Shankar is a researcher currently with the  Research School of Physics of the Australian National University, investigating novel composite nanopore membranes. Using track etch technology and controlled breakdown technique, he is working on an industrially compatible technology for the fabrication of extremely small nanopores of controllable shape and size in a variety of materials. Combining this technology with 2D materials such as Graphene or ultra-thin film deposition enables the fabrication of nanopore membranes with desired functionalities that can be used in medical and biological sensors, ultrafiltration, and lab-on-the-chip applications.
