Biography
Dr Liyan Wu is an assistant research professor at Drexel University and works in the Mesoscale Materials Laboratory led by Prof. Jonathan E. Spanier in the Department of Mechanical Engineering and Mechanics. He received his BEng degree from Northwestern Polytechnical University in China in 2011 and PhD from University of Pennsylvania in 2019. Dr Wu’s research focuses on functional oxides, especially their ferroelectric, piezoelectric and dielectric properties. His approach exploits the symmetry-property relationships by achieving high control of the materials structures at different length scales, combined with a detailed understanding of the physics mechanisms.Degrees / Education
