I am an astronomer at the Space Telescope Science Institute (STScI) located in Baltimore, MD. The STScI is a NASA-funded research center whose mission currently involves supporting scientific exploration with the Hubble Space Telescope and preparation for science operations of the James Webb Space Telescope.

My research interests include making observational constraints and discoveries about the formation and evolution of clusters of galaxies, large-scale structure in the cosmos, dark matter and cosmology. I am also interested in the implementation and design of digital sky surveys, future mission concepts for large space telescopes, and data visualization.
