The following are highlights from research that touch on my work with fluids and fluid dynamics. When available, links are included to provide more technical information about the project, such as in reports and presentations. Please don't hesitate to contact me via my Linkedin if you would like to discuss my work in more detail.

Designed a modular, fully reconfigurable microfluidic network using micromachined, store-bought LEGO bricks as modules.

We built a device to apply tuned two-dimensional acoustic fields to assemble millions of microparticles into hundreds of crystallites in a single step within a resonating chamber.

Developed a vane with a fractal cross section to provide more even shear stress on measured fluids while retaining good traction to prevent fluid slip. The design is 3D printable and available free online for download.
