Keduse Worku

I’m Keduse, a third year astrophysics PhD student at Johns Hopkins University advised by Marc Kamionkowski. I’m interested in the intersections of theoretical and observational cosmology. Our recent work probed late-time signatures of relic neutrinos in the non-linear regime through our JAX code Cheetah. I’m also wrapping up another project with JWST observations of gravitationally lensed galaxies during the Epoch of Reionization with Dr. Dan Coe at STScI. I’ve recently started focusing on imprints of early universe physics on 21cm observables.

Before graduate school, I was a Postbaccalaureate researcher within the Princeton Physics Department working with Professor Jo Dunkley on CMB cross correlations with ACT maps in order to improve foreground constraints. I completed my B.S. in Astrophysics at Yale University working in a different subfield, exoplanets, with Professors Greg Laughlin and Songhu Wang, and I had summer cosmology and galaxy formation projects at Flatiron CCA and The Center for Astrophysics - Harvard & Smithsonian.
