Research Interests:
Aaron's current research focus is the study of dark energy using images from the ongoing Dark Energy Survey (DES) and the future Large Synoptic Survey Telescope (LSST). He is interested in studying dark energy using both galaxy clusters and weak gravitational lensing. His research group connects instrumental work, in particular active optics and wavefront measurements at DES and a program of camera-wide testing at LSST, with cosmology measurements. For example, they are developing a new method to characterize the telescope+camera point spread function using optical data, to be part of the weak lensing data analysis at both DES and LSST.
