Dr. Lance J. Twyman serves as Senior Lecturer in Chemistry within the School of Mathematical and Physical Sciences at the University of Sheffield. His academic career spans over two decades at Sheffield since his 2000 appointment, following prior positions at Lancaster University, Oxford, and Cambridge. His research bridges polymer chemistry, supramolecular systems, and biomedical applications.
Dr. Twyman's research focuses on drug delivery systems using dendrimers and hyperbranched polymers to enhance drug solubility, supramolecular chemistry for creating light-harvesting and catalytic structures, biomimetic systems including artificial blood substitutes, and protein binding mechanisms where dendrimer size dictates selective protein interactions. His work demonstrates how macromolecular architecture influences biological function and catalytic activity.
His publication record reveals consistent output in high-impact journals, with recent work emphasizing hyperbranched polymers for anion transport (2021), graphene oxide nanodelivery systems (2016), and porphyrin-cored polymers for photodynamic therapy (2019). These publications demonstrate his interdisciplinary approach connecting polymer chemistry with biomedical applications, particularly in drug delivery and artificial oxygen carriers.
Teaching responsibilities include undergraduate courses in Characterisation, Structure Determination, and Polymer Architectures, plus postgraduate instruction in polymer design. His educational background includes a BSc in Chemistry from King's College London (1991) and PhD from the University of Kent (1995), followed by postdoctoral positions at Cambridge and Oxford.
