My research is in complex transport phenomena, with an emphasis on using advanced experimental techniques to extract quantitative measurements from complicated phenomena. My group strives to answer fundamental scientific questions about a variety of systems where the transport behavior is paramount. Recent topics include: electrocoalescence of charged droplets, electrically-induced aggregation of colloids near electrodes, extraction dynamics in coffee, and turbulent dispersion of airborne pathogens. My lab has two Phantom high-speed cameras (a grayscale v7.1 and a color v7.3), both of which can capture at more than 100,000 frames per second. We also have several microscopes and various optical and laser systems.
I am also passionate about coffee – I serve as Director of the UC Davis Coffee Center, and my undergraduate course, The Design of Coffee: An Introduction to Chemical Engineering, regularly enrolls more than 2,000 students per year.
