Research Interests

Neuroinflammation: My lab is interested in gaining a better understanding of neuroimmune signaling in CNS disorders such as HIV Dementia, Parkinson’s disease, and Autism. Additionally, we are interested in identifying the mechanism by which pharmacologic agents such as opioids modulate neuroimmune signaling in astrocytes and microglia.
