I received my Bachelor’s degree in mathematics in 2010 from the University of Delhi, India, following which I was selected for the integrated Ph.D. program at the Tata Institute of Fundamental Research, Centre for Applicable Mathematics, Bangalore, India. During my Ph.D., I spent a year and a half at ETH Zurich, working with the research group at the Seminar of Applied Mathematics. I successfully completed my Ph.D. in May 2017.
