Life & Medical Sciences

I am a medical doctor and an epidemiologist. I obtained my PhD (International Health) at Johns Hopkins Univeristy, Baltimore, USA. My main research interest concerns health determinants and how they vary by geography or country income level. In particular, mental disorders and their comorbidity with physical disorders are her primary interest. I conduct multi-country epidemiological studies examining the modifiable risk factors for a wide range of mental and physical disorders with high burden at the population level.


Research interests

I am interested in learning about health determinants and how they vary by geography. In particular, mental disorders and their comorbidity with physical disorders are my primary interest given my clinical experience as a physician and psychiatrist. Most of my research has focused on multi-country epidemiological studies examining the modifiable risk factors of a range of mental and physical disorders with high burden at the population level using large nationally representative datasets predominantly from low- and middle-income countries (LMICs).
