PRINCIPAL INVESTIGATOR

Dr Chew Han Shi Jocelyn

Assistant Professor and Clinician Scientist at the National University of Singapore. Studies digital phenotyping, behavioral science, and preventive cardiology to identify early cardiometabolic risk signals and support sustainable behavior change.

Dr. Chew completed her PhD at the Chinese University of Hong Kong, becoming the youngest nurse in Singapore to obtain a PhD. Dr. Chew is also the first nurse to have received training in the Stanford Biodesign methodology as a Singapore Biodesign Innovation Fellow (FY23/24), which included immersion at regional and global centres such as Beijing and the United States

We Hope to Create an Ecosystem for Innovation : Assistant Professor Jocelyn Chew s Vision for Nursing Excellence
"We Hope to Create an Ecosystem for Innovation": Assistant Professor Jocelyn Chew's Vision for Nursing Excellence

Assistant Professor Jocelyn Chew stands out as a pioneer who’s transforming healthcare through technology and behavioural science. The youngest nurse in Singapore to obtain a PhD, A/Prof Chew’s innovative approach to obesity management is redefining how we address one of Singapore’s most pressing health challenges. Her revolutionary app called eTRIP (Eating Trigger-Response Inhibition Program), which is currently being rebranded and renamed to ME (Mindful Eating), uses Artificial Intelligence (AI) to predict and prevent dietary triggers, potentially impacting thousands of patients struggling with excess adiposity and cardiometabolic diseases.
