Management Appointments Announced at NASA Dryden

EDWARDS, Calif. - Kevin L. Petersen, Director of NASA's Dryden Flight Research Center at Edwards Air Force Base, recently announced appointments to several management positions at the NASA field center.

Dennis O. Hines has been appointed Associate Director of Programs, responsible for the advocacy, formulation and implementation of the center's flight projects, policy and business management of the center's programs.

John G. Zellmer has been appointed Chief of Protective Services, responsible for management of the center's security, emergency preparedness and law enforcement programs.

Albion H. Bowers has been named Director of the center's Aeronautics Mission Directorate, responsible for management and oversight of a variety of aeronautics-related research projects at NASA Dryden. He supervises managers of those projects and plans for current and future NASA work in the field of aeronautics.

Brent R. Cobleigh recently accepted the post of Director of the Exploration Mission Directorate at NASA Dryden. In this position, Cobleigh is responsible for managing Dryden's support of NASA's Constellation program. Constellation projects include integration and flight test of the Orion Launch Abort System for crew escape in case of an abort upon launch and potential development of a vehicle to train astronauts for future moon landings.

Hines comes to NASA Dryden from the Missile Defense Agency of the Department of Defense, where he headed organizations responsible for directing integration of the engineering, programmatic and operational aspects of the Ballistic Missile Defense System and for all systems engineering and technical analysis required to define ballistic missile targets and countermeasures needed for missile defense system flight testing. Prior to those assignments, he served the agency as deputy executive officer for the Ballistic Missile Defense System.

Hines was previously employed for 22 years in a variety of engineering and management roles at the Air Force Flight Test Center at Edwards Air Force Base for 22 years, including four years of active duty in the Air Force. He holds master's degrees in systems management and mechanical engineering.

Zellmer has extensive experience in the intelligence and security fields, both within the military and civilian government agency sectors. A veteran of 24 years in the Air Force, much of it in the military intelligence field, Zellmer retired with the rank of lieutenant colonel in 2001. He then served for three years as lead security specialist with the Global Hawk Flight Test Program at Edwards Air Force Base. From 2004 through 2007, he was Chief of Program Protection for Acquisition Security at Edwards, responsible for a range of information and operational security issues.

Zellmer earned a bachelor's degree in political science from the University of Wisconsin at LaCrosse and a master's degree in organizational and business security management from Webster University, St. Louis.

Bowers came to NASA Dryden in 1982 after earning a Bachelor of Science in aeronautical engineering and a Master of Engineering from California Polytechnic State University, San Luis Obispo. As a research engineer at NASA Dryden specializing in aerodynamics and systems engineering, Bowers has been involved in a number of projects involving aerodynamics, boundary layer airflow, fundamental fluid dynamics, flight mechanics, advanced controls, and structures research.

Prior to his present position, Bowers served as chief of the aerodynamics branch of Dryden's Research Engineering Directorate from 2002 to 2004 and as acting Deputy Director of the Research and Engineering Directorate from 2004 to 2008.

Cobleigh came to NASA Dryden in 1989, working in a variety of technical disciplines such as flight dynamics, simulation modeling and advanced airdata systems on many flight projects. From 2000 to 2002, Cobleigh was chief engineer on the Autonomous Formation Flight project, and then served a one-year detail as a program analyst for the Vehicle Systems Program at NASA Headquarters as part of the NASA Leadership Development Program.

From 2004 until his present appointment, Cobleigh was project manager for the procurement, development and operation of NASA's Ikhana / Predator B unmanned aircraft and ground control systems. He has authored or co-authored over 21 technical papers and earned four best technical paper awards, as well as receiving numerous NASA awards for his work.

Cobleigh holds a bachelor's degree in aerospace engineering from California State Polytechnic University, Pomona and a master's degree in aeronautical engineering from the George Washington University, Washington, D.C.
