Abbas Mehrabian awarded a Governor General's Gold Medal

Friday, June 12, 2015
Abbas MehrabianAt the Spring 2015 convocation, Combinatorics and Optimization student Abbas Mehrabian was awarded a Governor General's Gold Medal for high standing academic achievement by a doctoral student. The University of Waterloo awards one such medal each year.
 
Abbas's research interests are in random graphs, extremal graph theory, probabilistic  combinatorics, and their applications in theoretical computer science. His Ph.D. thesis Diameter and Rumor Spreading in Real-World Network Models, was supervised by Professors Joseph Cheriyan and Nick Wormald. The thesis presents an elegant, general framework for proving logarithmic upper bounds on the diameter of random graphs that applies to many models of random graphs including the Webgraph and random Apollonian networks. The thesis also addresses the dynamics of information dissemination in networks, and analyzes the well known push&pull protocols in the context of rumour spreading.
 
Abbas has been remarkably prolific. He has written 23 research articles,
many of which have been published in top journals including
  • Combinatorics, Probability and Computing;
  • SIAM Journal on Discrete Mathematics;
  • ACM Transactions on Algorithms;
  • Journal of Graph Theory;
  • Discrete and Compuational Geometry; and
  • Random Structures and Algorithms.

Two of his articles, on the cops and robbers game, were co-authored with Professor Noga Alon.

During his graduate studies, Abbas organized several reading groups and study groups on advanced research topics. He was a recipient of a Vanier Canada Graduate Scholarship and a two-time recipient of an Ontario Graduate Scholarship. In 2015, he was awarded an NSERC Postdoctoral Fellowship.
