He has more than 3 years of experience in geotechnical studies, data acquisition, data processing, geological interpretation of magneto telluric and various magnetometers data carried out at Wadia Institute of Himalayan Geology, Dehradun. He joined NIRM in 2008. He has developed the expertise in the field of active fault studies, paleo seismology and engineering geological studies. He has received various appreciation letters from various national and international agencies for his work done in the field of active fault studies and engineering geological studies. He obtained his Ph.D from VIT, University, Vellore in 2017. He has authored over 18 papers, and published in journals and conference proceedings (National & International)
She holds M.Sc (2006) in Geology, M.Phil (2007) in Geology and P.hD (2015) in Geology from University of Madras. Dr. Divyalakshmi K. S was Junior Research fellow in University of Madras. She completed her PhD in Tsunami Threat Assessment by Numerical Modelling and GIS. After joining NIRM in 2008 she concentrated in application of Remote Sensing & GIS for the geological investigations mainly active fault studies for critical civil structures. She is having 11 papers/abstracts in her credit. She presented papers in international (China) and national conferences.
Specialization: Microseismic data acquisition, processing and Interpretation
Research Interest: Application of Microseismics for tunnel, dam, hydrocarbon reservoir and mine monitoring. Brief Research Activity: Presently I am working on stability monitoring of powerhouse of Tala hydropower project and Tapovan Vishnugad hydropower project using microseismic monitoring technique. The powerhouse of THP has suffered rock engineering problems mainly the failure of Rockbolts. Microseismic monitoring at TVHPP is an attempt to correlate the micro-crack locations, probable failure zone of rock mass at different locations of powerhouse and stability of the powerhouse.
