# Agnikumar G. Vedeshwar

Agnikumar G. Vedeshwar (born July 1959) is an Indian experimental physicist specialized in experimental Condensed matter physics, Solid-state physics, Materials physics, Materials science, Superconductivity and is known for his work in several areas in this field that include: Transport (Hall effect, Thermopower and resistivity) and Optical properties both at low and high temperatures of Semiconductors and High-temperature superconductivity in both bulk and Thin film forms, Thin film fabrication, Vacuum Technology, Photolithography, Electron beam gun, RF Sputtering, device fabrication. He is also known for his work on the analytical techniques: X-ray diffraction, SEM, TEM, ESCA, DTA, EPR and Raman effect in solids, UV/VIS spectroscopy of solids, Thin films for Optical Storage, Surfaces, Interfaces, Nanotechnology, Nanomaterials and Quantum dots, Optical Properties, DFT calculations of Electronic structure, Elastic properties and Optical properties of solids.

## Education and career

Vedeshwar obtained his B.Sc. (1981), M.Sc. (1983), Ph.D. (1988) from the Karnatak University. He was a National Superconductivity Fellow at the Department of Physics, IIT Kanpur during 1988-1990, where he was involved in the research and teaching. He was a National Superconductivity Fellow of Department of Science and Technology of India at the Materials Science Division, I.G.C.A.R., Kalpakkam, during 1990-1993. In 1993, he joined the Department of Physics and Astrophysics, University of Delhi as a permanent faculty and worked as a Lecturer during 1993-1998, as a Senior Lecturer during 1998-2002, as a Reader during 2002-2005 and as an Associate Professor during 2006-2009. Eventually, in 2009, he was appointed as a Full Professor of Physics at the Department of Physics and Astrophysics, University of Delhi where he got promoted as a Senior Professor of Physics in December 2019 and he continues to hold that position till date.
