Dr. Babu's work spans several key areas:

• Grand Unified Theories (GUTs): Studies of SO(10), SU(5), and E6 unification frameworks.
• Neutrino Physics: Development of models like the Zee-Babu mechanism for neutrino masses and research on oscillations.
• Dark Matter & Cosmology: Proposals for dark matter candidates and connections to inflation and baryogenesis.
• CP Violation & Leptogenesis: Mechanisms for generating matter-antimatter asymmetry.

His recent publications highlight advancements in:

• Spontaneous CP violation in SO(10) (2025)
• Left-right symmetric models for leptogenesis (2025)
• Ultraviolet-completed two-loop neutrino mass models (2025)
• Probing baryon number violation at IceCube and LHC (2024)
• Accidental Peccei-Quinn symmetry for axion models (2024)

Dr. Babu actively collaborates on international initiatives such as the Center for Theoretical Underground Physics (CETUP) and contributed to the Snowmass 2013 Community Planning Study. His lab has mentored numerous graduate and postdoctoral researchers, including Kirtiman Ghosh, Sudip Jana, and Shaikh Saad.
