School of Clinical Dentistry Seminar Series

Wednesday 16th October 2019: 1.00-2.00pm

Lecture Theatre 1: School of Clinical Dentistry

Speaker: Professor Ipsita Roy, Department of Materials Science & Engineering, University of Sheffield

Title: ‘Natural Polymers of Bacterial Origin: Potential Biomedical Applications’

Professor Ipsita Roy is an expert in microbial biotechnology, natural biomaterials and their biomedical applications. She has recently joined the Department of Material Science and Engineering, Faculty of Engineering, at the University of Sheffield as Professor of Biomaterials. Previously she was Professor at the School of Life Sciences, University of Westminster, London. She is also Visiting Professor at the National Heart and Lung Institute, Faculty of Medicine, Imperial College London.

Her group is currently focussed on the production of novel Polyhydroxyalkanoates (PHAs), a group of FDA-approved natural polymers and their characterisation. She has pioneered the production of PHAs from Gram positive bacteria which lack immunogenic properties and hence are excellent materials for medical applications. Her group is involved in the application of PHAs in the area of hard tissue engineering, soft tissue engineering, wound healing, drug delivery and medical device development. She has also initiated work with bacterial cellulose and γ-polyglutamic acid, as natural polymers for biomedical applications. PHAs are also environmentally friendly polymers that are biodegradable both in the soil and in the sea. She has recently initiated work related to this aspect of PHAs.

Professor Roy is an excellent speaker who will be covering her work into the manufacture of novel polymers using bacterial cultures. This has relevance not only to our basic scientists (especially the microbiologists, manufacturers, and tissue engineers), but also to those of us with a developing interest in “sustainable dentistry” and the reduction in use of non-degradable single use plastics in surgery and practice.

All welcome.
