Dr. Jie Feng

Jie Feng is Assistant Professor in the Department of Mechanical Science & Engineering at the University of Illinois at Urbana-Champaign. He obtained his Ph.D. in Mechanical & Aerospace Engineering from Princeton University under the guidance of Prof. Howard A. Stone, and did his postdoctoral research with Prof. Robert Prud’homme in Chemical & Biological Engineering at Princeton University before joining the University of Illinois in 2019. He received the Gordon Wu Prize for Excellence and Wallace Memorial Honorific Fellowship for exceptional promise in research from Princeton University in 2016.

I am interested in the fluid mechanics in interfacial phenomena related to energy, environment, and biology. Now I am working on the dynamics of oil-coated bubble impacting a complex interface for understanding oily aerosol transportation from marine, and foam dynamics for oil-enhanced recovery.
