Hongjun Zeng has extensive expertise in the field of carbon nanomaterials, composite materials and related topics. As Director of R&D at Advanced Diamond Technologies, Inc. (ADT), he developed commercial processes to manufacture nanocrystalline diamond — another carbon nanomaterial with novel properties — into an enabling material for industrial, biomedical and clean tech applications. His interests include broader advanced manufacturing, micro & nanofabrication methods, semiconductor process, and micro-devices to reach limit-breaking goals. His experience combines the unique properties of materials and novel manufacturing approaches to realize devices with performances that cannot be achieved with conventional techniques. His career in CAS, UIC, and ADT led to more than 50 peer-reviewed publications and 13 patents/disclosures. He holds a Ph.D. in Optical Engineering.
