Research Interest

I am an evolutionary biologist and my study system is the fruit fly Drosophila melanogaster. My research interest lies at the interface of evolution and development. I use an approach called experimental evolution (or, laboratory selection) to study evolution in real time. In this approach, large populations of flies are subjected to specific selection pressures within the laboratory and allowed to evolve for many generations. How flies adapt to the applied selection pressures over generations are then studied in great details to understand the process of adaptive evolution. Drosophila is an excellent model system for experimental evolution studies because of its short generation time and easy manipulability under laboratory conditions.

During my PhD, I used experimental evolution to study various evolutionary correlates of rapid development in Drosophila. My work showed evolution of reproductive isolation between faster developing populations of flies and their relatively slow growing ancestors, within a span of few hundred generations, mediated by body size divergence between the two lineages. The focus of my postdoctoral research on the other hand, was studying various mechanistic aspects of body size regulation in flies.

Body size in fruit flies can evolve through genetic changes (over multiple generations). Moreover, fly size is also environmentally plastic, that can change depending on developmental temperature, nutrition, rearing density etc. (in a single generation). In addition, different body parts or organs of the fly show varying levels of phenotypic plasticity. I am interested in how body and organ sizes of Drosophila melanogaster, and their plasticity evolve in response to different environmental conditions. I am also inetrested in the genetic basis of plasticity (the phenotypic change in a trait in response to environmental changes) , and its relationship with evolution.

I have recently joined KIIT, Bhubaneswar and currently working towards developing a fly laboratory where I plan to start working on an experimental evolution project (funded by the Department of Science & technology, Govt. of India) to explore the relationship between plasticity and evolution.

Teaching

I teach two introductory biology courses at KIIT School of Biotechnology for its B.Tech-M.Tech dual degree those cover the basics of genetics, developmental biology, ecology and evolution, among other things.

Since 2016 I have been teaching a masters level course on Evolutionary Biology at NISER, Bhubaneswar for their integrated MSc. Course, as a part time visiting faculty.
