Title: Viewing the universe through gravitational lenses
Abstract: I will share my recent work on weak gravitational lensing –– how to extract nonlinear cosmological information beyond the traditional two-point function and how to calibrate lensing systematics using cross-correlations. I would also like to solicit ideas of interesting things that can be done with the large number of cosmological N-body simulations (~100 models, including neutrinos) I am about to run.
