This is a talk given at lunch time, usually in the conference room at noon.
We use recent constraints on the star formation rate---halo mass---redshift relation to model the host halo environments where short Gamma-Ray Burst (sGRB) progenitors are created.
One of the expanding fields of exoplanet study is the detailed characterization of exoplanets, including the properties of their atmospheres.
The Lyman-alpha forest absorption at z>2 can, with a sufficient density of background sightlines, be used to create 3D tomographic maps of large-scale structure.
Ironically, while the predictions on the dark side of the cosmological "concordance" model LambdaCDM are well understood theoretically, many open questions in cosmology and galaxy evolution revolve around the difficult physics of the luminous, baryonic matter.
Determining individual ages for large populations of field stars will enhance our understanding of the timescale for Galactic formation, evolution, and enrichment. To further this goal, I have worked on calibrating two important age-diagnostics: rotation and asteroseismology.
One of the most exciting broader applications of the study of gamma-ray bursts is in better understanding the star-formation history of the Universe.
The discovery of thousands of extrasolar planets ranks among the most exciting scientific developments of the past decade.
In the past few years, a large number of extrasolar planets have been detected and the next step is to better characterize these systems.
