Research

I use geometric and topological tools both within pure Math and Computer Science. My main area of research is Machine Learning (statistical machine learning, topological data analysis) but I also work on certain problems in Contact/Symplectic Geometry as well as Computational Geometry. My focus in Machine Learning is its interaction with Neuroscience  understanding theoretical principles governing both artificial and biological learning, developing dataanalytic tools for neuroscience data, and taking inspiration from biological learning to develop machine learning algorithms.
