Kyung-An Han

Dr. Kyung-An Han is a Professor of Biological Sciences and Associate Dean of the College of Science at the University of Texas at El Paso (UTEP). Her research focuses on the neurobiological mechanisms underlying behavioral plasticity, particularly the roles of dopamine, acetylcholine, and octopamine in regulating learning, memory, addiction, and impulsivity using the fruit fly Drosophila melanogaster as a model organism. She investigates how neuromodulators mediate responses to natural stimuli and addictive substances like alcohol, with implications for understanding human disorders such as Parkinson’s, schizophrenia, and dementia.

Her work has revealed critical roles of dopamine and acetylcholine in inhibitory control, directly addressing community health concerns in El Paso. Supported by grants from the National Science Foundation (NSF), her research bridges basic science and translational applications. Notable contributions include studies on ethanol-induced behavioral disinhibition, octopamine’s role in olfactory learning, and age-related neuromodulation deficits.

Dr. Han’s research also explores the intersection of social context and neurochemical signaling, exemplified by studies on how dopamine hyperactivity and ethanol interact under social conditions. Her findings highlight conserved neural mechanisms from flies to humans, offering insights into developing therapeutic strategies.

She teaches courses on ethical and social dimensions of science and mentors students in neurobiology. Her lab integrates genetic, behavioral, and biochemical approaches to dissect neural circuits governing complex behaviors.
