I am a Professor of Astronomy at Yale University. My research focusses on various aspects of cosmology, large scale structure, galaxy formation and dynamics. Among others, I study the Galaxy-Dark Matter Connection using Halo Occupation Statistics, study the structure and assembly of dark matter haloes, model the formation and evolution of disk galaxies, constrain cosmological parameters using galaxies as mass tracers, use galaxy groups to study galaxy quenching, and use constrained simulations to model the local Universe. I also use N-body simulations and analytical methods to study dark matter substructure, dynamical friction, impulsive heating and fuzzy dark matter. I have written over 190 papers in refereed journals and am also the author of the textbook Galaxy Formation and Evolution published by Cambridge University Press.


During the Fall 2021 semester I will teach ASTR 320: Physical Processes in Astronomy

During the Spring 2022 semester, I will teach a new course, ASTR 501: Dynamics of Astrophysical Many Body Systems
