Research Interests:  

In my post-doctoral training, I investigated the regulation of sphingolipid synthesis and the mechanism of intracellular lipid transport. I recently identified a novel mechanism by which cells promote lipid transfer at membrane contact sites, and the findings were published in reputed journals like Developmental cell, Journal of Lipid Research, and Biochimica et Biophysica Acta (BBA). After gaining research expertise in lipid metabolism, I sought to enter the area of neuroscience in the context of HIV and drug abuse. After joining Dr. Buch’s team, I am now applying my lipid expertise to neuroHIV and drug abuse. I am studying the exacerbation of neuroinflammation by iron-mediated lipid peroxidation (Ferroptosis) in a rodent model of HIV and drug abuse.
