Professor, Astronomy & Physics

Past Courses Taught

Astronomy 170: Introduction to Cosmology

Research Interests

Gravitational lensing—probing the distribution of dark matter on galaxy and cluster scales, in order to achieve a better understanding of the physics of their formation and evolution.

Accretion physics—probing the accretion history of supermassive black holes, and the dynamics of gas flows in Active Galactic Nuclei and X-ray binaries.

Galaxy formation—feedback processes from quasar outflows and supernovae in galaxy formation.
