Shri Krishna Joshi

Shri Krishna Joshi (a.k.a.S. K. Joshi) is an Indian physicist. He was born on June 6, 1935 in the village of Anarpa in Kumaun, Uttarakhand, India.

Joshi received his Ph.D. in Physics from Allahabad University in 1962. Joshi's broad areas of interest are condensed matter and collision processes. His early research was in the study of phonons in metals and insulators. Later, he studied electronic states in disordered systems and electron correlation in narrow band solids. He has also worked on Surface states and Segregation in materials. Joshi conducted studies on excitation and ionization processes in atoms, ions, and molecules. His current research interests lie in strongly correlated electron systems, such as high temperature superconductors, and also in nanotechnology, especially electron transport in quantum dots and nanotubes.

Joshi has supervised the Ph.D. theses of twenty scholars and has published more than 190 research papers. He was Professor of Physics at the Indian Institute of Technology, Roorkee from 1967 to 1986. He was the Director of the National Physical Laboratory from 1986 to 1991. In 1991, he was appointed the Director General of the Indian Council of Scientific and Industrial Research. After retiring in 1995, he was awarded the Sarabhai Research Professorship in Physics. He currently works on condensed matter theory at the National Physical Laboratory in New Delhi.
