- CEMS welcomes David Poerschke as a new tenure-track assistant professor in the department. Poerschke earned his B.S. and M.S. in Materials Science and Engineering from Case Western Reserve University and Ph.D. in Materials from the University of California Santa Barbara, where he continued as a postdoctoral scholar. Poerschke's research seeks to understand the evolution of materials in complex chemical, thermal, and mechanical environments. Combining experimental observations with theoretical models, he develops design-performance frameworks to accelerate the development of new materials offering improved performance. His past efforts have lead to the development of improved ceramic coatings for use in jet engines and provided new understanding of the life-limiting oxidation processes in ceramic composites for turbine engine and hypersonic vehicle applications. "Driven by a desire to improve global connectivity while reducing the consumption of fossil fuels, the robust new materials developed by my research enable new transportation technologies while improving the efficiency of the energy technologies that currently serve as the basis for our economy," said Poerschke.
Poerschke's research spans numerous aspects of materials engineering, including synthesis, processing and characterization, which makes it rather unique. Poerschke explained that, "I carried out my undergraduate and M.S. research in a metal processing laboratory, developing improved methods for casting high strength aluminum and magnesium alloys desired for vehicle light weighting, and processes for forming creep-resistant molybdenum alloys. I then shifted to focus on structural ceramic composites and coatings for my PhD and postdoctoral training. This breadth of experience makes me uniquely suited to carry out a research program seeking to integrate multiple classes of materials into high-performance systems. My research takes on a holistic approach, beginning with the synthesis of the constituent materials followed by the processing of composite architectures, testing in complex environments, and finally characterization using tools that span many length scales. In this manner, my students tackle challenging materials science problems while also developing broad skillsets to carry forward into their careers."
Poerschke is poised to have a promising career in CEMS and is energized by the collaborative, interdisciplinary work occurring here. "By bringing together scientists with interests spanning across chemical engineering and materials science under one roof, CEMS at UMN provides a unique environment for cutting-edge science at the convergence of these disciplines. In combination with the caliber of the students and access to world-class electron microscopy, X-ray diffraction, and surface analysis instruments in the CharFac, CEMS is well-positioned to enable future breakthroughs. I’m proud to be part of the CEMS faculty who collectively demonstrate serious commitments to research and teaching, while also striving to foster an inclusive and collegial atmosphere of learning and discovery," said Poerschke.
Poerschke is an active member of the American Ceramics Society, and serves as a contributing editor for NIST-ACerS Phase Equilibria Diagrams Database.
