About Me
I am Professor of Mining Engineering at the Indian Institute of Technology (Banaras Hindu University), Varanasi, India since 15th May, 2010. I am a fellow of the Institution of Engineers of India and Professional member of the SME, USA. Institute nominated me for MHRD LEAP training in 2018 @IIT, Kanpur and NTU, Singapore. I joined this institute on the 19th March, 1993 as Lecturer in Mining Engineering before that I had had a brief stint with the National Airports Authority of India as an Aerodrome Officer.
Engineering and Technology has to innovate and evolve so that the seven billion odd people could survive on this planet with comfort, dignity, security, thrill and enthusiasm in an eco friendly way. Aware of this responsibility- I am attempting to cater to societal needs through need based research and academic courses and technological solutions in the areas of Mining Engineering. I have been actively researching and consulting in the areas of Numerical modeling in Rock engineering, Environmental Management Capacity Building (EMCB), Subsidence prediction and management, Rock reinforcements, Rock instrumentation, Rock Blasting and fragmentation, Under ground Space Technology, Mine Safety and Legislations and Mine Management. I have completed two Research Projects- one of the World Bank under EMCB and another of the CSIR, Govt of India on Numerical modeling of Jointed Rock-mass. I have guided three doctoral thesis in the area of Rock blasting and Suspended particulate matter dispersion modeling and am guiding nine of them. Under me 34 M Tech theses have been awarded.
I have served as expert in many prestigious Government and Non Government organizations for Doctoral thesis examinations and selection committees.
I have completed  122 technical consultancy reports- where some of my clients included NTPC, Adani Power, CESC, High Court of Allahabad, JITF,  Accountant General of Uttar Pradesh, Coal Mining Conglomerates, Uttar Pradesh Irrigation Department, UPEIDA,  and others.  I have convened many National and International Symposia and edited eight proceedings on various themes. I have published fifty research papers in the International and national Journals and conferences. I have also coordinated many outreach programmes for the field executives of ACC, BHEL, Powergrid, Coal India Ltd. and many others- in the areas of my expertise.
I am quite appreciated as an acclaimed orator. I  have delivered more than 175 invited/expert lectures in the areas of Rock Mechanics, Management, Higher Education, Leadership, Motivation, Literature and Philosophy. Notable ones being keynote lecture at the Indo-Swedish International Philosophical Conference on Practice based Knowledge. I was invited as motivational speaker at the Rotary Club District Conference. I have been regularly contributing as expert speaker at the UGC-Academic Staff College, Banaras Hindu University for University/College faculty members. I have also lectured for the students/ research scholars on current themes.
I have made a humble contribution towards system maintenance and building whenever Institute entrusted me the task. I was the member of the committee that formulated the Post Graduate Ordinances of the IIT(BHU), Varanasi. I was Head, Department of Mining Engineering (23rd April, 2016 to 22nd April, 2019), Chairman, Administrative Monitoring Committee & the Institute Lecture Series, IIT(BHU), Varanasi, Chairman, Admin Reforms Committee, BHU and member, CEP and Conference Committee and Senate Library Committee and the Advisor, Training and Placement of the Institute. I was Coordinator of the Gandhi Technology Alumni Centre, Administrative Warden of the First year students for three years, Member, Careers and Higher Education Committee of the University and the Management Committee of the University Cafeteria and NSS officer.
