Research

My research focuses on plant population genetics, conservation biology, molecular markers, and phytochemistry. Specifically, I investigate how various anthropogenic activities affect the genetics and population structure of high value medicinal plants and threatened species. Also, I research on how in vitro techniques can be utilized to produce valuable phytochemicals in order to reduce reliance on wild sources.
