dr. Roberto J. Morales Silva (he/him)
Post-doctoral Fellow
Roberto J. Morales Silva, Ph.D., is a first-generation graduate from Puerto Rico, where he completed his doctoral studies in Biomedical Sciences at Ponce Health Science University under the mentorship of Dr. Sepulveda-Orengo. His research focused on understanding the impact of chronic stress on cocaine self-administration and craving, with an emphasis on how stress alters glutamatergic projections from the basolateral amygdala to the nucleus accumbens. Roberto is passionate about advancing our understanding of the neural mechanisms underlying social behavior and is eager to contribute while learning new skills in neurocircuitry, molecular biology, and behavioral analysis.
Pierre Llorach (he/him)
Ph.D. Graduate Student
Pierre received his B.S. in Cognitive Science with a Neuroscience emphasis from UC Davis. He then joined the Multidisciplinary Association for Psychedelic Studies (MAPS) as a Clinical Study Assistant where he aided in phase 2/3 clinical trials investigating the efficacy of MDMA assisted psychotherapy for treatment of PTSD. Following his time at MAPS, he wanted to learn how to probe the molecular mechanisms behind novel treatments from the basic science perspective and joined Dr. Boris Heifets at Stanford University as a Life Science Researcher. In the Walsh lab, Pierre hopes to investigate and characterize GPCR signaling in-vivo leveraging circuit and cellular techniques.
Hayleigh Tilton (she/her)
Ph.D. Graduate Student
Hayleigh graduated from Florida State University with her B.S. in Psychology and a minor in Chemistry. After discovering her love for research within FSU’s Undergraduate Research Opportunities Program, she went on to be a Research Program Coordinator and Research Program Supervisor at Johns Hopkins’ Cannabis Science Lab where she coordinated multiple clinical cannabis-dosing trials. Her primary work there includes a characterization of the pharmacokinetics and pharmacodynamics of topical hemp products with Dr. Tory Spindle and of combinations of THC, CBD, and caffeine with Dr. Justin Strickland. With a passion for pharmacology, she then joined the Walsh Lab at UNC with the goal of building a deeper understanding of how new therapeutic drugs and serotonergic circuits affect behavior and the brain.
Sarah McDaniel (she/her)
Research Technician
Sarah graduated from North Carolina State University with a bachelor's degree in psychology and minor in biology. She is interested in understanding how genetic and environmental factors impact neural function in neurodevelopmental disorders. Her ultimate goal is to become a significant contributor to the development and implementation of cutting-edge therapeutics to treat these conditions to improve the daily lives of those affected by these disorders.
