About Me

George Shakan

georgeshakan_2k-1720x1118-1

I am a postdoc at CRM working in the research group of Andrew Granville and Dimitris Koukoulopoulos. Until August 2021, I was a postdoct at  the University of Oxford working in the research group of Ben Green. Until May of 2019, I was a PhD student at the University of Illinois at Urbana-Champaign under Kevin Ford. My primary research interests are additive combinatorics, analytic number theory and the intersection of the two. Research has lead me to incidence geometry, exponential sums, probability, harmonic analysis, sieve theory, combinatorics, and elsewhere.
