This course is a basic to advance
 introduction for the undergraduate students pursuing B.Sc. Geology / Engineering Graduate for Civil and Mining. The term petrology comes from the ancient Greek word Petra “rock” and Logos “explanation” that means the study of rocks and their processes of origin. This course deals with the naturally occurring rocks in field as well as laboratory analysis data that provide sufficient information how they occur in the nature. It gives idea of modern petrological theories which are widely accepted for their origin. The course definitely provides better understanding to students for the processes and principles involved during the origin and evolution of the rocks

He has made significant contributions on the granulite of Rajasthan. He had  to his credit the Research Associateship and the Young Scientist Project Awards of the Council of Scientific and Industrail Research [CSIR] and Department of Science and Technology [DST] New Delhi. He has developed several softwares in diverse field of Earth Science including calculation of Pressure - Temperature and activity of metamorphic minerals. The software’s are using in different universities and research labs. He has published more than fifty research papers in National and International journals.  He joined the Department of Applied Geology, Sagar Vishwavidyalaya in year 1998 as an Assistant Professor and he also served as a Reader in the Department of Geology, Mizoram Central University, Aizawl in year 2004. 

He has been instrumental in the publication of one volume on Metamorphism and Crustal Evolution in year 2005, which contain a wealth of scientific data. He has developed nearly 30 E-content on Petrology (Metamorphic & Igneous) and Mineralogy through EMMRC, Sagar which are already available on CEC-UGC-MHRD, New Delhi web site. He also recorded more than 40 footages on metamorphic and igneous petrology which are continuously telecast on SWAYAMPRABHA National Channels. He has supervised many students for Doctorate Degrees. All are well established in different organization such as NIT, Central University, and Officers in GSI. He is a regular visiting Professor in the Central Department of Geology, Tribhuvan University; Kathmandu Nepal Since 2012.

He is also engaged in Massive Open Online Course (MOOC) on petrology. The course had successfully completed third cycles (Nov. 2016, July, 2017 and July, 2018) with rating of 4.9 out of 5. He had also successfully completed first cycle (July, 2018) MOOC on Metamorphic Petrology for undergraduate students.

Since January 2019,  he is engagged in running the two MOOCs one on Metamorphic Petrology & Thermodynamics for post graduate students and another on Crystallographic & Mineralogy course for undergraduate students.

He has received Life Time Achievement Award-2018 for Outstanding Contribution in the Field of Applied Geology on the Occasion of International Conference on Energing Issue in Agriculture, Environmental & Applied Sciences for Sustainable Development at SHUATS, Allahabad.

 Received Honour  from the Education, Science & Technology Minister, Government of Nepal at Central Department of Geology, Tribhuvan University, Kathmandu, Nepal on 11th, Feb.2019 in recognition to his distinct contribution to Scholarship as a Visiting Professor in the Department.

He is currently teaching metamorphic petrology, igneous petrology and mineralogy in the postgraduate and undergraduate students of the Department of Applied Geology Doctor Harisingh Gour Vishwavidyalaya, Sagar. The thrust area of his research interest is the metamorphic and tectonic evolution of the high-grade gneiss and granulite.
