We study micro-scale transport phenomena of structurally complex fluids and interfaces, to derive new insights in physico-chemical mechanisms and continuum-scale mechanics of multi-phase soft matter systems, as well as for their applications to solving some of most challenging problems in energy, environment and human health, such as pollutant and disease control, oil recovery, drug delivery and nanomedicines.

We actively tackle problems and explore new research directions by using microscopy, microfluidics, high-speed imaging and image analysis, materials processing and characterization. We also complement our experiments with theoretical modeling and numerical simulations, using ideas from fluid dynamics, polymer physics, colloidal science and biophysics. Our work is thus highly multi-disciplinary, combining expertise from engineering, physics, chemistry, materials science and biology. Our ultimate goal is to bridge fundamental research with meaningful and positive societal impacts.

We enjoy new challenges and collaborations. Feel free to visit us, either in person or on the web.

Team

We are a diverse group of people with backgrounds in engineering, physics, and applied mathematics. Most problems we study lie in the broad space of the dynamics of complex fluids.   Meet our group…

We are always looking for the highly motivated graduate students to join our group. Candidates with strong backgrounds in experimental fluid mechanics, microfluidics, and nanomaterials are strongly encouraged to contact Professor Feng for available opportunities with in our group. We also welcome undergraduate students interested in pursuing research in the group.
