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 SDSS (including SDSS-III and the ongoing SDSS-IV) and Hyper-SuprimeCam (HSC), and am working on upcoming surveys including LSST, Euclid, and WFIRST. I am an active member of the LSST Dark Energy Science Collaboration, for which I served as Spokesperson from 2019-2021, and am now the lead at CMU of the LINCC Frameworks Initiative (press release).
