Research and Scholarly Activity

Professor Drekic's research innovatively combines the use of stochastic techniques with advanced computational methods to analyze mathematical problems arising in various applications. He has co-authored over 30 articles, and has published in key journals across several disciplines, including actuarial science, operations research, and statistics. His work has garnered particular attention in the fields of applied probability, insurance risk/ruin theory, and queueing theory. Over the past several years, Professor Drekic has been developing computationally tractable procedures for calculating the probability distributions of fundamental ruin-related quantities of interest, including the time of ruin, the surplus immediately prior to ruin, and the deficit at ruin. In addition, he has been a major proponent of the use of phase-type distributions to model claim sizes and/or interclaim times, as these distributions are one of the most general classes of distributions permitting a Markovian interpretation, and they provide a unified treatment for many classical results in ruin theory.

Biography

Professor Drekic is an Associate Professor in the Department of Statistics and Actuarial Science at the University of Waterloo. He joined the department in 2000 and has taught a variety of courses in actuarial science, mathematics, and statistics. He received his B.A. with honours in mathematics and statistics from the University of Windsor in 1994. A year later, he received his M.Sc. degree in statistics from the University of Windsor. In 1999, he completed his dissertation ("Methods to Reduce Delay in Preemptive Priority Queues") to earn his Ph.D. in statistics from the University of Western Ontario.

Over the last decade, Professor Drekic has been actively involved in the Canadian Operational Research Society (CORS). He took over the editorial duties of the Society's newsletter, the CORS Bulletin, in 1998. He held this position for four years before becoming an executive councillor in 2002. This was then followed by a nomination to vice president, and finally, to the position of president which he held in 2005-2006. In addition, Professor Drekic became an elected member of the International Statistical Institute in 2005. (more and Association Memberships)
