About Me

I am an incoming doctoral student in the Computer Science department at the University of California San Diego starting fall 2021. Previously, I was a Research Fellow in the Machine Teaching Group at Max Planck Institute for Software Systems, where I had the great fortune to be advised by Dr. Adish Singla. I have also worked as a graduate student in the Department of Computer Science at Aalto Univerity (Finland) from September 2018 to August 2019. Prior to that, I completed my BSc in Mathematics and Computer Science (2013-2016) and MSc in Computer Science (2016-2018) from Chennai Mathematical Institute (CMI, India) under the supervision of Prof. K Venkata Subrahmanyam.

I am broadly interested in the theoretical aspects of machine learning. More specifically, I’m interested in statistical machine learning, algorithms, interactive learning, optimization, and theory of deep learning. I’m enthusiastic to explore and apply ideas from probability theory, analysis, differential geometry, and statistics to understand the computational and statistical efficiency of learning methods, and the extent to which machines can learn from data.

Some Hobbies

I have been playing piano for a number of years and have been lucky to have some formal training to grade 2. Recently, I have picked up on Ukulele, which could be approximately thought of as a miniature version of a guiter with 4 strings.
