"Our discipline, the science of information and computation, is important, not only because of the multitude of useful applications it offers to today's society, but more crucially owing to the fundamental role it plays in unraveling the mysteries of the universe in which we live."

Selim G. Akl is a professor at Queen's University in the School of Computing, where he leads the Parallel and Unconventional Computation Group. His research interests are primarily in the area of algorithm design and analysis, in particular for problems in parallel computing and unconventional computation.


Dr. Akl is Honourary Editor of Parallel Processing Letters (World Scientific Publishing, since 2017, and previously Editor in Chief of the same journal, 2006 - 2017, and a Regional Editor, 1991 - 2006), an Editorial Board Member of International Journal of Parallel, Emergent, and Distributed Systems (Taylor and Francis; 2004 -), International Journal of Unconventional Computing (Old City Publishing; 2011 -), and Communications in Applied Geometry (Research India Publications; 2006 -), an Area Editor (Unconventional Computation) of Scalable Computing and Communications (Springer; 2012 - ), a Founding Editorial Board Member of International Journal of High Performance Computing and Networking (Inderscience Publishers; 2003 -), and a past editor of Journal of Cryptology (Springer-Verlag; 1988 - 1991), Information Processing Letters (North-Holland; 1989 - 1999), Parallel Algorithms and Applications (Taylor and Francis; 1991 - 2004), and Computational Geometry (Elsevier; 1993 - 2017).

Dr. Akl was winner in 2004 and 2007 of the Howard Staveley Award for Teaching Excellence. He received the Queen's University Prize for Excellence in Research in 2005 and the Queen's University Award for Excellence in Graduate Supervision in 2012. He served as Director of the Queen's School of Computing (2007 - 2017). In 2018, Dr. Akl was the recipient of a CS-Can/Info-Can Lifetime Achievement Award in Computer Science and in 2020 the Queen's University Distinguished Service Award. In 2024, Dr. Akl was honored as an Inaugural Highly Ranked Scholar by ScholarGPS. The citation reads: "Congratulations on being named an inaugural Highly Ranked Scholar by ScholarGPS. Dear Dr. Akl, ScholarGPS celebrates Highly Ranked Scholars™ for their exceptional performance in various Fields, Disciplines, and Specialties. Your prolific publication record, the high impact of your work, and the outstanding quality of your scholarly contributions have placed you in the top 0.05% of all scholars worldwide."
