Research Interests

Our laboratory studies cellular and molecular mechanisms underlying HIV-1-associated neurocognitive disorders (HAND), focusing on how virus and viral proteins  alter 1) neuronal physiology, synaptic transmission and plasticity via subtypes of NMDA receptors, and 2) mononuclear phagocytes (MPs, brain macrophages and microglia)-mediated neurotoxic activity via voltage-gated K channel Kv1.3.  How drug abuse, in particular methamphetamine, exacerbates HAND pathogenesis is another focus in our laboratory research.
