Dr. Usha Chandra, retired professor in Physics, emeritus fellow (UGC), and emeritus scientist (CSIR), University of Rajasthan, Jaipur, India, is an experimentalist carrying out research on nanomaterials, minerals, and meteorites under high pressure using Mössbauer spectroscopy. Nanocrystalline perovskites (LaSrMnO) and pyrites (CoFeS2) synthesized using sol-gel process and studied under high pressure using various techniques are the achievements worth mentioning. As an expert in X-ray absorption spectroscopic (XANES, EXAFS) and photoemission (XPS) techniques, she has published several research articles in international journals. She is a member of various professional bodies in this arena. As a member of the American Physical Society (USA.), the Indian Physics Association (India), and the International Advisory Board—Mössbauer Effect Data Center—her contribution to the field is exclusive.
