Dinesh Kumar is currently working as Professor in the School of Chemical Sciences at the Central University of Gujarat, Gandhinagar, India. Prof. Kumar obtained his master's and Ph.D. degrees in Chemistry from the Department of Chemistry, University of Rajasthan, Jaipur in 2002 and 2006, respectively. Prof. Kumar has received many national and international awards and fellowships. His research interest focuses on the development of capped MNPs, core-shell NPs, and biopolymers incorporated metal oxide-based nanoadsorbents and nanosensors for the removal and the sensing of health hazardous inorganic toxicants like fluoride and heavy metal ions from aqueous media. Prof. Kumar developed hybrid nanomaterials from different biopolymers like pectin, chitin, cellulose and chitosan for water purification. His research interests also focus on the synthesis of supramolecular metal complexes, metal chelates their biological effectiveness. He has authored and co-authored over 90 publications in journals of international repute, one book, over seven dozen book chapters, and 70 presentations/talks at national/international conferences
