Our research has following directions:

1. Carbon Nanoscience, Nanotechnology, and Nanomanufacturing

Silicon has been the material of choice in our daily life (world of electronics) since decades. As the future of electronics becomes more explorative, carbon has become an emerging player in micro/nanoelectronics and many more directions. Graphene, Carbon Nanotube, Fullerence - allotropes of carbon and each of which has received a Nobel prize - have brought tremendous opportunities for future. In spite of decade long research, their real presence in applications is still limited. Our group focuses on fundamental as well as applied graphene and carbon nanotube research for not only in electronics but in developing number of other technologies, such as transparent conductors, sensors, and energy devices. We exploit fundamental properties, such as electronic conductivity and surface energy manipulation of these carbon nanomaterials to design the above applications. 'Fundamental physics and Nanomanufacturing from Bottom Up' is the main goal of our this research theme.

2. Low-Dimensional (e.g., 2D, 1D) Materials & Devices

We are keenly interested to study device fabrication and device physics of 2D materials such as molybdenum disulfide/diselenide (MoS₂ and MoSe₂) and 1D nano-wires. We manipulate materials at nanoscale, build nanodevices, and study their underlying physics that are key to future electronics.

3. Interactions of Nano-materials & Biological materials

In this theme of our research, we are interested to understand the interactions between nanomaterials (such as graphene, carbon nanotubes) and biological entity (such as stem cells, biomolecules). We use our fundamental physics knowledge to develop new applications (such as electric field approach to study cellular differentiation).
