Biography

Dr. Sabine El Khoury earned her Ph.D. in Mathematics from the University of Missouri, U.S., in 2007, after which she joined the Department of Mathematics at the American University of Beirut (AUB) as an assistant professor. She later achieved the position of a tenured associate professor at AUB.

At AUB, El Khoury led a team of 30 faculty and staff in a comprehensive redesign of the university’s freshman program. Implementing a "first-year experience" model—based on high-impact practices adopted by U.S. colleges—the redesigned program supported first-year students as they navigated the challenging transition into university life.  

El Khoury’s passion for education ultimately led her to KAUST, where she now works as an instructional professor of applied mathematics. Outside of her core, she also teaches introductory artificial intelligence (AI) courses and math for AI courses.

Research Interests

El Khoury’s research focuses on commutative algebra with having recently a particular emphasis on combinatorial commutative algebra. This field harnesses the power of topology and combinatorics to address complex problems in the theory of syzygies—relationships between the generators of a module—which explores minimal free resolutions over polynomial rings.

El Khoury is actively involved in machine learning and is particularly interested in the mathematical concepts that underlie it.
