Ryan Snodgrass is a research scientist at NIST’s Quantum Sensors Group, where he focuses on improving cryogenic refrigeration technologies. His work includes studying pulse tube refrigerators, Gifford-McMahon cryocoolers, and dilution refrigerators that operate at extremely low temperatures. His goal is to make these cooling systems more accessible, compact, and energy efficient, which is crucial for advancing quantum technologies that require stable, ultra-cold environments.
Snodgrass has contributed to projects such as analyzing regenerator cooling power in 4 K pulse tube refrigerators and developing methods for faster cooldown. He also studies miniature dilution refrigerators that use helium-3 and cold adsorption pumps. With a background that includes a Ph.D. and M.S. from Cornell University and a B.S. from Ohio State University, he has been a PREP Associate since 2021 and previously worked as an NRC Postdoctoral Fellow. His research supports the development of more practical and efficient cooling solutions for quantum science and engineering.
