Microdevices and Nanomaterials
Welcome to the web site for Asst. Prof. Joseph J. Brown’s Nanosystems Lab in the Department of Mechanical Engineering at the University of Hawai‘i at Mānoa.
We work on microscale and nanoscale devices and structures. This work spans the fields of materials development and characterization, micro/nano device development, and applied mechanics. We draw from chemistry, physics, and mathematics to think about the world and explore new ideas for fundamental insights or manufacturable innovations.
Current areas of interest include ALD-enabled devices, renewable materials, interface physics/contact electrification, and geometric nonlinearity in mechanics.
Our work is primarily experimental, but can also involve theoretical and computational analysis.
