Research Interest

Prof Graves is currently working on projects about the economic value of innovations in hospital-based services such as programmes to reduce risk of healthcare acquired infections, different approaches to testing cardiology outpatients and alternate treatment approaches for treating complex coronary artery disease. He is leading a qualitative study on why doctors believe non-beneficial treatments happen at the end of life. He is collaborating across all clusters to quantify the economic costs of chronic wounds to Singapore. And there are other projects on screening for paediatric genetic diseases, whether selective termination of resuscitation prehospital is a feasible and cost-effective policy and a project on inappropriate nephrotoxic Non-Steroidal Anti-Inflammatory Drug in Diabetics, Elderly and Renal impairment. He is developing a Graduate Certificate Programme in Health Services Innovation to be launched at Duke-NUS in 2020/21.
