  ● The identification of various combinatorial and algebraic methods for constructing infinite families of expander graphs. This leads to not only construct expander families of d-regular graphs but also the first one of semi-regular graphs.● The construction of several new infinite classes of integral graphs either by computing their spectrum or by using the newly defined graph operations like the generalized replacement product.● A sufficient condition for Cayley graphs to be Ramanujan is proved. Moreover, a necessary and sufficient condition for Cayley graphs to be strongly regular is presented.● Several results concerning spectral hypergraph theory are revealed. These results can be considered as generalizations to their corresponding ones for the case of graphs. Also, the different isomorphic relations between the Cayley graphs and other alternative ones defined from groups are identified.● Many new results concerning the structural properties of certain graphs defined from groups and their graph invariants are revealed, for instance, those regarding the sparsity, the regularity, and the diameter.

  Postdoctoral Researcher

  ● Developed an epidemic model on realistic networks consisting of susceptible and infected individuals and where the geographic coupling is taken into account. The different vaccination strategies are then examined and the optimal one is presented. A scientific article about this subject is submitted to an international journal.● Developing a marine ecosystem model to help study the effects of constructing offshore wind farms in Courseulles-sur-mer, Bay of Seine, English Channel, France. ● Course taught: Combinatorial optimization, tutorial classes TD to the fourth-year Engineer students GM4.

  LIMENGO Colombelles & INSA Rouen

  May 2022 - Dec 2022

  Research Engineer

  ● Developing a mathematical model for a nursing house EHPAD in Normandy. The goal of the code is to generate an optimized flexible schedule.● Identifying the preferences of the client throughout several meetings. To meet their requirements the developed model has more than 100,000 variables and constraints.● Testing the model using the provided data. Most of the constraints relate to French labor law and improving the comfort of the staff.● As the number of variables is significantly higher than ordinary, also, and some of the constraints are known in the scientific literature to be difficult to model, some advanced analytical techniques and solvers (CPLEX and Gurobi) are employed.
