Our research explores the frontiers of theoretical particle physics, with a strong emphasis on physics beyond the Standard Model. We construct and analyze models of new particles and interactions, investigate mechanisms for neutrino mass generation, and study phenomena ranging from dark matter and neutrino oscillations to extended gauge sectors, Higgs dynamics, and potential collider signatures of new physics. Our work combines high-precision analytical and numerical methods with detailed phenomenological studies, providing predictions for current and future experiments—including the LHC and next-generation colliders—and forging robust connections between fundamental theory and experimentally testable signals.
