after completing his post-doctoral work, garner moved to california, to take up the position of area manager of parc san francisco research division in 2009. this allowed him to undertake further work in photovoltaics, sustainable engineering and other technologies designed to innovate parc products to be "environmentally friendly". parc currently conducts research into "clean technology", user interface design, sensemaking, ubiquitous computing and context-aware systems, large-area electronics, and model-based control and optimization in embedded, intelligent systems. garner is currently managing the energy systems group in the hardware systems laboratory, and has a focus on cleantech, of which parc is a major sponsor. garner's current work is focussed on advanced cooling technologies for next-generation air conditioning and refrigeration; atmospheric co2 capture for renewable, infrastructure-compatible liquid fuels; and enhanced geothermal systems. he has presented many papers at conferences and will be discussing parc's sensor: (smart embedded network of sensors with optical readout) at the arpa-e energy innovation summit.
