I am an experimental astrophysicist in the Department of Astronomy at the University of Arizona. 

My research addresses galaxies and cosmology, even fundamental physics, through a variety of observational tools. I am particularly interested in galaxy clusters and their cosmological applications, galaxy formation in the early universe, and the physics of the supermassive black hole in our galaxy, Sagittarius A*.

To investigate these topics I very often develop new instruments, primarily at centimeter to submillimeter wavelengths.
