At the University of Washington Peter Ferguson is a DiRAC postdoctoral fellow as well as a fellow in the eScience institute. Previously, he was a postdoc at the University of Wisconsin-Madison, where he was part of the observational cosmology group, and he completed his PhD at Texas A&M University.

Peter Ferguson is interested in learning about the nature of dark matter and galaxy formation using wide-field astronomical surveys such as the Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory.

In particular, he works on finding and characterizing stellar streams and dwarf galaxies in the local universe and enabling this science by making infrastructure level contributions to cosmological surveys. These contributions range from instrumentation and calibration to science validation and software development.
