Mr. Samwel Mwigeka | Social Sciences | Best Researcher Award

Ruaha Catholic University | Tanzania

Samwel Mwigeka is a Tanzanian academic and researcher specialising in public finance, macroeconomics and econometrics. After completing a B.A. in Economics & Geography at the University of Dar es Salaam and an M.A. in Economics at the same institution, he pursued doctoral studies at Henan University in China. He began his professional career in secondary education before joining Ruaha Catholic University as an Assistant Lecturer in, where he continues to teach and mentor students. His published work examines key issues in Tanzanian economy such as budget deficits and inflation, the crowding–out effect of deficits on private investment  and determinants of foreign direct investment (International Journal of Management and Economics Invention), as well as pricing dynamics in the sharing-economy (Airbnb listings, International Business & Economics Studies). His research interest lies at the intersection of fiscal policy, investment flows and macro-economic stability in developing countries. Although his bibliometric profile presently lists an h-index of 1 and citation count of 15 according to an academic-indexing source, he is actively establishing his scholarly trajectory. He is motivated to advance the quality and impact of research and contribute to policy-relevant economic development in Tanzania and beyond.

Dr. Sohail Ahmad Khan | Mathematics | Young Scientist Award

Quaid I Azam University Islamabad | Pakistan

Dr. Sohail Ahmad Khan is a distinguished researcher in Applied Mathematics with a strong background in Computational Fluid Dynamics, mathematical modeling, and heat and mass transfer. He earned his Ph.D., M.Phil., and M.Sc. in Applied Mathematics from Quaid-i-Azam University, Pakistan. His academic journey reflects a deep commitment to advancing analytical and numerical methods for nonlinear problems in Newtonian and non-Newtonian fluid mechanics.  Dr. Khan’s research primarily focuses on nanofluid flow, entropy generation, magnetohydrodynamics, and thermal analysis using advanced techniques such as the Homotopy Analysis Method, Finite Difference Method, and Keller Box Method. He actively serves as a reviewer for more than 120 high-impact journals and has received multiple international recognitions, including the World’s Top 2% Scientist ranking by Stanford University in 2022 and 2024. His dedication to mathematical innovation and interdisciplinary applications continues to influence modern engineering and physical sciences, contributing significantly to global research on nonlinear transport phenomena and energy optimization.
