Biography

I am a brain resident at Google.

I am interested in computational aspects of statistics and optimization, with a focus on methods and techniques that interact with machine learning. I aim to improve our understanding of modern machine learning with tools from applied maths and use the derived insights to develop more efficient and reliable algorithms.

I am most experienced with Monte Carlo methods and numerical analysis.

I will be maintaining a blog here.
