Fengchao Liu got his Ph.D. degree in Materials Science and Engineering in 2010 at the Institute of Metal Research (IMR), Chinese Academy of Sciences. Following his Ph.D., Fengchao had a short career as an academic in China.
He was appointed Assistant Professor by Yanshan University after his graduation and was promoted to be Associate Professor in his 2nd year of appointment. In order to seek a better research environment, Fengchao began to work abroad at Nanyang Technological University (Singapore, 2012) and Osaka University (Japan, 2012-2015), respectively. In 2014, He secured the internationally competitive and highly prestigious Japan Society for the Promotion of Science (JSPS) Postdoctoral Research Fellowship. Fengchao came to the U.S. in 2015 and joined Brigham Young University as a Research Associate (2015-2017). In 2017, he was lucky to become a member of the family of the University of Michigan. He is serving as Assistant Research Scientist at Naval Architecture and Marine Engineering, University of Michigan.
The majority of Fengchao’s research has been on unveiling the inter-relationships between advanced solid-state welding/processing, microstructure, and properties, particularly associated with friction stir welding/processing and dissimilar materials welding. His work on process development as well as microstructure and property evolution (characterized by scanning electron microscope (SEM), electron backscatter diffraction (EBSD), transmission electron microscopy (TEM) and 3D atom probe tomography (3D APT)) in materials modified by advanced solid-state processing has resulted over 40 peer-reviewed scientific articles with more than 1100 citations by 2018.
