Hala ElAarag

Professor of Computer Science

Hala ElAarag is the vice president and president-elect of the Consortium of Computer Sciences in College, was a counselor in the Mathematics and Computer Sciences Division of the Council of Undergraduate Research (C.U.R.) from 2011-2014, serves on the technical committee for many international conferences, and reviews for multiple journals. In 2011 and 2012, respectively, she was the vice general chair and general chair of the Society for Modeling and Simulation International (S.C.S.) Spring Simulation Multiconference. ElAarag was the co-general chair of the Communication and Networking Simulation Symposium in 2009, and since 2010 has served as the program chair and as a board member of the Consortium of Computing Sciences in Colleges Southeastern Region.

ElAarag is the 2012 recipient of the S.C.S.' Outstanding Service Award for outstanding and dedicated technical contributions and services to the modeling and computer simulation discipline and to S.C.S. In 2005, she received the Stetson University Research Award, and won the Best Paper Award at the 11th Communication and Networking Symposium (C.N.S. '09).
