Joan M. Redwing

Joan M. Redwing is a Professor of Materials Science and Engineering and Electrical Engineering at Pennsylvania State University's College of Earth and Mineral Sciences. She serves as Director of the NSF 2D Crystal Consortium (2DCC) Materials Innovation Platform and holds an adjunct appointment in the Department of Electrical Engineering. Dr. Redwing is also a member of the Materials Research Institute and serves as vice president of the American Association for Crystal Growth.

Dr. Redwing received her B.S. in Chemical Engineering from the University of Pittsburgh and her Ph.D. in Chemical Engineering from the University of Wisconsin-Madison. After completing her Ph.D., she worked as a research engineer at Advanced Technology Materials, Inc. before joining the Penn State faculty in 2000.

Dr. Redwing's research focuses on electronic and optoelectronic materials synthesis and characterization, with special emphasis on metalorganic chemical vapor deposition (MOCVD) processing of semiconductor thin films and nanomaterials. Her current work centers on the synthesis of 2D materials, particularly transition metal dichalcogenides (TMDs), for applications in nanoelectronics, biomimetic devices, and photonics. She also continues research on wide bandgap group III-nitride materials for solid-state lighting and power electronics. Her research group utilizes custom-designed MOCVD tools with in situ monitoring capabilities for fundamental studies of van der Waals epitaxy and wafer-scale growth technologies.

• Fellow of American Physical Society (APS)
• Fellow of Materials Research Society (MRS)
• Fellow of American Association for the Advancement of Science (AAAS)
• Fulbright Scholar to Sweden (2016)

Dr. Redwing has mentored numerous graduate students, including recent PhD graduates Dr. Tom Mc Knight and Dr. Pat Rondomanski. Her research is supported by the National Science Foundation through the 2D Crystal Consortium, a Materials Innovation Platform national user facility. She serves as associate editor for the Journal of Crystal Growth and as North American regional editor for the journal 2D materials. Dr. Redwing is a co-author on over 300 refereed journal publications and holds 8 U.S. patents related to semiconductor materials processing.

Dr. Redwing leads research in the NSF-supported 2D Crystal Consortium facility at Penn State, which features state-of-the-art MOCVD systems capable of growth at temperatures up to 1500°C. Her team works on fundamental mechanisms of van der Waals epitaxy of layered chalcogenides and the development of wafer-scale epitaxial growth technologies for TMD monolayers and heterostructures. The facility incorporates in situ monitoring during growth and ambient controlled characterization of samples post-growth.
