Geha Research Group
In the framework of modern cosmology, massive galaxies such as our Milky Way form hierarchically through the merging and accretion of small dwarf galaxies. My research group is interested in the formation, evolution and destruction of dwarf galaxies, ranging from gas-rich dwarf galaxies in isolation, to the least luminous and most dark matter-dominated galaxies in orbit around the Milky Way.
I am co-PI of the SAGA Survey, and creator of the Keck DEIMOS stellar archive.
