Jiyuan is from Beijing, China. He joined the de Pablo group in 2014 and got his Ph.D. degree in 2020. His research was focused on the development of numerical methods to solve hydrodynamic and electrostatic interactions in continuum simulations. Currently, he is working as a Data Scientist in the industry.

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, the group employs 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.
