Li-Tang Yan is a full professor with tenure at Tsinghua University in Beijing. He obtained his PhD in polymer physics and chemistry at Tsinghua University in 2007, and then went to Bayreuth University in Germany as a Humboldt Research Fellowship. In 2010, he joined Prof. Anna Balazs' group at University of Pittsburgh in USA as a Postdoctoral Research Fellowship. He returned to Tsinghua University as a faculty in Department of Chemical Engineering from May 2011. In 2020, he obtained the "NSFC Award" for Outstanding Young Scientist. His research interests focus on computational and theoretical aspects of soft matter systems, including macromolecular networks, nanoparticle cellular interactions and nano-engineer materials that are self-assembling and self-regulating.
