Dr. Sangita Das is working as Newton International Fellow at Durham University, England, United Kingdom. She also works as a visiting professor in the Department of Energy Science in Mahatma Gandhi University, Kerala, India. She received her B. Sc. degree with honors in chemistry in 2008 from the University of Calcutta, Kolkata, West Bengal, India. She obtained her M. Sc. degree in chemistry with organic specialization in 2010 from the same university. She had qualified the all India (CSIR–JRF) NET, and then she joined “The Goswami Group, Department of Chemistry, IIEST for her doctoral work under the supervision of Prof. Shyamaprosad Goswami. She got Ph.D. in 2016. Her areas of research interest include molecular recognition; design of fluorescence chemosensors; and characterization of fluorescence probe (detection of metal ions, anions, reactive oxygen species, nerve gas, and other environmentally hazardous species, etc.); aggregation-induced emission dyes and solid-state emitters, and synthesis of compounds with antidiabetic activity. She is now working as a Newton International Fellow in the United Kingdom. Her current research activities include the development of compounds as HDAC inhibitors, experimental and theoretical investigations of electronic structure of transition metal complexes with redox noninnocent ligands, and computational chemistry (DFT, TDDFT calculations). Professor Sabu Thomas is the Director of Centre for Nanoscience and Nanotechnology, Mahatma Gandhi University, Kottayam, Kerala, India.
