Research Interests

• Cosmology, Large-Scale Structure, Dark Energy
• Neutrino Science, Primordial Non-Gaussianity, Lyman-Alpha Forest
• Numerical Simulations, Computational Cosmology
• Large-Volume Surveys (SDSS-IV, DESI, LSST)
• Advanced Statistical Techniques

Major Research Achievements

• Novel state-of-the-art hydrodynamical simulations in massive neutrino, warm dark matter, and dark radiation cosmologies
• World-leading constraints on the absolute neutrino mass scale and on the amount of dark radiation
• Ruled out a sterile neutrino thermalized with active neutrinos at more than 5 sigma - confirming the validity of the LCDM model with the highest CL
• New formulae for the constrained eigenvalues of the initial shear field in the peak/void-patch picture, which unify excursion set and peaks theory of the cosmic web
