Research
At the South Pole.
I am an experimental cosmologist and mm-wavelength astronomer whose research focuses on studies of structure formation, and measurements of fine-scale cosmic microwave background (CMB) temperature and polarization anisotropy.

I am interested in the following questions: What is the nature of dark energy? What is the energy scale of Inflation? What is the mass of the neutrino? What was the nature of the first stars, galaxies, and active galactic nuclei in the universe? How did they affect the growth of cosmic structures?
