Dynamic behaviors of many biological, colloidal and other soft matter systems are often driven by both electrostatic and hydrodynamic interactions(HIs). Challenges: 1) Polarization effects can significantly affect the electrostatic interactions in those systems where dielectric contrast between solute and solvent exists. However, for the complexities associated with the many-body nature of polarization, these effects are frequently ignored in computational modeling; 2) HIs are long-ranged thus making it even harder to solve the governing equations when studying the dynamic behavior of finite-size particles in confined flow. To address these challenges, we employ a set of numerical methods to resolve both polarization effects and HIs, and develop powerful integrated simulation package that enables a better understanding of dynamic behaviors of particles, for example cells, DNAs, in flow.
Jiyuan is from Beijing, China. He was enrolled in Beijing University of Aeronautics and Astronautics when he was 16, and got his Bachelor degree of Aeronautical Engineering in June, 2014. In his third year, he was greatly inspired by a lecture given by a soft matter scientist, Prof. Masao Doi from Japan, and then decided to jump from his beloved helicopter lab to the soft matter lab led by Prof. Doi in The International Research Institute for Multidisciplinary Science (IRI) of BUAA. Currently he is pursing his Ph.D in the Institute for Molecular Engineering, University of Chicago, advised by Professor de Pablo. He enjoys basketball, soccer, kayaking, hiking and traveling.
