Eleftherios “Terry” Gdoutos, Ph.D.

Principal Research Scientist

egdoutos@caltech.edu

Dr. Terry Gdoutos studies and develops novel technologies for deployable solar arrays, antennas, and integrated sunlight collection and power beaming arrays, enabling spacecraft to collect solar energy in space and wirelessly beam it to Earth, the Moon or other planets. He is currently leading a multi-disciplinary team of research scientists, engineers, and graduate students on the design, procurement, fabrication, and integration and testing activities for the development of DOLCE, an on-orbit 50 kg technology demonstration of an ultralight deployable structure and deployment mechanism for space-based power stations in Caltech’s Space Solar Power Project.

Previously, Dr. Gdoutos along with a multi-disciplinary team of postdocs and graduate students demonstrated the lightest by a factor of 10 experimentally validated prototype integrating solar power collection and wireless transmission.

Dr. Gdoutos’s expertise includes the analysis, design, construction, and testing of deployable structures with ultralight carbon fiber reinforced plastic (CFRP) components. Dr. Gdoutos also has experience in failure analysis and lifetime assessment of complex thermomechanical systems in rail, mining, and chemical processing. He completed his Ph.D. in Aeronautics at Caltech in 2013 and holds Bachelor of Science degrees from Northwestern University in Mechanical Engineering and Computer Science.
