Senior Postdoctoral Fellow
I am an experimental astrophysicist in the Caltech Experimental Cosmology Group whose scientific background and interests are centered on cosmological observations including studies of diffuse radiation in the cosmos, including the cosmic microwave and infra-red backgrounds. Currently, my focus is on the epoch of reionization, secondary anisotropies in the cosmic microwave background, and the history of the star formation in the Universe. I have extensive experience with instrumentation, observation and data analysis throughout the electromagnetic spectrum from the optical to the radio, with particular emphasis on the infra-red and sub-mm/mm regimes. I am currently involved in a number of projects in a variety of roles, ranging from technology development to the scientific interpretation of data from mature instruments. On this page you can find information about the science I am currently working on, a list of projects, and some interesting links at the bottom.
