S. Mark Ammons
Hubble Fellow
Ph.D., 2009, University of California, Santa Cruz
http://www.u.arizona.edu/~ammons81/
Areas of Interest: Active Galactic Nuclei hosts, stellar population analysis, Adaptive Optics Instrumentation
Using the Hubble Space Telescope and Laser Guide Star Adaptive Optics, Mark studies the colors and stellar populations of Active Galactic Nuclei (AGN) hosts at high redshift to understand the nature of AGN-driven feedback. He also researches AO technologies that will enable diffraction-limited imaging and spectroscopy at visible wavelengths on large telescopes.

Michael Cooper
Spitzer Fellow
Ph.D. 2007, University of California, Berkeley
http://juno.as.arizona.edu/~cooper/
Areas of Interest: Extragalactic Astronomy and Cosmology
Michael's research addresses questions related to galaxy formation and evolution, with particular interest in the role of environment in establishing the population of galaxies observed locally and at higher redshifts. He is involved in the DEEP2 and DEEP3 Galaxy Redshift Surveys, as well as a variety of other projects ranging from x-ray to millimeter wavelengths.
Jennifer Donley
Ph.D., 2009, University of Arizona

Andrew Marble
Ph.D., 2007, University of Arizona
Areas of Interest:Extragalactic Astronomy and Cosmology Galactic Astronomy and Star Formation Astronomy Education
Andy's time is divided between the LVL (Local Volume Legacy) and SAGE (Surveying the Agents of a Galaxy's Evolution) projects. He is investigating aromatic emission in nearby galaxies using, primarily, data from the Spitzer Space Telescope. He is also involved in studies of quasars and the Lyman-alpha forest.
Casey Meakin
Ph.D., 2006, University of Arizona
Areas of Interest: Stellar Astronomy
Casey's research is focused on better understanding the magneto-hydrodynamics of stellar interiors. His research approach draws heavily on 3D simulations of stellar interiors, including improved models of stellar evolution and Type II supernova progenitors.
Peter Milne
Ph.D.,
Areas of Interest: Galactic Astronomy and Star Formation
Peter studies the optical counterparts of Gamma Ray Bursts. He is a co-investigator on the Super-LOTIS (Livermore Optical Transient Imaging System), a robotic telescope that searches for these objects. He also works in the emerging field of positron astrophysics.
Ben Oppenheimer
Ph.D.
http://luca.as.arizona.edu/~oppen/
Areas of Interest: Extragalactic Astronomy and Cosmology; Theoretical Astrophysics; Stellar Astronomy
Ben is working with Romeel Davé on the enrichment of the intergalactic medium and the connection to galaxy formation, using cosmological hydrodynamic stimulations.
Yong Shi
Ph.D. 2008, University of Arizona
http://cztsy.as.arizona.edu/~yong/
Areas of Interest: Extragalactic Astronomy and Cosmology
Yong's research focuses on the massive black holes and their links to galaxy evolution. He is also working on galaxy morphologies to understand the role of galaxy mergers in galaxy evolution.
Dean Townsley
Bart Bok Fellow
Ph.D., 2004, The University of California, Santa Barbara
http://variable.as.arizona.edu
Areas of Interest: Stellar Astrophysics
Dean uses hydrodynamic simulations to study the explosive nuclear events which occur in accreting white dwarf binaries, including thermonuclear Supernovae (Type Ia) and surface runaways (Classical Novae). He is also keenly interested in the formation and evolution of mass-transferring compact binary star systems containing white dwarfs and the physics which governs their varied phenomenology.
Huirong Yan
Theoretical Astrophysics Program Fellow
Ph.D.,
Areas of Interest: Theoretical Astrophysics
Huirong studies ISM theory. She has been doing research on cosmic ray transport and acceleration in MHD turbulence, solar energetic particles, supernovae remnants, developing new diagnostics for astrophysical magnetic fields, and dust dynamics.
Yujin Yang
Ph.D.,
Areas of Interest: Extragalactic Astronomy and Cosmology
Yujin is working with Ann Zabludoff on extended Ly-α imaging with HST of poststarburst (or E/A) galaxies.
