Dr. D. Prabhakaran is an Associate Professor in the Department of Chemistry, School of Advanced Science at Vellore Institute of Technology (VIT), Vellore, India. He was previously working as a Senior Assistant Professor at VIT (Chennai Campus) from 2010 to 2015. He holds his post-graduation (M.Sc.) degree specialized in Analytical Chemistry from the University of Madras (Guindy Campus), Chennai, India. He completed his doctor of philosophy ( degree in Analytical Chemistry from the Indian Institute of Technology-Madras (IIT-M), Chennai, India, where he received his institute medal for best out-standing thesis in the academic year 2004-2005. He worked as a project associate at IIT-M for a brief period after his Ph.D. and then moved to GE-Plastics, Bengaluru, India, as a post-doctoral researcher. In 2005, he moved to Japan (AIST-Tohoku, Sendai), as a JSPS fellow, to pursue his post-doctoral research in the field of Materials and Analytical Chemistry. In the mid-year of 2007, he was awarded the most coveted and prestigious Alexander von Humboldt fellow to pursue his post-doctoral research at the Technical University of Dortmund, Dortmund, Germany. His current areas of research interest are focused in the field of environmental analytical chemistry especially towards the fabrication of novel silica and polymer monolithic materials for optical ion-sensors. He is also working in the field of heterogeneous photocatalysis towards the development of new-age visible light capture photocatalytic materials for environmental remediation applications.
