Career Brief

Career  Brief


I earned my PhD in Physical Chemistry in 2009 under the direction of Profs Ranjit Biswas and Jaydeb Chakrabarti at S. N. Bose National Centre for Basic Sciences, Kolkata (Jadavpur University), India. I continued my postdoctoral research in the same research institute for nearly one and a half years. I joined the laboratory of Prof. Jong Seung Kim at Korea University in Korea, as a Research Professor in 2010 and worked for three years. I am currently an Assistant Professor of Chemistry at Vel Tech Dr. RR & Dr. SR Technical University, Chennai-62, India. I have co-authored 31 scientific publications in reputed international journals. My research includes studying medium dynamics and charge transfer reactions in complex media with the help of advanced spectroscopic techniques, electrochemistry, computational supramolecular chemistry, developing sensor materials for clinically important analytes
