About Ellen Stofan

Ellen Stofan, a celebrated planetary scientist, astrobiologist, and science communicator, has made significant contributions to our understanding of the solar system and the search for extraterrestrial life. Born on November 15, 1960, in St. Louis, Missouri, Ellen's passion for space was ignited at an early age by watching the Apollo moon landings. Ellen earned her undergraduate degree in geology from the University of California, Berkeley, and a Ph.D. in geological sciences from Stanford University. Her doctoral research focused on the geologic history of Mars, using data from the Viking landers. Throughout her career, Ellen has held prominent positions at NASA's Goddard Space Flight Center, including serving as Chief Scientist from 2013 to 2016. During this time, she played a crucial role in planning and executing numerous missions, including the Kepler mission, which discovered thousands of exoplanets, and the Mars Rover program. Ellen is also known for her advocacy for gender equality in science. She has been vocal about the underrepresentation of women in STEM fields and has been a strong advocate for increasing diversity within NASA. In 2019, Ellen became the first woman to serve as the John Evans Professor of Space Science at the University of Colorado Boulder. Her current research focuses on astrobiology, particularly the search for habitable exoplanets and signs of life beyond Earth. Ellen's quotes reflect her dedication to science and her belief in the power of exploration. One of her most famous quotes is, "Science is not a boy's game. It's not a girl's game. It's everyone's game. It's about asking questions about the world, and trying to understand it." This sentiment has inspired countless young people to pursue careers in science and space exploration.
