Biography

Joseph Toombs is a PhD candidate in the Design for Emerging and Nanoscale Manufacturing lab at the University of California, Berkeley advised by Professor Hayden Taylor.

His research spans optical, mechanical, and material science challenges related to advancing microscale volumetric additive manufacturing (VAM). In addition, he develops computational methods and optimization techniques to support the development of novel tomographic VAM configurations as well as optical metrology techniques for VAM. A key research topic he is investigating currently is how microscale computed axial lithography can be scaled to maximize the overall build volume while maintaining a microscale minimum feature size.
