**George Shakan**

I currently work as a Data Scientist, researching and developing machine learning models for prediction. Before this, I received my PhD from UIUC under Kevin Ford and then worked as a postdoctoral researcher at the University of Oxford and CRM under Ben Green and Andrew Granville, respectively. 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.
