معرفی
Alex Krolewski is an AMTD Fellow at the Waterloo Centre for Astrophysics, University of Waterloo, specializing in cosmological research using gravitational lensing of the cosmic microwave background to probe cosmic structure formation and test fundamental physics. His work bridges observational cosmology and large-scale survey data analysis.
His educational background includes a PhD in Astrophysics from the University of California, Berkeley (2015-2020).
Krolewski's research focuses on mapping cosmic structure through CMB lensing, with additional expertise in Sunyaev-Zel'dovich effects, galaxy evolution, and synergistic analyses of photometric/spectroscopic datasets. He actively investigates the intergalactic medium and develops methodologies for combining multi-wavelength survey data to constrain cosmological parameters and test gravity on cosmological scales.
Analysis of his 15 most recent publications (2022-2023) reveals a dominant focus on cross-correlation techniques between galaxy surveys (DESI, unWISE) and CMB lensing data, with significant contributions to cosmological simulation frameworks like AbacusSummit. His work consistently addresses dark energy constraints, structure growth measurements, and systematic error mitigation in next-generation surveys.
He maintains active roles in three major international collaborations: the Dark Energy Spectroscopic Instrument (DESI) for galaxy mapping, the Simons Observatory for CMB studies, and the CMB Stage-4 (CMB S4) project for precision cosmology. These affiliations position him at the forefront of observational cosmology efforts aimed at resolving fundamental questions about dark energy and cosmic inflation.
