Gary Matlock, Deputy Assistant Administrator for Science

Gary Matlock

Deputy Assistant Administrator for Science

Dr. Gary Matlock is serving as the Deputy Assistant Administrator for Science for Oceanic and Atmospheric Research.


He is responsible for guiding and evaluation of NOAA’s research and development portfolio. Prior to arriving at OAR, he spent 18 years working in three other NOAA Line Offices directing ecological and fisheries related research and overseeing the agency’s national and international fisheries management programs.

Dr. Matlock began his federal career with NOAA's National Marine Fisheries Service in 1992 as the Director of Field Operations in the Southwest Region where he became the Acting Regional Director after 3 months. During his year’s tenure in these positions, he was involved in the management of domestic and international fisheries along the west coast of the United States and throughout the southern Pacific Ocean. In 1994 he became the Program Management Officer for the National Marine Fisheries Service (NMFS) in Silver Spring, Maryland where he oversaw the day-to-day operations of the agency, expanding his fisheries management experience domestically and internationally to the north Pacific Ocean and the Atlantic Ocean. In 2000, he became the Director of the National Centers for Coastal Ocean Science in the National Ocean Service (NOS) where he was responsible for directing and managing an ecosystem science agenda that provides science to support the Ocean’s Service place-based management mission. He also served as the Acting Director of NOAA’s Program Analysis and Evaluation (PAE) office and as Acting Assistant Administrator of the NOAA’s Policy, Planning, and Integration (PPI) Office.

Prior to joining NMFS, Dr. Matlock spent his fisheries career with the Texas Parks and Wildlife Department (TPWD). His dissertation provided a basis for the management of the red drum fishery in Texas. He began as a fisheries biologist responsible for developing a monitoring program for adult finfish in Texas bays and left TPWD after having been the Director of Fisheries of TPWD. During his tenure with TPWD he earned his Ph.D. in Wildlife and Fisheries Sciences at Texas A&M University and conducted and published the results of research in the scientific literature on many fisheries management and aquaculture topics including those involved with biology, sociology, and economics.

Throughout his career, he has successfully led an effort to base fisheries management decisions on scientific information instead of political whim or personal opinions. This goal has taken him to all levels of the judicial system as an expert witness on behalf of science and fisheries management decisions, including the U.S. Supreme Court where a NMFS decision concerning native American tribal treaty rights and salmon on the west coast was upheld. He has and continues to publish in the national and international scientific literature on the biological, ecological, social, and economic aspects of fisheries science and management.

He received a U.S. Department of Commerce Gold Medal in 1996, and the Vice President’s Hammer award in 1998 for his efforts to reform the fisheries management regulatory process. He received another Gold Medal in 2000 for having led the development of an e-commerce based program for requiring and issuing a financially self-sustaining Atlantic tunas fishing permit (the first marine recreational fishing permit in the U.S.)

What We Do

NOAA and the nation depend on the cutting-edge science provided by its research programs. Recently, NOAA Research built much of the foundation for the modernization of the National Weather Service. The research programs provide the science necessary to help NOAA achieve its goals to:

  • serve society’s needs for weather and water information;
  • lead the effort to understand and monitor climate variability and change to enhance society’s ability to plan and respond;
  • work to protect, restore and manage the use of coastal and ocean resources through ecosystem-based management; and
  • support the Nation’s commerce with information for safe, efficient and environmentally sound transportation.

Working under the broad themes of Climate, Weather and Air Quality, and Ocean and Coastal Resources, NOAA scientists study the ocean’s depths and the highest reaches of space to better understand our environment. NOAA’s long-term commitment to the highest quality research includes engaging in-house and extramural talent to:

  • continue to conduct experiments to understand natural processes (physical, geochemical, ecological);
  • build predictive models for use in weather, air quality, climate, solar, ocean, emergency management, and coastal assessments and predictions;
  • develop and deploy new observing technologies to provide data to support predictive models and to document natural variability;
  • develop new analytical and forecast tools to improve weather services;
  • use new information technology to share information with other federal and academic scientists; and
  • prepare scientific assessments and information products to enhance public education and guide governmental action.

Research plans and products are developed in partnership with academia and other federal agencies, and are peer-reviewed and widely distributed. A high premium is placed on external collaboration both domestically and internationally. In addition, personnel management practices of hiring, promotion, and awards are based on demonstrable capability through internal and external peer assessment. Peer review, collaboration, and partnerships ensure that NOAA’s research is of the highest quality and remains focused on critical issues.

How the Nation and the World Benefit

Most of the environmental questions our nation and the world face are not easily answered. A strong NOAA is necessary to tackle the complex issues that only advanced scientific knowledge is able to adequately address. NOAA Research answers the call and:

  • provides comprehensive knowledge to guide national environmental policy decisions, including better predictions of the climate response to emissions changes, choices for protection of the ozone layer, and alternatives for developing coastal communities;
  • improves environmental services to the nation, including reliable predictions and assessments; and
  • promotes economic growth through science for decision-making, new technology, and partnerships with academia and industry;

NOAA is a world leader in environmental science today and is well positioned and organized to provide the sound scientific research policy-makers will always need.

OAR's Strategy

OAR Strategy 2020-2026_Page_01

OAR has updated its Strategy in order to be successful in the future, to effectively deliver NOAA’s future and be competitive in the environmental R&D market. This new strategy will guide our future research and resource decisions to foster an innovative and integrated research enterprise dedicated to advancing our understanding of the oceans and atmosphere.

In addition, the NOAA Science Council is working to develop the next NOAA 5-Year Research and Development Plan following the FY13-17 iteration. As with the OAR Strategy, this 5-year plan will be closely tied to NOAA's Strategic Plan, describing how we will integrate our research and development activities across each of NOAA's Line Offices in support of NOAA's service and stewardship mission. You can provide input and follow the development of this plan on the NOAA Science Council website.
