Research:

My research interests focus primarily on the study of galaxy evolution within different environments, specifically using data from galaxy redshift surveys. I am interested in both the process of defining extragalactic environments (at the local scale, i.e. groups and clusters; and Cosmic scale, i.e. filaments and voids), as well as the study of how galaxy properties vary as a function of their membership to these differing environments. I have been heavily involved with the Galaxy And Mass Assembly (GAMA; http://www.gama-survey.org) survey, and have extensive experience with obtaining and analyzing galaxy survey data. My other interests include astrostatistics, x-ray imaging, and lensing observations of high redshift galaxies.

My current work focuses on developing the newest generation of group catalogues for the Sloan Digital Sky Survey (SDSS; http://www.sdss.org), as well as the Dark Energy Survey Instrument's (DESI; http://desi.lbl.gov/) Bright Galaxy Survey; and to use these new group catalogues to deepen our understanding of the relationship between galaxies and the dark matter host halos they inhabit. In addition to this, I am using data from the GAMA survey to study the mechanisms by which galaxies in groups assemble baryonic mass.
