Mary Anne Limbach is an astrophysicist at Texas A&M University. Her research focuses on exoplanet characterization and exomoon detection methods. She is lead scientist and optical engineer for the Exoplanet Transmission spectroscopy Instrument (ETSI) instrument being built at TAMU. ETSI will be the first precision instrument capable of surveying hundreds of exoplanet transmission spectra from a modest (2-4 m), ground-based observatory. Mary Anne is also part of the Gemini Planet Imager (GPI) consortium and lead optical engineer for the design upgrades to the integral field spectrograph (IFS). Her goal is to implement several novel instrumentation techniques to improve exoplanet detection and photometric precision. Finally, she is working on several novel techniques for exomoon detection with the objective of confirming the first moon outside our solar system in the near future.
