Dr. Margaret Dominguez has been an optical engineer at NASA Goddard Space Flight Center since 2008. 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 conducted optical design, alignment and metrology on the ground support equipment for the James Webb Space Telescope’s Integrated Science Instrument Module. Most recently she has been working on the aligning, assembling and testing the grism (grating prism) component of the Wide Field instrument on the Roman Space Telescope. Margaret is also a research associate at the National Institute of Standards and Technology (NIST) where she collaborates with their Center for Nanoscale Science and Technology (CNST). In her spare time Margaret is a STEM advisory board member at the Children’s Science Center in Fairfax Virginia and her hobbies include doing educational outreach to teach through various platforms, mostly elementary and middle school girls, about optics both locally and internationally. Margaret enjoys traveling and when she is not at NASA, she teaches Jazzercise (dance fitness exercise instructor), watches movies and goes for walks with her husband, who is also an optical engineer at NASA Goddard.
