Cockrell Family Regents Chair in Engineering, The University of Texas at Austin
Peppas was educated in chemical engineering at the National Technical University of Athens (D. Eng., 1971) and at the Massachusetts Institute of Technology (Sc.D., 1973) under the direction of bioengineering pioneer Edward W. Merrill. Subsequently, he was a postdoctoral fellow in the Arteriosclerosis Center of the Massachusetts Institute of Technology under world biomedical leaders Clark K. Colton, Kenneth A. Smith and Robert S. Lees.
He is the Cockrell Family Regents Chair #6 in Engineering at the University of Texas at Austin. He has been at the University of Texas at Austin since December 2002 and is serving as the Director of the Institute of Biomaterials, Drug Delivery, and Regenerative Medicine, and its Laboratory of Biomaterials, Drug Delivery and Bionanotechnology  with appointments in the Department of Chemical Engineering, the Department of Biomedical Engineering and the College of Pharmacy at the University of Texas at Austin. Before 2002, he was the Showalter Distinguished Professor of Biomedical Engineering and Professor of Chemical Engineering at Purdue University.
Peppas is a leading researcher, inventor and pacesetter in the field of drug delivery and controlled release, a field that he developed into a mature area of scholarly research. He is also a leader in biomaterials, bionanotechnology, nano materials and bionanotechnology, and has contributed seminal work in the fields of feedback controlled biomedical devices and molecular recognition. The multidisciplinary approach of his research in bionanotechnology and biomolecular engineering blends modern molecular and cellular biology with engineering to generate the next-generation of medical systems and devices, including bioMEMS with enhanced applicability, reliability, functionality, and longevity. His contributions have been translated into more than twenty medical products.
