Vanessa Griffin has over 40 years’ experience in the Federal Government helping foster the research, development, and operations of the Nation’s critical environmental satellites and IT. As the Director of NOAA/NESDIS’s Office of Systems Architecture and Advanced Planning (OSAAP), Ms. Griffin directs the architectural development for the next generation of NOAA environmental satellite constellations, adapting new technology and space commerce business practices to achieve enhanced performance at lower cost.

Ms. Griffin oversees the execution of NOAA’s commercial weather data program that acquires critical weather data needed to meet NOAA’s mission from commercial providers. Prior to her position in OSAAP, Ms. Griffin directed the 550+-person team responsible for the successful operation of eighteen of the Nation’s environmental satellites along with the production and analysis of science products using the data from those satellites. Ms. Griffin previously served as the Project Manager for NOAA’s largest IT development project, responsible for the design and development of the large, complex ground system NOAA uses to operate the Geostationary Operational Environmental Satellite - Series R (GOES-R) satellites. Ms. Griffin developed her in-depth knowledge of satellite and ground system development and operations while serving in a variety of positions during her extensive career.

As Chief of NOAA’s Ground Systems Division she sustained and modernized NOAA’s satellite ground systems. As the Science Operations Manager for NASA’s Earth Observing System Data and Information System she supervised the operations of NASA’s nine Distributed Active Archive Centers. She has held a variety of NASA Program Management and System Engineering positions. Ms Griffin maintains a strong customer‐focus cultivated during the ten years she served as an Advanced Meteorologist with the United States Air Force. Ms. Griffin holds a Master of Science Degree in Atmospheric Science from the Georgia Institute of Technology along with Bachelor of Science Degrees in both Meteorology and Computer Science.

Dan St. Jean brings more than 27 years of NOAA experience to our team. He spent the first 20 years of his NOAA career as a National Weather Service forecaster at 5 different Weather Forecast Offices across the West, Southeast and New England states. Dan's forecasting experience ranges from fire weather to hurricanes to winter storms and tornadoes. During the latter part of his NWS career, Dan was the science, training and operations officer in Charleston SC and Portland ME, where he not only implemented new training and technology, but also became a noted lecturer on satellite meteorology applications around New England.

A graduate of the NOAA Leadership Competencies Development Program, Dan most recently brought his meteorology and leadership experience to the NESDIS team, finding his latest challenge as a founding member of OSAAP. Dan began the work of bringing the vision of future architecture development and enterprise thinking to NESDIS as the OSAAP lead scientist. In 2016 Dan became the deputy director for OSAAP -- leading the day to day management of the office as well as oversight of budget planning and execution, hiring, contracts and administrative activities. Dan was recently tapped to co-lead both the NESDIS User Engagement Council and the User Engagement Strategic Objective in NESDIS' Strategic Implementation Plan. Dan also facilitates the NESDIS Enterprise Risk Board and serves as Review Board chair for several NESDIS-wide engineering projects.
