Research Interests

My research interests are predominantly in the areas of observational cosmology and galaxy studies. This work includes the use of weak gravitational lensing and other analysis techniques, with projects that range from development of improved data analysis methods, to actual application of such methods to existing data. Currently, I am focusing on data from the Hyper-SuprimeCam (HSC) survey, and am working on upcoming surveys including the Rubin Observatory LSST and the Nancy Grace Roman Space Telescope. I am an active member of the , for which I served as Spokesperson from 2019-2021, and am now the lead at һ�� of the (press release).
