Professional Summary:

Dr. Popescu is a leading expert in molecular neuroscience. She studies the activation and modulation of NMDA receptors, the most abundant glutamate-stimulated, calcium-conducting channels in the brain and spinal cord. These receptors have essential roles in memory formation and learning. Importantly, their dysfunction results in severe neuropsychiatric disorders, including stroke, neurodegenerative conditions, chronic pain, and addiction as well as mental disorders such as schizophrenia and epilepsy. Results from Dr. Popescu's research help to establish direct correlations between the biophysical properties of NMDA receptors and mechanisms for synaptic transmission and plasticity in the central nervous system to guide strategies that maintain or restore behavioral health and well-being across the lifespan.

Dr. Popescu investigates how structural features of the NMDA receptors generate their electrical output, using a range of biophysical and biochemical methods. Among these are highly specialized biophysical techniques such as single-molecule electrophysiology, patch-clamp fluorometry, kinetic modeling of single-channel currents, and molecular dynamic simulations. Funds from the NIH have continuously supported Dr. Popescu's research projects and the training of several graduate and postdoctoral fellows working under her mentorship.

Dr. Popescu has been recognized internationally with the Sharona Gordon Award for her "clear and sustained impact on improving equity and inclusivity in the fields of physiology and biophysics" and with the AAMC Distinguished Service Membership for her "sustained service to the academic medicine community". She served on the AAMC Board of Directors, as the President of the Biophysical Society, and is an honorary Fellow of the American Association for the Advancement of Science.
