Dr. Brun is a Fellow of the American Society of Mechanical Engineers (ASME) and won an R&D 100 award in 2007 for his Semi-Active Valve invention. He also won the ASME Industrial Gas Turbine Award in 2016 and 14 individuals ASME Turbo Expo Best Paper/Tutorial awards. Dr. Brun has chaired several large conferences including the ASME Turbo Expo and the Supercritical CO2 Power Cycles Symposium. Dr. Brun is a member of the Global Power Propulsion Society Board of Directors and the past chair of the ASME International Gas Turbine Institute Board of Directors, the ASME Oil & Gas Applications Committee, and ASME sCO2 Power Cycle Committee. He is a member of the API 616 Task Force, the ASME PTC-10 task force, the Asia Turbomachinery Symposiums Committee, and the Supercritical CO2 Symposium Advisory Committee. Dr. Brun is currently Executive Correspondent of Turbomachinery International Magazine and an Associate Editor of several journal transactions. Dr. Wygant is the Senior Manager of Advanced Technology Programs at Elliott Group. In this role he helps define technology needs for future product introduction to the market. Dr. Wygant was previously COO of Hanwha Power Systems Americas, an OEM of integrally geared compressors) where he oversaw business operations in North and South America. He concurrently led new product development of integrally geared products for: LNG, Plant Air, Air Separation, Oil and Gas Applications as well as the design and development of a 5MW super-critical carbon dioxide power system for concentrated power and heat recovery applications. He holds a Ph.D. from University of Virginia and an M.B.A. from Norwich University. Lance Cook, a University of Texas at Austin Petroleum and Geosystems Engineering graduate, has more than 40 years of oil field experience, with his most recent role at Shell as VP of Global Wells Technology. Currently, he is the President and Chief Technology Officer of Sage Geosystems. During his time at Shell, Lance focused on drilling optimization and streamlining drilling operations to achieve efficient and commercially viable outcomes. His expertise lies in driving innovations for practical applications and ensuring lean manufacturing processes in the drilling industry.
