Dr. Ali Maalaoui joined the American University of Ras al Khaimah during the fall of 2014 as an assistant professor in the department of mathematics and natural sciences. He received his master’s degree in Tunisia from the University of Tunis, followed by a doctoral degree that he received from the same University in 2010.

Afterward, Dr. Maalaoui moved to the United States to pursue a Ph.D. in mathematics at Rutgers University in New Jersey. After successful completion of the program, he moved to a postdoctoral research position at the University of Basel in Switzerland where he worked with the analysis research group. Before joining AURAK, Dr. Maalaoui served as a teaching assistant at Rutgers University where he had the opportunity to teach many courses and enhance his teaching skills. After moving to Basel, he supported the teaching of a master’s level course in Riemannian geometry. Currently, at AURAK, he teaches undergraduate mathematics courses at all levels.

His research interests involve geometric analysis related to conformal geometry and the study of conformal curvature invariants, as well as CR-geometry and the problem of prescribing the Webster curvature. This field involves studying PDE’s having rigid properties. He is also interested in contact geometry and the study of contact form homology related to the Weinstein conjecture, namely finding periodic orbits of the Reeb vector field. Dr. Maalaoui has more than 15 published papers in prestigious journals and he gave talks at international conferences around the world. He is an avid researcher and is currently collaborating on projects with researchers in various parts of the world, including; United States, Italy, Japan, and Tunisia.
