Department of Zoology



I completed my master’s in Wildlife Biology from A.V.C College, India. For Master’s thesis, I worked on a seasonally polyphenic butterfly Common Evening Brown (Melanitis leda) which exhibits wet and dry season forms. I carried out experiments to figure out environmental cues that govern the expression of alternative phenotypes. Currently, I am a graduate student in Paul Brakefield’s lab and the broad aim of my research will be to understand how seasonality drives the evolution of life-history traits in tropical Mycalesina butterflies.
