Originally from the Indian Wells
Valley in California's Northern Mojave Desert, I attended Sherman E. Burroughs High School
(Class of 1979) in Ridgecrest,
California, otherwise known as the "Gateway to Death Valley", and home of the
China Lake Naval Air
Weapons Station (it was just NOTS, then NWC, when I was
there). While at China Lake I was a member of the China Lake Astronomical
Society, the folks who helped give me a start in Astronomy, and Boy
Scout Troop 35, to whom I owe my abiding love of the outdoors. In 1979
I left the desert to attend Caltech, where I received my BS in
Physics in 1983. At Caltech I was a member of Dabney House,
and a sometime member of the infamous InfraRed Army. I then
got out of Pasadena and headed north along the coast to the Lick Observatory at UC Santa Cruz, where I received my PhD in
Astronomy & Astrophysics in
1988. After a brief stint as a W.J. McDonald Postdoctoral Fellow at the
University of Texas at Austin, I
came to Ohio State as a postdoc in 1989, and then joined the faculty of
the Astronomy
Department in 1992 as an Assistant Professor. I have been a Full
Professor of Astronomy since 2003.
My primary research is concerned with the astrophysics of active galactic nuclei and gaseous nebulae as revealed through imaging and spectrophotometry at optical, UV, and infrared wavelengths with ground-based and space-based telescopes. My recent work has been in two main areas. The first seeks to refine measurments of the masses of supermassive black holes in nearby active galaxies with the goal of calibrating the key scaling relations that will allow us to extend local methods out to cosmological distances. The second uses the Hubble and Chandra space telescopes to study how local active nuclei are fed by gas from their host galaxies, and how that activity in turn feeds back upon their hosts. Closer to home, I am part of the MicroFUN collaboration based at Ohio State that has organized a worldwide network of amateur and professional telescopes to make coordinated observations to search for extrasolar planetary systems using gravitational microlensing.
To support this research I am actively involved in the design and construction of advanced astronomical instruments, including development of software for image processing, spectral analysis, and instrument control & data acquisition. Instruments I have helped develop are in regular use at the MDM Observatory in Arizona and on the SMARTS telescopes in Chile. My latest instrument project is the two MODS spectrographs we are building for the Large Binocular Telescope on Mt. Graham in Arizona.
