Currently my group is exclusively exploring various kinds of layered materials to study fundamental physics as well as to develop novel multifunctional electronic and optoelectronic devices based on layered materials. We are working on the growth of high quality layered materials and their integration in to devices. With the support of IIT Madras (under IOE grant) and other Govt. funding agencies, we have nucleated a research Centre "Centre for 2D Materials Research and Innovations" at IIT Madras. Key research activities of this center are:

1. Growth of high quality layered materials (TMDCs, h-BN)
2. Development of energy efficient memristors for future electronics
3. Exploring excitonic physics in layered materials and their heterostructures
4. Investigating carrier transport in layered materials and their heterostructures
