Biography

Greg Nellis received his BS in mechanical engineering from the University of Wisconsin and his MS and PhD in mechanical engineering from MIT. Greg worked in the cryogenic engineering lab at MIT. His graduate work was directed at modeling and building an active magnetic regenerative refrigeration system. After graduation, Greg worked at Creare, Inc., in Hanover, New Hampshire, where he worked primarily under the direction of Walt Swift on projects related to turboBrayton cryocoolers. He was involved in the development of the NICMOS cryocooler that was installed on the Hubble Space Telescope. For the past eight years, Greg has worked at the University of Wisconsin–Madison where he is now an associate professor of mechanical engineering. His research is related to pulse tube and mixed gas cryocoolers as well as near room temperature magnetic refrigeration.
