Biography
Hongyu Liu is a Chair Professor at the Department of Mathematics, City University of Hong Kong. Before taking up the current position, he held faculty positions at Hong Kong Baptist University (2014-2020), University of North Carolina, Charlotte, USA (2011-2014), University of Reading, UK (2010/11), and University of Washington, Seattle, USA (2007-2010). He obtained his PhD in Mathematics from The Chinese University of Hong Kong (2007). His research focuses on the analysis, computation and applications of inverse problems and imaging, wave propagation, partial differential equations, mathematical materials science, scattering theory, spectral theory, the theory of large-population games and mathematical biology. He has also been working on the interplay among scattering methods, biomimetic learning and artificial intelligence.
