I am a postdoc with Prof. Richard Mott at the Department of Genetics, Evolution & Environment in University College London. I completed my PhD in the Computational and Statistical Physics Lab working with Prof. Murugesan Venkatapathi at the Department of Computational and Data Sciences in the Indian Institute of Science, Bengaluru, India. I did my Masters in Computational Science from the same department. I did my Bachelors in Electronics and Communication Engineering from PSG College of Technology, Coimbatore, India.
