Profile

Previously to joining the Department of Material Science and Engineering as Professor of Biomaterials, I was Professor at the School of Life Sciences, University of Westminster, London. I am also Visiting Professor at the National Heart and Lung Institute, Faculty of Medicine, Imperial College London.

I was awarded the prestigious Inlaks Scholarship and the Overseas Research Students Award to study for my PhD at the University of Cambridge. During my time at Cambridge, I was awarded the Churchill College Scholarship, the Lundgren Scholarship, Leche Trust Scholarship and the Cambridge University Philosophical Society Fellowship Award.

My PhD at the Department of Biochemistry was on a B12-dependent enzyme, methylmalonyl-CoA mutase. My postdoctoral work was at the University of Minnesota, USA, at the Bioprocess Technology Institute, where I worked on fatty acid biosynthesis.

Subsequently, I taught at the Indian Institute of Technology, India, for four years as an Assistant Professor. During this time I worked actively on the production of biodegradable polymers from Streptomyces.

I was at the University of Westminster from 2000 until August 2019, where I was the Research Director of the School of Life Sciences and led the Applied Biotechnology Research Group.

I have published over 100 papers in high ‘Impact Factor’ journals such as Biomaterials, Biomacromolecules, Journal of Royal Society Interface, Acta Biomaterialia and ACS Applied Materials Interfaces, and have presented my work at numerous international conferences.

Research interests

Natural Polymers of bacterial origin and their use in medical and environmentally friendly applications.

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.

Her work has been funded by the EPSRC, BHF, EU, DuPont, 3D BIONET (MRC), CYCLOPS (EPSRC) and WESTFOCUS, London. Professor Roy has been the scientific coordinator of two large EU projects REBIOSTENT, worth 4.9 million Euros with 14 consortium members and HYMEDPOLY, worth 3.5 million Euros with 12 consortium members. She was also the work package leader of another large EU FP7 project, NEURIMP, worth 4.4 million Euros with 8 consortium members.

Currently, she is work package leader in the H2020: BBI/JU project POLYBIOSKIN worth 3 million Euros with 12 consortium members. All four projects involve the use of PHAs for medical applications, drug eluting biodegradable stents, nerve guidance conduits, antibacterial polymers and wound healing. She is co-PI in the BHF funded Cardiovascular Regenerative Medicine Centre led by Imperial College London. She has received EPSRC funding for the development of smart wound healing patches (CYCLOPS) and drug eluting biodegradable stents.

She was awarded the ICURe, Innovation to Commercialisation, grant worth £34,905 from Innovate UK for exploring the commercial potential of Biobased Plastics for Medical Applications. She has an ongoing UKERI project on the development of a 3D disease model for cancer. She has been awarded a H2020: BBI/JU grant, ECOAT, where for the first time she will be exploring the green and environmentally friendly aspect of the PHAs and bacterial cellulose for the development of eco-sustainable multifunctional bio-based coatings with enhanced performance and end of life options. This project is worth 4.6 million and includes 16 partners.

Finally, her most recent grant is from the 3D BIONET and involves the development of 3D cardiac tissue model and includes mathematical modelling in collaboration with the University of Oxford and Imperial College London.
