Dinesh Kumar is a distinguished faculty member at the School of Chemical Sciences, Central University of Gujarat, Gandhinagar. He is an alumnus of the University of Rajasthan, Jaipur, where he earned his master's and doctoral degrees in Chemistry. Professor Kumar's scholarly achievements have garnered numerous national and international accolades and fellowships, and he has consistently been ranked among the top 2% of scientists globally from 2021 to 2023. His research endeavors are primarily directed toward synthesizing capped magnetic nanoparticles (MNPs), core-shell nanoparticles (NPs), and biopolymers. These include the development of metal oxide-based nanoadsorbents and nanosensors for detecting and removing inorganic toxicants, such as heavy metal ions, from water sources. In the realm of water purification, he has innovated hybrid nanomaterials utilizing various biopolymers—pectin, chitin, cellulose, chitosan—and photocatalytic materials. Additionally, his research extends to creating mixed metal oxide-based hierarchical nanostructures with potential energy applications. Professor Kumar's prolific contributions to science are evidenced by his extensive publication record, which includes over 143 articles in prestigious international journals, four books, more than a hundred book chapters, and approximately 100 presentations at various national and international forums. His work is widely recognized, reflected in his h-index of 38, i10 index of 106, and nearly 5200 citations.Rekha Sharma received her BSc from the University of Rajasthan, Jaipur, in 2007. In 2012, she completed her MSc in Chemistry from Banasthali Vidyapith. She was awarded a PhD in 2019 by the same university under the supervision of Professor Dinesh Kumar.
