Education and Professional Experience

  • Ph.D., Department of Aeronautics and Astronautics, Massachusetts Institute of Technology, 2004
  • M.S., Department of Aeronautics and Astronautics, Massachusetts Institute of Technology, 1999
  • B.S., Department of Aeronautics and Astronautics, Massachusetts Institute of Technology, 1997
Dr. Spadaccini is the Director, Center for Engineered Materials, Manufacturing and Optimization at LLNL. He has been a member of the technical staff in the Materials Engineering Division for the past ten years. He is currently the Principal Investigator for several advanced materials and additive manufacturing projects. He is also the founder and director of a new additive manufacturing, process development, and architected materials center. The work in these laboratories focuses on developing next-generation additive processes that are capable of micro- and nano-scale features and have the ability to create components with mixtures of materials ranging from polymers to metals and ceramics. Development of these processes also involves the synthesis and materials science of feedstocks such as photopolymers and nanoparticles. These capabilities are utilized to fabricate microarchitected materials with unique designer properties, such as negative thermal expansion. Dr. Spadaccini is also a part-time lecturer at the San Jose State University in the Biomedical, Chemical and Materials Engineering Department, where he teaches graduate courses in advanced transport phenomena.
