I use geometric and topological tools both within pure Math and in 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 data-analytic tools for neuroscience data, and taking inspiration from biological learning to develop machine learning algorithms.
