PhD, Materials Science and Engineering, Carnegie Mellon University

Prof. Paul Ohodnicki has a wide range of research interests spanning magnetic, optical, and electronic functional materials and their device level applications.  He has a particular interest in the science and engineering of nanocomposite based materials with multiple phases intermixed at the nm-scale, for which the tailoring of chemistry, microstructure, and even atomic level defects can enable new properties that are not attainable in conventional materials.  Such materials have been applied to a wide range of device level applications including both optical fiber and passive wireless sensors, as well as magnetic components for power applications including inductors, transformers, and rotating electrical machinery. 

Prof. Ohodnicki embraces interdisciplinary research with a particular interest in challenging scientific topics that require expertise spanning the traditional disciplines of materials science, physics, and electrical engineering.  In addition to his research interests, he also serves as the associate coordinator for the engineering science program which promotes an interdisciplinary science and engineering education uniquely tailored to solve such challenging problems.
