Experience: 
Janet A. Mattei is an internationally recognized astronomer specializing in the field of variable stars, particularly eruptive (cataclysmic) and pulsating (long period) variables. She has been the Director and the scientific representative of the American Association of Variable Star Observers (AAVSO) since 1973. As the Director of the AAVSO, she is responsible for the quality control of of the AAVSO International Database - the world's largest optical variable star database with over 10 million observations going back to 1911 - mostly amateur astronomers - worldwide. She has coordinated over 600 observing programs between amateur and professional astronomers using large, ground-based telescopes in well-known observatories and space satellites. She has provided observations from the AAVSO International Database for over 600 projects for multi-wavelength data correlation. 
Dr. Mattei is keenly interested in education and has provided guidance in setting up over 200 observing programs in schools and for student science projects. She has been the principal investigator of two NASA-funded IDEA grants for the AAVSO education program: "Partnership in Astronomy" and co-director of AAVSO's major education project: Hands-On Astrophysics: Variable Stars in Math, Science, and Computer Education, funded by the National Science Foundation. She has played a key role in amateur astronomers being given observing time on NASA's Hubble Space Telescope (HST), and served in the working group to choose the amateur astronomers who would observe with HST from 1986 to 1995. Dr. Mattei has published over 180 papers on variable stars and related topics, mostly in refereed journals.
