I am an Associate Research Professor in the
Department of Physics and Astronomy at the
Johns Hopkins University. My primary interest
is in cosmology, large-scale structure and galaxy evolution. I
have been focusing on various statistical and computational challenges in astronomy.
Modern detector technology is rapidly changing the way we do science. The large
projects I work on, including the Sloan Digital Sky Survey, pioneered
much of the new methodology, but the transition has been fairly smooth so far. The change with the
next-generation telescopes will not be incremental.
New hardware architectures, new algorithms and new statistical methods will be needed to analyze
the observations of the upcoming surveys, such as the
Large Synoptic Survey Telescope.
It's going to be a very interesting next decade.
Perfect time to be in astronomy!
