Mr. Debasis Sahu | Gravitation | Best Researcher Award

Fakir Mohan University | India

Debasis Sahu is a dedicated researcher in astronomy and astrophysics, with a specialised focus on gravitation, cosmology and plasma-cosmology models. He holds an M.Sc. in Physics, followed by a B.Ed. and an M.Phil., and he is currently engaged as a Research Scholar at a university in Odisha. His work explores themes such as the impacts of dynamical dark energy on black-hole dynamics, constraints on black-hole formation from matter-density, helium-abundance and cosmic-microwave-background radiation, and interacting dark-energy models in loop quantum cosmology. His contributions have been recognised with a Best Oral Presentation Award at a cutting-edge frontier-physics conference. His scholarly output includes multiple publications in peer-reviewed journals and conference proceedings, with numerous citations attesting to the influence of his research and a steadily growing h-index. Through his membership of professional bodies such as the Astronomical Society of India, Odisha Physical Society and Odisha Mathematical Society, he remains active in the research community. Looking ahead, he aims to further deepen our understanding of the evolving universe and the role of dark sectors in astrophysical phenomena.
