Description:
I am a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. My research involves mapping the detailed distribution of dark matter in the universe exploiting the bending of light en-route to us from distant galaxies. In particular, I have focused on making dark matter maps of clusters of galaxies, the largest known repositories of dark matter.
