(340ah) Bacteria As Active Colloids at Fluid Interfaces

I am a Ph.D. candidate in Department of Chemical and Biomolecular Engineering at the University of Pennsylvania with expertise in colloidal science, biophysics, statistical analysis, and interfacial sciences. My current research interests focus on understanding the non-equilibrium phenomena arising in active suspension of bacteria and in colloidal crystals under external fields. Specifically, I study the locomotion of bacteria on fluid interfaces where hydrodynamic interactions and interfacial mechanics constrain their behaviors. I visualize the microscale flow around the bacterium and develop theoretical understanding of pairwise interactions between active-passive and active-active colloids using statistical mechanics and fluid dynamics. In addition, I study the role of hydrodynamic interactions in a 2D colloidal crystal stabilized by electrostatic repulsions from analyzing the structural order and long-range correlated motion of the colloids with the presence of external force and torque.

Through years of lab work during my PhD, I have developed solid skills with mathematical modeling and numerical simulation in colloidal physics and high-throughput data analysis and visualization. Furthermore, I am also familiar with experimental tools including interfacial characterization techniques (Pendant Drop, Goniometer, Microrheology), optical imaging techniques (Optical Microscopy, Holography, Confocal Microscopy) and general cell culture skills. I am eager to apply my academic trainings in industry and I am actively applying for R&D roles in chemical engineering and related industries.
