As she now works in the field of aeronautics and astronautics, she has stated how she enjoys studying the applications of electrical engineering in helping to further explore the Earth and beyond.
Additionally, it was there that Cahoy continued combining her passions for electrical engineering and aerospace as she studied how we could learn more about weather on planets beyond Earth using instrumentation like satellite radio signals.
[3] Cahoy started her career at MIT in June 2010 on the research staff in Earth and Planetary Sciences affiliated with the NASA Goddard Space Flight Center.
She directs the STAR lab at MIT which is focused on four key areas: weather sensing, connectivity, exoplanet detection and characterization, and nanosatellite technology.
Her lab has contributed to missions including NASA's Transiting Exoplanet Survey Satellite (TESS) and Laser Guide Star for Large Aperture Segmented Space Telescopes (LGS).
[4] Her team has flown 3 CubeSats so far, and the success has proven that these smaller scale satellites can oftentimes provide comparable data to that of larger instruments or spacecraft.
The work studies "Super Earths" and models to predict "their transmission, thermal emission and reflected light spectra.
"[10] Aside from her influential research in the field of aerospace engineering, Cahoy has been widely recognized for her incredible compassion and understanding when mentoring her graduate students.
As a 2020 recipient of the Committed to Caring Award at MIT, one of Cahoy's nominators wrote about how she “launches more space missions than any other AeroAstro professor, yet remembers the needs of all her graduate students.”[11]
