Fluid dynamics, micro- and nano-fluidics, particle image velocimetry (PIV), micro-electro-mechanical systems (MEMS), lab-on-a-chip systems, and colloidal self-assembly.
Research within this lab is focused on investigating micro- and nano-scale fluid phenomena. At this scale there are a number of phenomena that dictate hydrodynamic behavior that would normally be negligible in the macro-scale domain including thermal, optical, electrical, and capillary forces. These forces are utilized to design and fabricate novel microfluidic devices capable of a variety of tasks; some examples include (i) hydrodynamic pumping without moving parts, (ii) droplet generation, (iii) particulate trapping and/or sorting, (iv) biological characterization, and (v) self-assembly. Microfluidic investigations are centered around Particle Image Velocimetry (PIV). This laboratory is well-versed in PIV and can obtain a picture of flow fields within micrometer-sized fluid channels. Our goal is to explore the fundamental physics associated with microfluidic hydrodynamics, electrokinetic mechanisms, and colloid-based phenomena and develop related applications involving enhanced engineered materials or point-of-care diagnostics.
