Research Interests

The research in our laboratory studies cellular and molecular mechanisms underlying HIV-1-associated neurocognitive disorders (HAND).  Specifically, we are interested in how virus and viral proteins impact 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.
