Biography

Dr. Joykrishna Dey is a Visiting Professor in the Department of Applied Sciences at Rajiv Gandhi National Aviation University (RGNAU). Formerly a professor at the Indian Institute of Technology Kharagpur (IIT Kgp), he is an accomplished academic and practitioner in Physical Chemistry with over 35 years of teaching and research experience. At IIT Kgp, he also held key administrative roles, including Head of the Department of Chemistry and Associate Dean of the Faculty of Science, demonstrating strong leadership and expertise in curriculum development. Dr. Dey’s research primarily focuses on the self-assembly of synthetic chiral surfactants and polymers. A major aspect of his work involves developing stimuli-responsive vesicles and hydrogels for targeted drug and gene delivery. His goal is to prepare stable unilamellar vesicles (ULVs) and hydrogels from amphiphilic molecules for applications in antimicrobial activities, healthcare products, and water pollution control. He is particularly interested in "smart" water-soluble polymers that can change conformation in response to external stimuli. His group pioneered an efficient method for the chiral separation of racemic drugs using micellar electrokinetic capillary chromatography (MECC) with improved resolutions. They are also among the few to demonstrate the role of hydrogen bonding in forming stable vesicles from single-chain amphiphiles, significantly aiding the understanding of gelation processes. Additionally, his research explores protein- and DNA-surfactant interactions, the impact of microenvironments on enzyme catalysis, and excited-state proton and charge transfer processes, which have contributed to the development of laser dyes.
