Background

Dr. Amit Patwa joined Navrachana University in October 2017 as an Assistant Professor. Prior to that, he worked as a post-doctoral research fellow in the laboratory of Prof. Mark W. Grinstaff at Boston University, Boston, USA. He was involved in synthesis, characterization and purification of i) contrast agent for sensitive and quantitative cartilage imaging, ii) polymer and polymeric hydrogel for biomedical applications, iii) PhotoresponsiveCrosslinker for light-induced cleavage and biomedical release application. As post-doctoral research fellow in the laboratory of Prof. Philippe Barthélémy at INSERM, France, he was involved in three different projects. His post-doctoral research work involve molecular recognition and the use of bio-inspired amphiphiles (e.g. Glycosylated Nucleoside Lipids (GNLs), Locked Nucleic Acid (LNA)-based nucleolipids, oligonucleotides-based nucleolipids, etc.) to create novel supramolecular assemblies for multiple applications ranging from molecular building blocks for self-assemblies, to nucleic acids imaging to drug or biomolecule delivery systems. During the course of his doctoral research (under the guidance of Prof. Krishna. N. Ganesh and Vaijayanti. A. Kumar at NCL), he was involved in the studies towards the design, synthesis and X-ray crystal structure studies of ferrocene-nucleobase conjugates.The results are interesting from the point of understanding and engineering supramolecular assemblies through rational design of base pairing patterns. Before his doctoral research, he was working as Project Assistant in polymer chemistry division. The objective of the project was to provide a narrow polydispersity polymer with photo initiation at room temperature and providing controlled/“living” radical polymerization utilizing visible light thereby avoiding the use of free radical initiator. During this period, experience in synthetic organic chemistry and photochemical polymerization using synthesized initiating system were gained. Immediate after his master’s degree, he was working in a company “Synth Services”- A custom manufacturer of specialty chemicals and drug intermediates. During this period, he gained experience in pure synthetic organic chemistry. During his tenure, he had an opportunity to work in a process development plant where he gained experience in high vacuum distillation and handling of hazardous chemicals on kilogram scale. With these experiences, he now describes himself as a synthetic organic chemist who is keen to understand the biochemical processes in the living organism with the knowledge of bio-organic chemistry.

Research Vision

He gained extensive research experience (more than 14 years) in the field of synthetic organic chemistry, nucleic acid chemistry, molecular recognition and supramolecular chemistry, bio-organic chemistry. Over the years, his research approaches have been experiencing transformations from pure synthetic organic chemistry to bioorganic chemistry to nucleic acid chemistry. Understanding the momentousness of present research scenario, he developed a strong interest in interdisciplinary research that will provide scope for diversity of experimental and intellectual approaches that include: synthetic organic chemistry, bioorganic chemistry, molecular recognition and supramolecular chemistry. His basic research question has always been to develop a contrivance for better understanding of biochemical processes in the living organism to address questions of importance in biology and medicine. His involvement as research fellow at NCL and postdoctoral fellow at INSERM and Boston University has given him ample opportunities to interact with several scientists in India, France, UK and USA. This has immensely contributed to hi scientific development. In the near future, he would like to conduct an interdisciplinary research collaborating with these scientific partners in addition to new collaborators. His research vision calls for the development of a laboratory where synthesis and application of bio-inspired molecules will be the central theme. Research demands effective communication with the scientific community and stakeholders. Therefore, he looks forward to publishing his research-team’s work in high-impact journals.

 

Teaching

Professor Amit Patwa teaches Organic Chemistry and related subjects to Science Post graduate and undergraduate students (MSc and BSc). His teaching philosophy can better be described as a philosophy of learning. Therefore, it is much effective in teaching the students how to learn, rather than giving mere facts. Learning through active interaction between an instructor and a student is a part of teaching. Thus, his goal is to ensure students have a better understanding of basic concepts, theories and practical knowledge so that they may apply this information to their future research or professional activities.
