About Jonathan Blazek

Prof. Jonathan Blazek works in observational and theoretical cosmology. His primary focus is on understanding the Universe using astronomical surveys that cover large areas of the sky. He works on the analytic modeling and numerical methods necessary to connect these observations to the underlying cosmological model. Of particular focus in his research are applications of galaxy clustering and weak gravitational lensing to map out structure in the Universe.

Prof. Blazek is a member of the Dark Energy Survey and the Vera C. Rubin Observatory Dark Energy Science Collaboration. He is also involved with efforts to combine data sets from multiple different experiments that observe at different wavelengths and use different techniques. This “combined-probe” approach will produce the most informative tests of our cosmological model. Prior to joining Northeastern, Prof. Blazek was a postdoctoral fellow at EPFL in Switzerland and at Ohio State University. He received his Ph.D. from the University of California, Berkeley.

We aim to unravel the mysteries of the Universe, including the nature of dark energy and dark matter, the laws of gravity on the largest scales, and the earliest moments after the Big Bang. To study these topics, we model and analyze observations of galaxies and other astrophysical objects, especially from the Dark Energy Survey (DES) and the upcoming Legacy Survey of Space and Time (LSST) at the Vera Rubin Observatory.
