First person – Vishwanath Varma

First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping early-career researchers promote themselves alongside their papers. Vishwanath Varma is first author on ‘ Accuracy of fruit-fly eclosion rhythms evolves by strengthening circadian gating rather than developmental fine-tuning ’, published in BiO. Vishwanath conducted the research described in this article while a PhD student in Prof. Vijay Kumar Sharma's lab at the Jawaharlal Nehru Centre for Advanced Scientific Research, India. He is now a postdoctoral fellow in the lab of Dr V. V. Binoy at the National Institute of Advanced Studies, India, investigating the links between animal behavior, physiology and life history, and how they adapt to changing ecological conditions.
