Dr. Cullinan's research focuses on the development of novel nanomanufacturing systems and on finding ways to exploit nanoscale physical phenomena in order to improve existing macroscale devices and to create novel micro- and nanoscale devices for energy and sensing applications. His research interests include the design and development of nanomanufacturing processes and equipment, the application of nanoscale science in engineering, the engineering of thin films, nanotubes and nanowires, the manufacturing and assembly of nanostructured materials, and the design of micro/nanoscale machine elements for mechanical sensors and energy systems.
