Research activities in the Theoretical High Energy Physics Division are grouped into three subdivision:

1. Space-Time and Cosmology focused on the study of alternative gravitational theories and their cosmological consequences, some topic studied such as:
   • Modification of Gravity via Scalar-Vector-Tensor Theory which violates Lorentz invariance, including modified Newtonian dynamics, interactions between scalar field dark energy and cosmic dark matter, Lorentz violations in black holes and gravitational lensing.
   • Alternative cosmological models based on string theory, including the braneworld and gas string cosmology.
2. Field Theory and Mathematical Physics focused on the application of several mathematical techniques to supersymmetric theories, some topic studied such as:
   • The dynamics of solitons in general relativity and field theories, including Ricci’s solitons in Kahler’s manifold and their relationship with cosmology.
   • The dynamics of supersymmetric theories N=1 on the four-dimensional Kaehler-Ricci solitons and their relationship to cosmology.
   • Solitonic solutions such as domain walls and black holes in supersymmetric theory N=2 five dimensions.
3. Nonlinear Dynamics and Computational Systems focused on the study of the application of several mathematical techniques in solving complex system models, some topic studied such as:
   • Chaotic behaviour in both autonomous and nonautonomous systems of first order differential equations.
   • The distribution of protein energy based on the Davydov-Scott model and its relationship to the state of vibrational excitation due to the mechanism of protein folding.
