- My primary research involves Astrophysics from the Moon, consisting of the design of low frequency radio telescopes in lunar orbit and on the farside surface. I am leading NASA-funded mission concept studies for a lunar SmallSat and a farside radio array for Hydrogen Cosmology. This work is funded by a NASA ATP grant, and two NASA mission concept study grants. I also lead a multi-institution team called the Network for Exploration & Space Science with a $3.75 million NASA SSERVI grant. My other research involves observations and numerical simulations of galaxy clusters. The numerical simulations model observations with the NASA Chandra X-ray observatory, and the JLVA and GMRT radio telescopes. Along with graduate students & postdocs, I study the role of shocks and cosmic rays created as clusters merge. This work is currently funded by a NASA ADAP grant.
