'''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 [[Semiconductor]]s 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 film]]s for Optical Storage, Surfaces, Interfaces, [[Nanotechnology]], [[Nanomaterials]] and [[Quantum dot]]s, Optical Properties, DFT calculations of Electronic structure, Elastic properties and Optical properties of solids. <br />
<br />
==Education and career==<br />
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.<ref name="auto1">{{cite web|url=http://www.du.ac.in/du/uploads/departments/faculty_members/Physics_Astrophysics/2755.pdf|format=PDF|title=University Faculty Details Page on DU Web-site : Agnikumar G.
