Dr. Dushyant C. Kothari is a Professor of Physics at the University of Mumbai, India. He has had association with the Istituto per la Recerca Scientifica e Tecnologica, Trento, (Italy) and University of Trento as Guest Scientist (1988-1990) and Visiting Professor (1991-94). He has worked as General Manager (R&D) and Vice President (Technology) at Multi-arc India Ltd (1997-1999). He is a life-member of Indian Physics Association, Indian Vacuum Society and Materials Research Society of India.

Dr. Kothari has been contributing to the field of Ion Beam modifications since 1976. He is co-author of over 55 refereed research papers in the field. His past contributions include: ion beam treatment on steels to improve wear and corrosion resistance, ion beam assisted deposition, ion beam mixing, PVD coatings and Plasma Nitriding. He has also developed Ion sources, RF accelerating stages and other ancillary equipment for low energy ion accelerators. His interest in fundamental of ion beam interaction with matter includes the studies on radiation induced segregation and radiation damage. Industrial scale process optimization and application engineering of various PVD coatings have been carried out under his supervision. He has lead a team to develop an industrial scale Plasma Nitriding equipment. His present focus is on the Materials for ADSS and Ion beam synthesis of Nano-materials.
