California Institute of Technology
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 the cosmic microwave and infra-red background radiation. 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.
