Current Research

I am working with Professor Liliya Williams. My current research is primarily focussed on Strong Gravitational Lensing. The main motivation of my work lies in finding free-form non-parametric inversions of galaxy clusters using strong gravitational lensing, dark matter dynamics in galaxy clusters and predictions of precision measurement of the Hubble constant using reconstructed time delay estimations. The core theoretical work is mainly related to reconstruction of galaxy cluster mass distributions using Grale, a genetic algorithm-based non-parametric method, which runs on a supercomputer.
