Born in a family of doctors in India, I grew up looking at the world through a lens of seasoned physicians battling to save lives in resource-poor settings. While the academic in me developed an insatiable curiosity about the biological mechanisms of diseases, the social activist in me realized that exploring drivers of diseases at a population level is important to solve global health problems. My graduate studies at IIT Bombay and University of Cambridge cemented this understanding; extensive field research and work experience with UNICEF impressed upon me the importance of translating research findings into actionable evidence. My PhD seeks to explore the nutritional, lifestyle and metabolic risk factors of diabetes and cardiovascular diseases in South Asians; integrating clinical knowledge, statistics and public health. South Asians, constituting a fourth of the global population, experience a disproportionately high burden of these diseases, aggravated by inequities in biological risk, behavioural factors and access to health services. Through my research I wish to comprehensively examine the importance of modifiable risk factors in mitigating cardiometabolic disease risks in this population and inform country-specific policies and disease prevention strategies.
