Barbara Grofic

Program Manager


Barb is the Program Manager for the Astrophysics Project Division, which includes the Hubble Space Telescope Operations and Space Science Mission Operations and the Program Director of the PhysCOS/COR Program Office, which includes the ATHENA and LISA studies currently in pre-formulation as well as the management of the Strategic Astrophysics Technology Program. She collaborates with the Exoplanet Explorations Program at the Jet Propulsion Laboratory and the Astrophysics Strategic Missions Program at NASA Headquarters to prepare NASA to implement the results of the 2020 Decadal Survey on Astronomy and Astrophysics.

Barb has over 30 years of NASA technical management experience, including system upgrades to the Hubble Space Telescope’s control center for the spacecraft’s multiple servicing missions, and branch head and associate division chief in the Information Systems and Systems Engineering Divisions, including the Software Engineering Branch at the Wallops Flight Facility. She led the creation of the Program Systems Engineering office for the Geostationary Operational Environmental Satellites (GOES-R) and then served as Lead Technical Authority for the Earth Systematic Missions Program (ESMP). She has also provided leadership as the Assistant Director for Program Support in the Science & Exploration Directorate and as the Deputy Program Manager/Technical for the JPSS Program.

Barb earned a B.A. in Mathematics & Astronomy from Smith College and an M.S. in Computer Science from Johns Hopkins University. She lives with her husband Barry and rescue dogs Jake, Miranda, and Nova and, enjoys golf, cruising in their 1966 Corvair, and visiting with their seven grandchildren.

Dr. Opher Ganel

Program Technologist/Systems Engineer


Dr. Ganel is currently Program Technologist/Systems Engineer (SE) at the Astrophysics Projects Division, as well as Production Lead, editor, and co-author of the Program Annual Technology Reports (PATRs) for the Physics of the Cosmos (PhysCOS) and Cosmic Origins (COR) Program Offices.

Opher began his career in academia, working in high-energy physics. His research experience includes particle detector R&D at Texas Tech University, helping develop the concept for the very forward calorimeter of CERN’s CMS experiment that can survive 10 Gigarads; recommissioning the Meson Test beamline at Fermilab for the CDF detector upgrade effort, increasing usable yield 10-fold; and after leaving Texas in 1997, joining the University of Maryland Cosmic-Ray Physics group where he was Co-Investigator (Co-I) on the ATIC and CREAM balloon experiments, serving as de-facto Instrument Manager (IM) and Instrument Systems Engineer (ISE) for CREAM.

After leaving academia in 2009, Opher served as Co-I and SE on the Firefly CubeSat mission; capture manager/IM on in-house GSFC proposal efforts; and ISE at GSFC’s Instrument Development Lab (IDL), supporting studies spanning Earth, Planetary, and Astrophysics instrument concepts.

Opher brings 30 years of experience in cutting-edge science and technology work in collider experiments, as well as sub-orbital and satellite projects; leading multi-disciplinary and international teams; and serving as an effective interface between members of management, science, and engineering teams.

Opher holds an MSc in theoretical physics (Green-Schwartz Superstring theory) and a PhD in experimental high-energy physics (Searches for Standard Model and Minimal SuperSymmetric Model Higgs Bosons with the OPAL Detector at LEP), both from the Weizmann Institute of Science.

Stephanie Clark

PhysCOS/COR Program Support Manager


Stephanie began her career at NASA working for the James Webb Space Telescope (JWST) as a Project Support Specialist. During her three years on JWST, Stephanie provided administrative support including travel and meeting coordination to her customers. On occasion, she would volunteer for various outreach events both at Goddard Space Flight Center and off site. Stephanie realized that her true passion was working with the public and supporting these outreach events. She recently transitioned to support the Astrophysics Projects Division and the Hubble Space Telescope in doing just that. Currently, Stephanie helps to plan various conferences throughout the year, coordinate and attend outreach events, as well as design and produce outreach materials for the public.
