Professor S K Sidhu, BDS, MSc, PhD, FICD, MFDSRCS, FADM, SFHEA

Profile

Dr Sidhu obtained her degree in dentistry (BDS) from the National University of Singapore and subsequently did all her postgraduate training in the UK, including a clinical Master’s at the Eastman Dental Institute and a PhD at Guy’s Hospital, University of London. Her dental career began in hospital service and then private practice in Singapore, followed by a shift to an academic career. Her first academic position was at the Faculty of Dentistry, National University of Singapore. This was followed by a stint as an Overseas Visiting Lecturer at Guy’s Hospital in London and then as a Clinical Lecturer at Newcastle University before moving to Queen Mary University of London. She also holds honorary positions at UCL Eastman Dental Institute in London as well as Hokkaido University in Japan.

Dr Sidhu has taught at both undergraduate and postgraduate levels, while maintaining clinical commitments and service within an academic environment. She is on two clinical specialist lists in the UK (Restorative Dentistry and Prosthodontics), and is a member of the pan-London specialist training committee. In addition, she has educational qualifications and received accreditation as a Senior Fellow of the Higher Education Academy in the UK. Dr Sidhu has been appointed as external examiner at all levels (undergraduate, Diploma, Master’s, MPhil, and PhD levels). She has also numerous roles of an advisory and mentoring nature.

Centre: Oral Bioengineering

Teaching

Prof.  Sidhu is involved in undergraduate clinical teaching primarily in Restorative Dentistry. In addition, she contributes to postgraduate clinical and didactic teaching. She is responsible for the Adhesive Module in the Prosthodontics postgraduate programme and previously developed the postgraduate course in Endodontics.

Research

Research Interests:

Dr Sidhu has developed a research profile focussing on dental materials, particularly in adhesive materials, and interfaces. In addition, she has developed her expertise in glass-ionomer materials for which she is well-known. In 2001, Dr Sidhu was awarded the International Association for Dental Research (IADR) Toshio Nakao Fellowship in dental materials science. She has published widely in peer-reviewed journals, served on journal editorial boards and has edited a book titled “Glass-ionomers in dentistry” published by Springer Science. Dr Sidhu has been on funded research sabbaticals to the research centres/laboratories of some of the most highly-regarded researchers in dental materials at universities in the US, Japan and Australia. She has also been appointed as a member of international grant funding and awards committees.

Dr Sidhu has supervised numerous postgraduate research projects at Master’s level as well as PhD research students. She has also examined research theses externally and overseas.
