I am an
Professor in the Department of Physics
and Astronomy at George Mason University.
My current research interests focus on understanding the physical processes
taking place in the nuclear regions of infrared-bright galaxies.
A large fraction of
galaxies in the Universe are enshrouded in dust, emitting the bulk of their
radiation at infrared wavelengths. The central kiloparsec in these galaxies
is often completely obscured in the optical regime, where historically most
of our understanding of galaxies and their evolution is obtained. In order
to obtain a complete understanding of the formation, characteristics and
evolution of galaxies, the energetics in the centers of IR-bright galaxies
must be comprehended. Toward this goal, my research utilizes primarily
space-based imaging and spectroscopic observations of IR-bright galaxies
Spitzer, with the ultimate aim
of understanding their role in the formation and evolution of galaxies. A
more detailed description of current projects and links to publications can
be found here.
