Ben Church
UWM Associate Professor,Materials Science and Engineering
Director of UWM Advanced Analysis Facility
ASM Milwaukee Board Member

Dr. Church joined the UWM faculty after working for Modine Manufacturing in Racine, WI, as a technical advisor in the metallurgical lab. His real-world experience brings energy to his research interests. He is currently working on high-temperature corrosion of materials used in petrochemical processing applications, with a focus on oxidation in steam and resistance to coking and carbon attack. This project is in collaboration with Oak Ridge National Laboratory, Duraloy, and MetalTek International and aims to develop cast alumina-forming austenitic stainless steels for this and other applications.

Joseph Domblesky
Marquette University Faculty Member
Dr. Domblesky has been at Marquette University in Milwaukee, WI since 1996 and is a faculty member in the Mechanical Engineering Department where he teaches manufacturing processes and materials science. His research interests include computational welding, surface engineering (particularly MAO), metal casting, and forming processes. Dr. Domblesky also teaches a workshop in die stress analysis for the cold and hot forming industries in collaboration with Scientific Forming Technologies Corp and was an instructor for the metal forming fundamentals session in the FIA Die School. Prior to becoming a faculty member at Marquette University, he held positions at General Motors and MSW Inc. as a manufacturing engineer and tool room supervisor. Dr. Domblesky has received B.S. and M.S. degrees from the Pennsylvania State University and a Ph.D. in Metal Forming from Ohio State University.

Junjie Niu
UWM Assistant Professor, Materials Science and Engineering
Associate Editor RSC Advances, a publication of the Royal Society of Chemistry
Dr. Junjie Niu is an Assistant Professor in Department of Material Science and Engineering at University of Wisconsin-Milwaukee. He received Ph.D. in Materials Science from Zhejiang University. Before joining in UWM, Dr. Niu worked as a Postdoc Associate at the Massachusetts Institute of Technology (MIT) from 2011 to 2014. He also did interdisciplinary research as a Postdoc Associate at the Drexel University and the University of Pennsylvania (UPenn) from 2009 to 2011. Dr. Niu’s interdisciplinary research includes understanding fundamental science in physics/chemistry/mechanics, and engineering materials in applications of energy storage and water-energy nexus. In particular, lithium-based batteries, advanced lead-acid battery, self-cleaning, water purification and air purification. Dr. Niu has published over 70 papers in peer-reviewed journals including 3 Nature series journals with a total citation 4900+ and h-index of 33 and filed over 5 US patents.
