Research Interests


My primary research interests are in theoretical and observational studies of what happens around the most bizarre objects in the universe: supermassive black holes in the centers of galaxies.  As matter spirals into these black holes, it produces a tremendous release of energy as what is called an "active galactic nucleus" or AGN for short.  AGNs are the most powerful energy sources in the universe (more powerful than an entire galaxy of stars).  Because they are so luminous they can be seen far away back in the early days of the formation of galaxies when the universe was young.

I am particularly interested in what the structure of AGNs is like, how the matter moves close to the black hole, and what the physical processes are which cause the matter to be accreted by the black holes and produce the intense radiation seen.  The aim is to understand how AGNs work in order to understand how black holes grow and the relationship to the galaxies they are in.

I like to work at the interface of theory and observation.  My research involves observations with giant telescopes on the ground, satellites in space, computer simulations, and sometimes just good old fashioned pencil and paper.  A lot of my work involves collaborations with astronomers around the world.

Teaching Interests

I enjoy teaching at all levels from introductory course for non-scientists to advanced graduate courses.  I also greatly enjoy working one on one with students on individual research projects, theses, etc.

I also teach "Physics and Psychophysics of Music", a joint course between the departments of Music and Physics at UCSC.
