Mrs. Sandra Irish has 38 years of experience in aerospace working for NASA Goddard Space Flight Center. She is a Group Leader in the Mechanical Systems Analysis and Simulation Branch in the Engineering directorate at Goddard. She is currently the Mechanical Systems Lead Structures Engineer for the James Webb Space Telescope (JWST). Mrs. Irish received a B.S. in Aerospace Engineering from the University of Maryland. She started her career at NASA Goddard working on space flight instruments and spacecraft in the area of structural dynamics, systems analysis, and mechanical testing. She has worked on projects such as Broad Band X-Ray Telescope, Upper Atmosphere Research Satellite, ASTRO-E missions with the Japanese Space Agency, and Cosmic Background Explorer (COBE) in which the science earned John Mather the Nobel Prize for Physics. She has been working on JWST for 15 years and runs a structural dynamics team responsible for launch and transportation load environments, mechanical testing, and thermal distortion and jitter performance on-orbit for the telescope. In addition to her various engineering positions, Mrs. Irish mentors engineering students and is involved in public outreach activities that help inspire young engineers. She is a member of the Society of Women Engineers and has developed a Women Engineers Group at NASA Goddard entitled WEST-Women Engineers in Space and Technology. Mrs. Irish has been the recipient of Robert H. Goddard Exceptional Achievement Award for Engineering and has received the NASA Agency Award for Outstanding Leadership for her work on JWST.
