I am an associate teaching professor at Carnegie Mellon University Qatar
where I teach courses in mathematics and operations research.
I completed my doctoral studies at
Carnegie Mellon University
where I was in the
ACO
(Algorithms, Combinatorics and Optimization)
program.
My advisor was Oleg Pikhurko.
I then spent one year as a postdoctoral researcher at the Laboratoire d'Informatique Algorithmique: Fondements et Applications
(LIAFA, now IRIF)
at Université Paris Diderot (Paris VII).
After my year in Paris, I taught for two years in the mathematics department at Addis Ababa University
before coming to my current position in Doha, Qatar.
