Overview
My research is driven by the exciting prospects of extracting detailed information about our Universe from observations of the cosmic microwave background (CMB), exploiting both its anisotropies and frequency spectrum. Through my work I became a leading expert on cosmological recombination physics, CMB spectral distortions caused by early-energy release, and the Sunyaev-Zeldovich (SZ) effect. I am the author of several software packages (CosmoRec, CosmoTherm, CosmoSpec and SZpack) that allow precise computations of unique signals from the early Universe.
Research interests
My main research interests include Cosmic Microwave Background science (CMB spectral distortions; cosmological recombination; cosmological parameter estimation; Sunyaev-Zeldovich effect), atomic physics (two-photon transitions and Raman scattering; helium physics; collisional processes), radiative transfer (Lyman-α; line feedback; electron scattering), and high energy processes in the early Universe (energy transfer to the IGM by annihilating dark matter and decaying relict particles; thermalization physics; double Compton).
