I am an astrophysicist with interest in cosmology. My research topics include theoretical cosmology, cosmic microwave background, large scale structure, galaxy clusters, statistical applications and data analysis.  I am involved with several projects. The Atacama Cosmology Telescope (ACT), is an experiment to map the cosmic microwave background (and secondary effects) with arcminute resolution. The associated Southern Cosmology Survey is an NSF funded effort to support ACT research and provides follow up observations ranging from the x-rays to the  infrared.  I am a member of ADEPT -a NASA mission approved for concept study, to measure dark energy- the Dark Energy Survey  -a ground based optical survey to study dark energy- and PAU-BAO, a novel approach to survey the 0.1<z<0.9 universe with narrow band photometry.  I am member of the LSST large scale structure study group.
