Since 2013, his research teams have been awarded approximately $2.5 million in grants among several studies designed to investigate fugitive methane emissions from natural gas throughout the entire supply chain. Most recently, along with Dr. Omar Abdul Aziz, Dr. Johnson was awarded a three-year grant of more than $320,000 from the National Science Foundation to study methane emissions from gas well sites, with the mission of using new technology to better quantify lost emissions and reducing the current uncertainties between studies. Prior to his current position, Dr. Johnson was an engineer for CONSOL Energy, Research and Development. He holds a B.S., M.S., and Ph.D. in Mechanical Engineering from West Virginia University.
