Research
As a Ph.D. student at UC San Diego and postdoctoral researcher at the University of Utah I studied galaxy evolution at intermediate redshift using both observations and simulations. My focus was on refining models of the statistical relationship between galaxies and dark matter halos (the “galaxy–halo connection”) using large spectroscopic redshift surveys in combination with mock galaxy catalogs to address questions such as:
How does the relative importance of different galaxy quenching processes depend on various galaxy and halo properties?
Is the stellar-to-halo mass relation different for star-forming versus quiescent galaxies?
What are the best practices to make robust measurements of small-amplitude statistical effects in galaxy surveys at z > 0.2 where large, complete spectroscopic datasets are challenging to obtain?
How can existing galaxy surveys be combined with simulations to constrain empirical models of the galaxy–halo connection?
