I am trained in Medicine (MBBS and MD in Community Medicine from the University of Delhi, India) and Public Health (MPH from Harvard University, USA). I am currently working at Duke-NUS Medical School, Singapore as Assistant Professor at the Program in Health Services and Systems Research (HSSR) and Head of Research at the Centre for Ageing Research and Education (CARE) . Prior to joining Duke-NUS Medical School in 2008, I worked at Maulana Azad Medical College, Delhi, India, and Duke University, USA. My research focuses on the vulnerability – i.e., increased risk of adverse outcomes – associated with ageing. Within this area, my research agenda is to develop an evidence base that enables understanding, measurement and alleviation of vulnerability, resulting from physical, psychological, social and health service factors, among older adults in Singapore and other Asian countries.
