NASA Langley Research Center Director Lesa B. Roe, Deputy Director Stephen G. Jurczyk and Director of Systems Analysis and Concepts Dr. Ajay Kumar have been awarded the Presidential Rank of Meritorious Executive. Dr. Bruce Wielicki has been awarded the Presidential Rank of Meritorious Senior Professional.
The honor of Presidential Rank is bestowed on a small number of career senior executive service members who have exhibited exceptional performance that is recognized throughout the government on a national or international level. Not more that five percent of government career executives are awarded the meritorious rank.
As a senior management official, Roe oversees the 2,000 civil service and 1,600 contract employees who conduct aerospace research at one of the nation's premier federal laboratories and NASA's original field center. Since 1917, Langley has worked to advance aerospace vehicle research and technology development as well as scientific understanding of the chemistry and radiation characteristics of all planetary atmospheres.
Dr. Kumar leads over 100 researchers and engineers at Langley who conduct studies to provide mission architectures, advanced systems concepts, life cycle cost and risk analyses, systems integration and other critical information to enable informed technical programmatic and budgetary decisions on potential missions and aerospace initiatives. Prior to his current assignment, he served as director of the Aerodynamics, Aerothermodynamics, and Acoustics Directorate. Dr. Kumar began his NASA career in January 1981 as an aerospace engineer in hypersonic propulsion.
Dr. Wielicki is NASA Langley's senior scientist for radiation sciences. He is the principal investigator on the NASA Clouds and the Earth's Radiant Energy System (CERES) and co-investigator on the NASA CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite missions. He is recognized as an expert in radiation and clouds as they relate to global climate change. Dr. Wielicki began his NASA career in 1980 as a scientist studying ways to remotely sense Earth's climate from space.
