His postdoctoral work with Dr. David Mooney at Harvard centered on identifying optimal presentation kinetics for pro-angiogenic and pro-vascular maturation growth factors. Controlled release of these factors led to improved vascularization, stromal cell recruitment and vascular remodeling.

As a Fellow of the Wyss Institute at Harvard, Brudno developed the first technology allowing for non-invasive replenishment of drug- and growth factor-releasing hydrogels and surfaces. This widely applicable method allows for repeated, local and controlled release of therapeutic factors in a wide range of diseases, with wide applicability in drug and cell delivery and regenerative medicine. He has also been actively involved in commercializing the refillable depot technology for medical applications.

He applies a multi-scale approach first using top-down multidisciplinary studies to broadly consider how future uncertainties (climate, freight movement, urbanization, etc.) will affect the sustainability, robustness, and resilience of infrastructure systems. His work also applies bottom-up investigations to experiment on and then mathematically describe the engineering and fundamental properties of infrastructure materials, principally asphalt concrete. Collectively these studies seek to identify future challenges and develop fundamentally founded engineering solutions to meet these challenges.

Dr. Katharina Stapelmann

Assistant Professor
Ph.D. (2013), Ruhr University Bochum, Germany

Research Interests: Non-equilibrium atmospheric pressure plasmas and low-pressure plasmas; heating mechanisms; plasma diagnostics; plasma-liquid interaction; interaction of biological material with plasmas; plasma medicine

Stapelmann received her Dipl.-Ing in electrical engineering from the Ruhr University Bochum in Germany. During her studies she conducted a research stay at the Joint Research Center of the European Commission in Ispra, Italy from 2007-08. She received her Ph.D. in electrical engineering from Ruhr University Bochum. Prior to joining the NC State faculty, she was an assistant professor of biomedical applications of plasma technology at Ruhr University Bochum.

Presently, she studies the interactions of technical plasmas with biological systems on a macromolecular level. Her focus is on the characterization and optimization of plasma discharges used for biomedical applications and the understanding and improvement of plasmas used e.g. in medicine. The applications range from wound healing to air purification, sterilization of medical instruments as well as for planetary protection purposes. Furthermore, plasma-liquid interactions and plasma discharges in liquids belong to the repertoire.

Dr. Ge Yang

Assistant Professor
Ph.D. (2007), Northwestern Polytechnical University

Research Interests: Radiation detection materials and devices; effects of radiation on electronic and structural materials; nuclear imaging and measurement; sustainable energies; compound semiconductors

Yang received his B.S., M.S. and Ph.D. in materials science and engineering from Northwestern Polytechnical University. Prior to joining the NC State faculty, he spent ten years at the U.S. Department of Energy’s Brookhaven National Laboratory, working in Advanced Radiation Detector R&D Group. During that time, he was promoted through the ranks (research associate, assistant scientist, associate scientist and scientist) because of his outstanding performance. Yang is a two-time recipient of the prestigious R&D 100 Award, in 2009 and 2014, together with his collaborators for developing various compact sensors to detect and image radiation.

His research interests have revolved around the opportunities at the intersection of nuclear engineering, materials science and engineering and electrical engineering. Special emphasis is placed on developing new materials and devices for improving radiation detection and imaging technologies, which are widely needed in medical imaging, nonproliferation, nuclear security, industrial process monitoring, environmental safety survey and remediation, astronomical observation instrumentation and high energy physics R&D. Yang is also interested in investigating radiation effects in electronic, optical and structural materials and developing radiation-resistant materials. All of these topics are investigated using both theory and experimental techniques.
