About the Lab
The Hwu Lab focuses on developing innovative tools at the interface of nanotechnology, microscopy, and biomedical engineering. Much of the group’s research centers on advancing atomic force microscopy (AFM) and piezoelectric positioning systems, with an emphasis on making them faster, more affordable, and more accessible through creative hardware design and optical detection methods. In parallel, the lab develops microfluidic and Lab-on-a-Disc (LoD) platforms, as well as microscale 3D-printed devices such as check valves and oral drug delivery systems, aimed at enabling portable diagnostics and improving healthcare technologies. The research bridges fundamental engineering with biomedical applications, including skin barrier assessment, infectious disease models, and targeted drug delivery. Students joining the lab can expect to work on projects combining precision instrumentation, optics, microfabrication, and applied nanoscience. The lab is a strong fit for students interested in experimental innovation, with backgrounds in physics, mechanical/electrical engineering, materials science, or bioengineering. Creativity, hands-on problem-solving, and an interest in translating technologies to healthcare and diagnostics are especially valued.
