Professor, Materials Science and Engineering
BioLisa Porter received Ph.D. and B.S. degrees in Materials Science & Engineering from N.C. State University and Cornell University, respectively. She serves as a research and academic advisor to both graduate and undergraduate students and is actively involved in several outreach activities and societies. She serves on the Board of Directors of the American Vacuum Society (AVS), an international society pertaining to the Science & Technology of Materials, Interfaces, and Processing. She is also the Program Vice-Chair for the AVS 62ndInternational Symposium. Her awards include the Philbrook Prize in Engineering from CMU (2012), “Women Driving the Material World” Award from the Women & Girls Foundation (2006), a National Science Foundation Career Award (1999-2004) and a National Swedish Foundation Visiting Professorship (2000-2002).

ResearchProfessor Porter's research activities are focused on the analysis of chemistry, microstructure, and electrical properties of electronically-functional interfaces. We are interested in a range of materials including wide band-gap semiconductors; transparent conductors based on nanostructured composite materials, and two-dimensional semiconductors. We are also interested in a range of applications and devices, including solar cells, chemical sensors, and devices for high-power, high-temperature and other extreme conditions. Examples of current research projects include organic photovoltaics (OPV) with nanostructured transparent conductors; electrical contacts to 2D semiconductors; and materials characterization and device processing for wide bandgap semiconductor devices based on Ga2O3.
