Tapasya Thapa, Project associate
Indian Institute of Science (2022-)
Born and brought up in a small city, Dehradun. Did my master’s in Biotechnology in 2018. It was my post-graduation dissertation that sparked my interest in the field of phylogenetics. Just after my masters, I joined Wildlife Institute of India, Dehradun and gained experience in conservation genetics tools and techniques. And since March 2022, I have been working as a Project Associate in Population and Community Ecology lab, Centre for Ecological Sciences, IISC, Bangalore. Here, I help with the molecular lab work and routine chemistry work. I am keen to understand the effect of the environment on the evolution of characters and the survival of these characters from the molecular point of view.
Apart from extracting and amplifying DNA, I love to dance and read some good fiction. Also, a music fanatic and yes, a major Potterhead.
