I am a Staff Member in the Physics Division at Lawrence Livermore National Lab. I use the cosmos to determine the properties of dark matter and nature of dark energy. In particular I use microlensing of Milky Way and Magellanic Cloud stars, as well as weak lensing, X-ray, optical, and spectroscopic observations of merging galaxy clusters to compare dark matter with baryonic matter. I am also a member of the LSST Dark Energy Science Collaboration with a focus on using cosmic shear to constrain the nature of dark energy. Generally I am interested in using statistical methods to enable science at the low signal to noise frontier.
Welcome. Research doesn't leave much time for website design anymore so please forgive the dated material. |
