He also holds a Post-Graduate Certificate in Clinical Research from Harvard Medical School, USA. Current research focuses on the genetics of metabolic traits (type 2 diabetes, gestational diabetes, obesity, and cardiovascular disease) using association analyses and different genome sequence approaches. The genetic basis of developing complications of diabetes, in particular diabetic kidney disease (DKD) is also under investigation. His research includes analysis of clinical data and integration with the genetic studies.
