Aravind Vijayaraghavan studies the thinnest material ever made: graphene. He is a Lecturer in Nanomaterials at the University of Manchester and investigates how graphene can be developed for applications in electronics, sensors and biotechnology. He is particularly interested in graphene’s biocompatibility and in integrating or mimicking biological systems with graphene. He has received funding from the Bill and Melinda Gates Foundation to develop a graphene condom. He is a passionate science communicator and won the 2013 Joshua Phillips Award for Innovation in Science Communication.
