Dr. Hwa completed her Ph.D. at Tufts University focusing on the neuropeptides that underlie how stress increases alcohol drinking using mouse models. During her graduate career, she was awarded an NRSA F31 predoctoral fellowship from the National Institute of Alcohol Abuse and Alcoholism (NIAAA) and the Dissertation Research Award from the American Psychological Association. Dr. Hwa next sought postdoctoral training at the Bowles Center for Alcohol Studies at the University of North Carolina School of Medicine. There, she learned how to examine synaptic function with slice electrophysiology and circuit neuroscience techniques, training that led her to receive a Pathway to Independence K99/R00 Award from the NIAAA. In addition to research accolades, Dr. Hwa has also been formally recognized for her mentorship of undergraduate students during her graduate and postdoctoral training environments. Dr. Hwa joined the faculty of Baylor Psychology & Neuroscience and started her laboratory in January, 2021.
Dr. Hwa’s research focuses on the cells and circuits underlying how stress interacts with long-term alcohol drinking. Using mouse models, Dr. Hwa combines classical pharmacological methods with modern neuroscience strategies to answer fundamental questions in alcohol and stress behavioral neuroscience. This research laboratory seeks to understand the important external variables, such as social stress or the limited availability of alcohol, that contribute to excessive drinking in mice. Our exploration of the consequent neuroadaptations (e.g. dysregulated stress neuropeptides, alcohol-induced neuroplasticity) ultimately inform novel approaches for the behavioral prevention and pharmaceutical treatment of alcohol-related psychopathology.
