Gary's areas of specialization coming to NIST were fluid-dynamical stability theory, and numerical modeling of fluid flow with combined heat- and mass-transfer. As his collaborators left NIST, and due to time commitments to outside interests, instead of pursuing these areas on his own, Gary found application for his skills as a programmer, and his willingness to take on projects requiring entirely new areas of expertise, transitioning to primarily a support role. He builds packages for software installation, does web programming (design and implementation), supports the ongoing series of Symposia on Thermophysical Properties hosted by NIST (every 3 years), and assists the TRC Group with software for generation and maintenance of the online ThermoML archive of thermophysical property data. He is also the Division IT Security Officer.
Gary is also an ordained Zen Monk/Priest, has been the main person running the Boulder Zen Center for 20 years, and is the practice leader. He owns a small inn (bed and breakfast) in Boulder Colorado that supports the zen center. He continues to participate in 7-day retreats at the zen monastery in Crestone, Colorado.
