Biography
Dr. Liang Dai joined the Department of Physics as an Assistant Professor in Oct 2018 and was promoted to Associate Professor in July 2023. Previously, he worked as a research scientist at Singapore-MIT Alliance for Research and Technology (SMART) and as a postdoc at Indiana University. Dr. Dai obtained his BSc degree from the University of Science and Technology of China in 2004, and his Ph.D. in physics from the National University of Singapore in 2009.
Research Interests/Areas
Dr. Dai applies multi-scale modeling, from atomistic to coarse-grained, and statistical mechanics to perform research in soft matter physics and biophysics, with tight collaboration with experimental groups. In addition to addressing fundamental physics problems in soft matter systems, Dr. Dai is interested in practical applications such as design of antimicrobial peptides for antibiotic drugs, and DNA sequencing technologies based on nanopores or nanochannels.
