Health Services Research Unit (HSRU)


Prof Julian Thumboo
Director, Health Services Research Unit &
Vice-Chair for Research, Medicine ACP
Prof Thumboo is a rheumatologist and health services researcher. Aside from being the Director of HSRU, he is also Director of the SingHealth Health Services Research Centre; co-Director of the SingHealth Duke-NUS Health Services Research Institute; Senior Consultant in the Department of Rheumatology and Immunology, SGH; and Vice Chair of Research in Medicine ACP, SGH.

His research aims to improve outcomes for patients through:

(1) introducing patient reported outcomes (PROs) into routine clinical care. This involves improving measurement of PROs and developing innovative methods of administering PROs;

(2) measuring medication adherence and devising interventions to improve adherence. His research interests in Systemic Lupus Erythematosus, Osteoarthritis and Patient Reported Outcomes (including assessment of Health-related Quality of Life in multi-ethnic/linguistic populations and in patients with rheumatic diseases) have resulted in over 170 publications in peer reviewed journals.

Ms Stephanie Fook-Chong
Senior Research Scientist

: 6326 5368
Stephanie has more than 20 years of experience in providing statistical consultation advice and engaging in research collaborations with clinicians and scientists in Singapore.

To date, she has supported numerous studies in multi-disciplinary fields, many with NMRC/SingHealth funding. She has a keen interest in topics such as construction of age-related nomograms and assessment of diagnostic tools. Over a period of eight years, 21 foetal nomograms have been constructed based on data from SGH. These nomograms are of utmost importance for evaluation of the Asian foetus. They are being uploaded into the SGH Obstetrics and Gynaecology ultrasound reporting programme, the Astraia.

As a statistical advisor for Proceedings of Singapore Healthcare, she also regularly reviews articles for this SingHealth peer-reviewed journal.

Dr Li HuiHua
Senior Biostatistician II

: 6576 2620
Huihua has a PhD from NTU, and a MS (Bioinformatics) from Chalmers University of Technology, Sweden. She has applied meta-analysis to genetic association studies to investigate the effects of gene polymorphisms on the development of certain diseases, for example, prostate cancer and breast cancer.

Huihua actively collaborates with clinician scientists in identifying patterns of linkage disequilibrium in different genes among different ethnic groups including Asians and Caucasians, in order to explain variances in genetic association studies and guide the genetic association study. Huihua also has experience in evaluating existing prognostic models and building up new prognostic models to predict survival outcomes of different types of cancer patients.

Dr Hao Ying
Research Fellow

: 6576 2630
Hao Ying has experience in the application of statistical methodology and techniques in translational clinical research and drug discovery, particularly in medical data analysis for the purpose of diagnosis and prognosis in infectious disease and biomarker studies in oncology and diabetes.

She provides statistical consultation and works closely with clinicians and epidemiologists on clinical research. Hao Ying has supported plenty of projects from various research fields such as infectious disease, neurology, urology, neonatology, emergency medicine etc.

She has interests in learning and applying advanced statistical approaches, such as mixed/multilevel models, structural equation modelling, decision tree, Bayesian model, MCMC, to assist clinicians on decision making and disease monitoring and management.
