Kshiteej Sheth

I am a second year CS PhD student at EPFL working with Prof. Michael Kapralov. I am broadly interested in algorithms for massive datasets, with a focus on randomized algorithms for large scale numerical linear algebra, high-dimensional data analysis and optimization.

Previously, I worked with Prof. Ola Svensson during my MSc on clustering problems. Before that I worked with Prof. Anirban Dasgupta and Prof. Dinesh Garg (IBM Research, Bengaluru) on randomized linear algebra. I also spent a summer at Caltech on a SURF fellowship working with Dr. Ashish Mahabal on deep learning for astronomy.
