Dr. Margaret Dominguez
Optical Engineer @NASA Goddard Space Flight Center
Dr. Margaret Dominguez is an optical engineer at NASA Goddard Space Flight Center. She earned her B.S in Physics from the Universidad de las Americas Puebla in Mexico and her M.S. and Ph.D. in Optical Sciences from the University of Arizona. Margaret has been working at NASA since 2008, when she started as a summer intern. Margaret has conducted optical design, alignment and metrology on the ground support equipment for the James Webb Space Telescope’s Integrated Science Instrument Module (ISIM). She also carried out spectroscopic measurements on witness samples which were collected off of the Hubble Space Telescope. Most recently she has been working on the Roman Space Telescope (RST), where she is building the grism (grating prism) instrument, a slitless spectrograph on board the telescope which will survey emission-line galaxies when it launches in 2025. She has completed alignment, assembly and testing of the prototype units of the grism and is currently working on the flight unit.
