Dr. Afsar Ahmed | Materials Science | Best Researcher Award

Saha Institute of Nuclear Physics, India

Dr. Afsar Ahmed is a promising researcher in condensed matter physics, currently pursuing his Ph.D. at the Condensed Matter Physics Division, Saha Institute of Nuclear Physics, Kolkata (2019–2025) under the guidance of Prof. Indranil Das. He completed his M.Sc. (2017) and B.Sc. (2015) in Physics from Aligarh Muslim University, India, both with first-class distinction. His professional experience encompasses extensive research in magnetic materials, magnetocaloric effects, magnetotransport phenomena, anomalous and topological Hall effects, spintronics, and skyrmions, with a Ph.D. thesis focused on non-collinear spin-induced magnetic and transport properties in intermetallic compounds, exploring the coexistence of real-space and momentum-space topologies in systems like inverse Heusler alloys, β-Mn, and layered magnets. Dr. Ahmed has authored 12 publications in reputed journals including Advanced Functional Materials, Physical Review B, and Journal of Physics: Condensed Matter, with 32 citations and an h-index of 3, and presented his work at leading national conferences such as DAESSPS, QMAT, SMS, and ICBEC. His research skills include polycrystalline and single-crystal sample preparation, thin-film deposition (PLD, sputtering), device fabrication, X-ray diffraction (Rigaku TTRAX-III), TEM-EDX, SQUID-VSM, PPMS, and customized cryogenic setups (9 T, 2 K), supported by proficiency in Origin, FullProf, Vesta, Python, LabVIEW, LaTeX, and Fortran-77. Dr. Ahmed has been recognized through merit scholarships, and has qualified competitive exams including GATE, NET, JEST, and WBSET. His awards and honors highlight his academic excellence and commitment to research. With a strong academic foundation, robust publication record, diverse research skills, and active engagement in the scientific community, Dr. Afsar Ahmed is well-positioned to advance impactful research in quantum and topological materials, contribute to international collaborations, and mentor future generations of scientists.
