Sri Niwas was an elected fellow of all the three major Indian science academies viz.
Sri Niwas, born on 4 July 1946 in Rakhat village of Gorakhpur district, in the Indian state of Uttar Pradesh to Ram Adhar Pandey, did his early schooling at local schools to complete his intermediate course from Board of High School and Intermediate Education Uttar Pradesh before joining Banaras Hindu University for his college education from where he passed BSc hons degree in 1966 and MSc in geophysics in 1968.
Sri Niwas enrolled for doctoral studies at the same university and secured a PhD in 1974 for his thesis, Theoretical treatment of some problems on electrical behavior of layered Earth system.
Sri Niwas served out his entire career at IIT Roorkee, holding such positions as a Lecturer and Reader before superannuating in 2011 as a professor.
Sri Niwas was married to Shashi Kala and the couple had three children.
The researches of Niwas were focused on the geophysical problems with regard to their forward and inverse solutions and his pioneering work assisted in the electrical exploration of groundwater in alluvial terrains.
Sri Niwas proposed models of system matrix function in terms of exponential functions and designed a methodology using singular value decomposition which is reported to have applications in a variety of geological environments.
Sri Niwas's studies have been detailed in several peer-reviewed articles; the online article repository of the Indian Academy of Sciences has listed a number of them.
Sri Niwas guided 12 doctoral and 110 MTech students in their studies.
Sri Niwas's contributions were reported in the establishment of the Department of Geophysics at Kurukshetra University and he was one of the group of academicians who designed a curriculum in geophysics for IIT Roorkee.
Sri Niwas was a life member of the Indian Geological Congress and a member of the faculty of Earth Sciences of the Innovation in Science Pursuit for Inspired Research program of the Department of Science and Technology.
Sri Niwas was involved with the Summer School program of the Science and Engineering Research Council and was a referee of Proceedings in Earth and Planetary Sciences of the Indian Academy of Sciences.
