Jessie Christiansen is an Australian
Education
In 2002 Jessie Christiansen completed a Bachelor of Science (Advanced Studies) in physics and mathematics at Griffith University, Brisbane. She then continued her studies to receive a BSc first class honours in Astronomy at the Australian National University, Canberra.[1] She completed a PhD at the University of New South Wales in 2007, under the supervision of Michael Ashley.[2][3] Her PhD required observations at the Automated Patrol Telescope at Siding Spring Observatory.[4]
Career
After Christiansen's PhD, she worked as Postdoctoral Research Fellow at the
Christiansen uses Citizen Science and the Zooniverse to help in her quest for exoplanets using the Kepler Space Telescope K2 dataset.[7][8] She worked with Professor Ian Crossfield at MIT to ensure that the K2 data was made public, and in January 2018 announced the discovery of 5 massive exoplanets orbiting the sun-like star K2-138.[9][10][11][12][13] The exoplanets make up the longest chain of synchronised exoplanets ever discovered, orbiting in near-perfect resonance to their star.[14][15] In an interview with the BBC, Christiansen spoke about the importance of crowdsourcing research projects "people anywhere can log on and learn what real signals from exoplanets look like, and then look through actual data collected from the Kepler telescope to vote on whether or not to classify a given signal as a transit, or just noise".[16]
Alongside being the plenary speaker at academic conferences, Christiansen gives public talks about her research.[17][18] She has returned to her alma mater, ANU, to discuss her research "Characterising the Kepler Survey Completeness".[19] In July 2018 Christiansen won the NASA Exceptional Engineering Achievement Medal for her work on the Kepler planet sample.[20]
Public engagement
Christiansen appeared on the
Her writing has appeared on popular science websites, including the New Scientist,[25] Smithsonian Magazine,[26] and BBC News.[27] In 2015 Christiansen joined 278 other scientists in a letter to the New York Times to object to their article that minimized the trauma of people who accused Professor Geoff Marcy of sexual advances.[28][29]
