Ashutosh Chilkoti is the Theo Pilkington Professor and the Chair of the Department of Biomedical Engineering at Duke University. My research in biomolecular engineering and biointerface science focuses on the development of new molecular tools and technology's that borrow from molecular biology, protein engineering, polymer chemistry and surface science that we then exploit for the development of applications that span the range from bioseparations, plasmonic biosensors, low-cost clinical diagnostics, and drug delivery.
