David's current projects are focusing on the development of scientific analyses for the Dark Energy Survey (DES). The DES is an exciting, broad ground-based optical survey. It will measure cosmological parameters through the use of gravitational lensing, studies of clusters and large scale structure of galaxy populations. Presently David's work is aimed at optimizing the performance of instrument operations and data reduction, and development of scientific analysis techniques usingsimulations, science verification data, and the full survey data set.
