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 develops the modeling and statistical 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. He utilizes analytic techniques, cosmological simulations, and novel applications of AI.

Prof. Blazek is a member of the Dark Energy Survey, the Rubin Observatory Dark Energy Science Collaboration, and the Roman Space Telescope. 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.
