I am currently a (tenure track) lecturer in the School of Mathematics and Statistics at The University of New South Wales. Prior to this, I was a Research Fellow at Macquarie University (2021--2023), and before that I was an ACEMS Postdoctoral Research Fellow at The University of Queensland (2017--2021). I have obtained my PhD from the Tata Institute of Fundamental Research, Mumbai. I was a scientist at the Indian Space Research Organization (2008--2010) after completing a Master of Engineering degree at the Indian Institute of Science in 2008.

My research broadly focuses on problems in Probability Theory, Data Science, Statistics, Deep Learning, and Monte Carlo Simulation.
