Academic Qualifications: S. No. Degree Institution Year 1. B.Sc. Banaras Hindu University 1987 2. M.Sc. Banaras Hindu University 1989 3. Ph. D. Banaras Hindu University 1993 Brief writeup on area of specialization/awards/achievements: Recent studies of lightning and thunderstorm activity relate global electric circuit and weather/climate. These all are controlled by the short and long term variations in the solar environment, commonly known as space-weather events. We are mainly working on the study of the processes occurring in the lower atmosphere, ionosphere and magnetosphere of the Earth on the following problems: Awards: Life Member, Indian Physics Association (LM-12777).

Recent studies of lightning and thunderstorm activity relate global electric circuit and weather/climate. These all are controlled by the short and long term variations in the solar environment, commonly known as space-weather events. We are mainly working on the study of the processes occurring in the lower atmosphere, ionosphere and magnetosphere of the Earth on the following problems: Space Weather Studies of Upper Atmosphere. Study of Ionospheric Irregularities using VHF & GPS scintillations. GPS based Total Electron Content (TEC) & Water Vapor content measurements and their variability. Study of VLF Whistler-Mode waves and their generation and propagation mechanisms. Electrodynamics of the Atmosphere-Ionosphere-Magnetosphere. Seismo-electromagnetics to study Earthquake Precursors. Atmospheric studies involving aerosols, dust storms, winter fog, and their radiative and climate effects mainly in Indo-Gangetic basin.
