Dr. Liliana Braescu
Professor of Mathematics
+ 966 11 215 7978
Dr. Liliana Braescu is an applied mathematician with extensive experience in mathematics, computer science and materials science, currently Professor of Mathematics in the Department of Mathematics & Computer Science at the Alfaisal University. She has performed outstanding interdisciplinary research over a broad range of science and technologies through valuable contributions in developing 2D- and 3D-models of crystals for optical devices including research on the shape stability of silicon single crystals grown from the melt in a vacuum by edge-defined film-fed growth (EFG) method, and modeling of the growth processes for monocrystals by qualitative and numerical studies concerning the determination of the optimal growth process parameters. Productive international collaborations in this regard have been achieved with the Institut National Polytechnique de Grenoble, Science et Ingénierie des Matériaux et Procédés laboratory (NASR grant: Mathematical and computational modelling of crystal growth processes based on capillarity), and Departments of Chemistry & Biochemistry and Physics & Astronomy at the University of Missouri-St Louis (NATO grant: Evaluation and control of impurities in rapid-detection sensors). Dr. Braescu earned her first doctorate in Mathematics (2002) from the West University of Timisoara, Romania. She enjoyed of a rapid evolution in her teaching career, from secondary and high school, up to undergraduate and postgraduate levels at polytechnic and university. She was promoted to Associate Professor in 2006 at West University of Timisoara. In 2011, Dr. Braescu joined to Université du Québec, Institut National de la Recherche Scientifique (INRS), Centre – Énergie Matériaux Télécommunications (EMT) thanks to the Alexander Graham Bell award funded by Natural Science and Engineering Research Council of Canada (NSERC), where she developed more the computational and theoretical knowledge in the area of the synthesis of thin films by different vapour deposition techniques. Simultaneously, she joined to Radiological Technologies University-VT, USA (2012) as Professor of Mathematics being responsible for teaching Advanced Statistical Analysis, Calculus, Multiple Variable Calculus and Applied Mathematics. In 2013, Dr. Liliana Braescu became a Fellow of the International Society for Optics and Photonics (SPIE) for achievements in developing 2D and 3D models of crystals for optical devices.

In order to complement the PhD in Mathematics, with the goal to provide guidance in developing new advanced technological materials, Prof. Braescu is studying more in detail some technologically promising functional materials by doing first-principles density functional theory (DFT) calculations using the projector-augmented wave (PAW) formalism applied to multiferroic thin films. This work is critically important to predict the effects of the strain on the structure and multiferroic properties of epitaxially strained films that are being synthesized and investigated experimentally in INRS-EMT, as well as to explain their thickness dependence and in particular the origin of the critical thickness observed.

Besides the above subjects, Dr. Liliana is interested in expanding her research further being open to whatever opportunities might arise with academic and industrial partners, e.g. materials for energy applications, biotechnology and bioengineering.

Dr.Ali M. Elgindi
Assistant Professor of Mathematics
+ 966 11215 7783
Dr. Ali Elgindi received his PhD in Mathematics from the University of Chicago in 2011. The focus of his thesis was on the properties of real manifolds embedded in complex Euclidean space. In particular, he studied the topological structure of the set complex tangents to embeddings of 3-manifolds into complex 3-space, and also researched regarding the form of the Bishop invariant in this dimension, obtaining a simpler and more applicable formula. His other areas of research include low-dimensional topology, contact structures, and complex differential topology. He is also interested in the theories given by mathematical analysis in finance and the applications of low-dimensional topology to generalized general relativity in physics.

In his spare time, Dr. Ali enjoys cooking, sports such as football and basketball, watching historical movies, and reading. He takes a particular interest in reading meaningful books in philosophy and psychology, and also religion. He also enjoys intellectual debates with friends, seeking knowledge and understanding of the many interesting aspects of the universe and of life.
