Research Interest :

Medicinal Chemistry and Natural Products Drug Discovery
My research interests encompass medicinal chemistry and natural products drug discovery with a special emphasis on the central nervous system (CNS) therapeutic area. Current projects involve the synthesis and SAR of analogues of CNS-active natural products as well as the isolation, semi-synthesis and SAR of compounds from plants possessing activity in the CNS
