Debra Ann Fischer is a professor of astronomy at Yale University researching detection and characterization of exoplanets. She was part of the team to discover the first known multiple-planet system.[1][2] She also worked with Dr Tabetha Suzanne Boyajian.

Research and career[edit]

Fischer has co-authored over 100 papers on dwarf stars and sub-stellar mass objects in the galactic neighborhood, including many on extrasolar planets. Her work "The Twenty Five Year Lick Planet Search" is summarized in a paper by Fischer, Marcy & Spronck 2014. She is a principal investigator with the N2K Consortium searching for exoplanets. She co-leads the planet search team with Gregory P. Laughlin and Jessi Cisewski looking for extrasolar planets.[2][3] She was the primary investigator for Chiron, the CTIO High Resolution Spectrometer.[4] In 2011, she started the Fiber-optic Improved Next-generation Doppler Search for Exo-Earths with the Planetary Society, an instrument that will help planet hunters find Earth-like extrasolar planets.


Fischer received her degree from the University of Iowa in 1975, a masters of science from San Francisco State University in 1992, and her PhD from the University of California at Santa Cruz in 1998.[5][6]
