The primary aim of his research is to understand the genetic basis of complex neurological disorders, with a special emphasis on dementia, stroke and cerebral small vessel disease. He uses approaches starting from candidate genes, genome wide association studies to whole genome sequencing using NGS platforms to identify rare and common genetic variants in genes responsible for complex neurological disorders.

He has been leading large scale genome wide association studies and trans-ethnic meta-analysis as part of collaboration within the CHARGE consortium and other large consortia.

Currently he is exploring ways to use NGS methods to understand genetic variations leading to dementia in the Indian population.
