Jie Feng is a PhD candidate in the Department of Mechanical and Aerospace Engineering at Princeton University. He works with Prof. Howard A. Stone in the Complex Fluids Group. Prior to coming to Princeton University, he obtained a B.S. and M.S. in the Department of Thermal Engineering at Tsinghua University, China. He is interested in studying the physical mechanisms of particle-interface interactions as well as their environmental consequence and potential applications in biology and materials science. Interfaces between two distinct phases are ubiquitous in engineering applications and natural phenomena. The properties of such complex interfaces are crucial to the response of many systems. Particles, such as droplets and bubbles, behave differently near complex interfaces as opposed to when they are in a bulk system. These particle-interface interactions influence a wide range of phenomena involving mass and energy transport. Therefore, understanding the physics of how particles interact with interfaces remains a canonical problem with strong intellectual interest and industrial impact. His current research interests include bubble dynamics at the interface, functional emulsion fabrication with bubble bursting and droplet migration in microfluidics. Apart from academics, he enjoys playing soccer and basketball, and his other favorite hobbies include playing ukulele and SINGING!
