Das' most recent research interests involve additive manufacturing of graphene, nanotubes and inorganic nanowires for sensing and energy applications such as electrochemical sensing and thermoelectric energy generation. He is keenly interested in studying transport physics in micro/nano-manufactured devices such as transistors with low dimensional channel materials and applying them to various platforms. During his doctorate study, he investigated electrical and electro-thermal transport in nanoelectronic devices such as field effect transistors and graphene-based high-performance transparent conductors. Along with his colleagues, he has coined 'co-percolating transport' and 'super-Joule heating' to understand the electrical properties in multicomponent electronic materials.
