Cosmology: studying the accelerated expansion of the universe and finding the cause of this phenomenon by the space-time approach. We are currently focusing on modified gravity (an extension of Einstein's standard theory of gravity) in the context of extra-dimension (space-time has a dimension greater than 4) by working with several models. brane-world such as DGP (model of Dvali-Gabadadze-Porrati group), RS, ...
Particle physics: Researching electromagnetic interactions, weak and strong using standard models and standard model extension models. Specifically, the phenomena studied such as neutrino mass, violation of CPT, Higgs physics, etc. In addition, the application of basic particle models, especially extended particle models (such as 3-3-1, supersymmetric standard model, ...) to explain cosmological phenomena such as baryonic asymmetry, cosmic inflation or cosmic acceleration expansion.
Biophysics: Research focuses on the study of the physical properties of bio-polymers such as proteins and enzymes. To this end, molecular kinetic simulation methods and modeling are used to investigate the structure and function of proteins / enzymes of interest. The method is being used on a variety of issues, including finding drugs to treat Alzheimer's, HIV / AIDS, and cancer.
