I am from China and finished my B.E. at Northeastern University in 2007 and Ph.D. at University of Science and Technology of Beijing in 2015. Before joined Northwestern University, I did my postdoctoral research in Lehrstuhl WWI at Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany) and in Rolls-Royces Corporate Lab at Nanyang Technological University (Singapore).

My research includes a new class of intermetallic-strengthening high-temperature cobalt-based alloys and a solid-state additive manufacturing process cold spray. At Northwestern University working jointly in the Dunand and Seidman research groups, my efforts will keep focusing on the cobalt-base alloys in an attempt to design low-cost, oxidation- and creep-resistance alloys using transmission electron microscopy (TEM) and atom probe tomography (APT).
