Dr Varun Rawat earned his MSc Chemistry degree from the University of Delhi and PhD from CSIR-National Chemical Laboratory, India. He then joined the group of Professor Arkadi Vigalok as a PBC postdoctoral fellow, where he worked on the synthesis of calixarene-based complexes. He is currently an Assistant Professor of Chemistry at Amity University Haryana, India, and a visiting scientist at Tel Aviv University, Israel. His research interest includes the synthesis and application of calixarene-based chemosensors and catalysts. He has published over 20 peer-reviewed papers, five patents, and five book chapters. Dr Anirban Das earned his BSc Chemistry (Hons) degree from the University of Delhi, India. He then earned an MS degree in Inorganic Chemistry from the University of Toledo, Ohio, USA (Prof. Mark Mason, 2007), and a PhD in Inorganic Chemistry at University of Idaho, USA (Prof. Chien M Wai, 2012). He thereafter held postdoctoral positions in the United States at Northwestern University (Prof. Eric Weitz, 2012–2014), University of California (Prof. Francisco Zaera, 2014–2015) and at the Wayne State University (Prof. Eranda Nikolla, 2015–2017). Thereafter, he joined as a CSIR Pool Scientist at IIT Delhi, India working with Prof. A. K. Ganguli (2017–2020). He assumed his current position at the Department of Chemistry, Biochemistry and Forensic Sciences at Amity University Haryana as an Associate Professor in 2020. His current interests are broadly in the study of reaction mechanisms and chemical and photoelectrocatalysis using nanomaterials. Dr Chandra Mohan Srivastava earned his M. Tech. in Plastics Engineering and PhD degree from Central Institute of Plastics Engineering & Technology and Delhi Technological University, Delhi respectively. He has worked as a Lecturer at Central Institute of Plastics Engineering & Technology, Ahmedabad. Currently he is an Assistant Professor of Chemistry in Amity School of Applied Sciences, Amity University Haryana, India. His research interests include polymer, biopolymer, nanomaterials for biomedical applications, nanofabrication using electrospinning, and polymer composites. He has published 25 peer-reviewed papers, six patents, and five book chapters.
