Center for Engineered Materials and Manufacturing (CEMM)

Eric Duoss

Eric Duoss is the Director of the Center for Engineered Materials and Manufacturing, where he directs research activities and maps strategic directions in the areas of advanced materials and manufacturing. Duoss leads teams that invent novel materials and manufacturing technologies, with focus on creating designer architectures for chemical, mechanical, thermal, and functional properties for applications in the fields of defense, climate, transportation, energy, aerospace, human health, and others.

Duoss is a recipient of the Presidential Early Career Award in Science and Engineering and his team was honored with the Department of Energy Secretary’s Achievement Award in 2019. He has co-authored over 90 peer-reviewed technical publications that have collectively received over 12,000 total citations and has been awarded more than 50 U.S. patents. He earned his Ph.D. in materials science and engineering from the University of Illinois at Urbana-Champaign and holds dual B.S. degrees in chemistry and mathematics from St. Norbert College (2003).

Caitlyn Krikorian

Caitlyn Krikorian (Cook) is the group leader for the Functional Architected Materials Engineering (FAME) group and the deputy director for CEMM. As deputy director, she fosters collaboration and supports interwoven goals in materials development and advanced manufacturing and helps bridge the gap between multiple disciplinary backgrounds to solve science and technology challenges for our national security. She has a B.S. in materials engineering and an M.S. in polymer science and coatings from California Polytechnic State University – San Luis Obispo. She joined LLNL as a student in 2016 and was hired as a member of the technical staff in 2017.

Her research interests include the understanding of structure-property relationships and curing kinetics in polymers and the micro- and nanofabrication of hierarchically engineered materials for multifunctional integration. Her work is focused on developing and characterizing unique, functional photopolymers, especially responsive materials for additive manufacturing and engineered materials for flexible electronic technologies. She also has experience with solvent encapsulation advanced manufacturing processes, making new shell materials and forming capsules at scale for downstream industrial applications.

Chris Spadaccini

Christopher Spadaccini currently leads the Materials Engineering Division in the LLNL Engineering Directorate. He has been working in advanced additive manufacturing process development and architected materials for over 14 years and has over 70 peer-reviewed publications, more than 100 invited presentations, and over 50 patents awarded or pending.

Spadaccini has founded several new fabrication laboratories at LLNL for process development focused on micro and nano-scale features and mixed material printing, as well as scale-up for higher throughput. He was the founding director of CEMM and co-led efforts to establish the Advanced Manufacturing Laboratory, a new facility in the Livermore Valley Open Campus. He has been a member of the LLNL technical staff for 18 years.

Elaine Lee

Elaine Lee is the Group Leader of the Responsive and Active Materials and Manufacturing Group at CEMM. She has expertise in additive manufacturing processes, flexible optoelectronic technologies, electrophoretic deposition, microencapsulation, colloidal processing, micro- and nanofabrication, and materials characterization with focus on soft materials, polymers, colloids, photonic crystals, and liquid crystals. Current projects include developing the controlled release of microencapsulants, engineered materials for flexible optoelectronic technologies, and additively manufacturing shape changing materials.

Lee earned her B.S. in materials science and engineering from MIT and her M.S. and Ph.D. in materials science and engineering from the University of Pennsylvania. She joined LLNL in 2015 as a postdoc and became a member of the technical staff in 2017. She has extensive leadership experience and a passion for volunteering and participating in professional networking groups and societies, particularly for K-12 and underrepresented groups in STEM.

Andrew Pascall

Andrew Pascall is the group leader for the Colloidal Advanced Manufacturing Processes group in the Center for Engineered Materials and Manufacturing. He received his B.S in chemical engineering from UC Berkeley and his Ph.D. in chemical engineering from UC Santa Barbara before joining LLNL as a postdoc. Pascall is an expert in electrophoretic deposition for additive manufacturing. He is also known for his work in electrokinetics, microfluidics, and printing 3D micro-mechanical logic gates.
