  Academic Identity

Dr. Rama Mohan Kurakalva received M.Sc., and Ph.D., degrees in Analytical Chemistry and Environmental Chemistry from Sri Venkateswara University (SVU) in Tirupati, India.  Dr. Kurakalva is currently working as a Senior Principal Scientist at CSIR-National Geophysical Research Institute (CSIR-NGRI), Hyderabad, India and holds a Professor, the Faculty of Physical Sciences, Academy of Scientific and Innovative Research (AcSIR) @CSIR-NGRI Campus. 

Dr. Kurakalva’s research areas include Environmental GeoChemistry with an emphasis on Environmental pollution assessment and remediation; Environmental fate, behavior, and effects of pollutants. 

He is an expert in studies on remedial technologies in particular on ISCO and Adsorption technologies for the reclamation of subsurface environmental media contaminated with various pollutants. This research involves consideration of the contaminants' physical and chemical properties as well as the biogeochemical process.

Dr. Kurakalva has engaged in various research projects sponsored by different government agencies namely DST, BRNS, and Pollution Control Boards. He had successfully completed International Bilateral Collaborative Research with Russia and Bulgaria which is sponsored by DST from the Indian side.

Dr. Kurakalva is in charge to cater the analysis of various environmental pollutants using GC-MS, ICP-OES, Ion Chromatography, UV-Vis Spectrophotometer, TOC analyzer, etc. He is an expert in developing analytical methodologies for trace-level determination of pesticide residues and trace elements in different environmental samples.
