Welcome!  I am an instrument scientist at the Space Telescope Science Institute, working on the  James Webb Space Telescope (JWST).    I work on the NIRSpec team, helping to develop the ground system that will allow users to design observations for the first slit-mask based multi-object spectrograph in space.  My research interests are in the area of galaxy evolution, and I am most excited by spectroscopic observations that help us understand the properties of stars, dust, and gas in the Universe.   Some of the most important astrophysics that shaped our local neighborhood happened in faint, distant galaxies that are hard to detect and even harder to study in detail.  Hence, my most recent and exciting projects have relied on special populations of nearby objects that look a lot like the most distant galaxies ever observed.  These galaxies are providing us with an early glimpse of what we might see with JWST and NIRSpec.  You can read more about these galaxies here.
