My research interests are focused on the following;
My current research projects with aerospace companies (Airbus - Bombardier), require nonlinear multi-scale computational homogenization modeling applying Finite Element to predict the material behavior on the micro-level and the product performance on the macro-level. Developing such multi-scale models is very efficient to understand the load, stress and damage distribution in our design, which makes it an essential tool for design optimization down to the level of yarn structure design. Yet, these multi-scale models are expensive time-wise. To overcome such challenge, I am developing two approaches; first one is to use one of the semi-analytical approaches to analyze the cell on the micro-level at non-critical areas of the composite structure, while using finite element to analyze the cell on the micro-level at critical areas (possible cracks - high stresses). Second approach is to develop a surrogate model that can reflect the model on the cell micro-level and integrate it to the multi-scale FE model, which can be efficient enough to be used in design optimization process.
Predicting damage in composite panels due to manufacturing process is very challenging, and the above developed multi-scale model can include damage in it on the level of matrix and yarn for better simulation results.
During manufacturing simulation using FE, the material of the aircraft panels is assumed to be at zero-stress state. Despite the hot rolling and, cutting and their effect on the microstructure of the material, these effects are ignored in simulations, which makes it very interesting area of research as it also affect the outcome of the riveting process.
Currently, I apply micromechanics to investigate cure of 2-D composite laminates in an Autoclave. My research focuses on using heat convection as a heat source, the next step will be using microwave instead as a heat source.
During my Post Doc position at Delft Technological University at the Aerospace Structure Department. I participated in preparing two research proposals that are related to Thermal protection of re-entry vehicles. One proposal is to simulate the oxidation process of the metallic panels using finite element and its effects on the thermal fatigue and creep processes. Second one is to propose a better mechanical and thermal design of a thermal protection panel for re-entry vehicle. If I have the chance and funds, I will be very interested to approach the first proposal.
During my job with the Egyptian Space program, NARSS - EGYPT. My work was focused on strength analysis of satellite structure under static, dynamic, acoustic, and thermal loads. Due to the fact that loads are stochastic and not deterministic, I did a study in the area of reliability of satellite structures applying stochastic finite element analysis.
I spent 5 years working in Aerospace industry. During that time I was fortunate to conduct a variety of training programs, both for other employees and for our customers. That experience helped me realize my love for teaching. That passion, and an enthusiasm for discovering and sharing new ideas, led me to come to a graduate school so that I could pursue an academic career. I enjoyed my teaching experience at Delft Technical University and Emirates Aviation College, where I found interest in guiding and tutoring the students.

I am enthusiastic about both laboratory-oriented courses and more theoretical courses and think that both have their place in the curriculum. I also enjoy one-on-one teaching and advising.
