Education
Singer received a Bachelor's degree in Astronomy and Anthropology from the University of Colorado Boulder. While there, she decided to pursue research in the fields of astrobiology and planetary science. [4] She studied abroad at Macquarie University in Sydney, Australia, during her undergrad, where she worked at the Australian Centre for Astrobiology studying clouds in Venus' atmosphere (with Dr. Jeremy Bailey), tidal sediments on Earth (with Dr. Malcom Walter), and also continued with her interest in archaeoastronomy. Upon returning to Boulder, she worked with Steve Mojzsis on her honors thesis project about using sediments called cyclic rhythmites to trace the length of a day over millions of years, and a research project on "blueberries" (hematite spherules) and thermal inertia on Mars. [5]
Singer received a Ph.D. in Earth and Planetary Science from Washington University in St. Louis in 2013 working with Dr. Bill McKinnon and Dr. Slava Solomatov; her dissertation was titled Icy Satellite Tectonic, Geodynamic, and Mass Wasting Surface Features: Constraints on Interior Processes and Evolution. [6]
Research
Singer continued as a postdoctoral researcher at Washington University with the Dr. Brad Jolliff and the Lunar Reconnaissance Orbiter Camera team after receiving her Ph.D. In 2014, she joined the New Horizons team at SwRI as a postdoctoral researcher, where she studied the geophysics of Kuiper Belt Objects, particularly cratering physics. [7] At SwRI, she is currently a principal research scientist and Deputy Principal Investigator for the New Horizons Extended Mission.
In 2019, Singer and her team demonstrated from images of craters taken by New Horizons' Long Range Reconnaissance Imager (LoRRI) that small Kuiper Belt Objects (less than one mile in diameter) are rare. [8] [9] [10] [11] [12] The results place constraints on formation and evolution models of the Solar System, suggesting that objects in the Kuiper Belt formed from rapidly collapsing dust clouds rather than incremental collisions of larger debris. [10]
Singer has coordinated and contributed to the 'Women in Planetary Science' blog site since 2009. [13]
Dr. Singer has worked on many planetary bodies throughout the solar system, [14] but primarily: Mercury, the Earth's Moon, Mars, the icy moons of Jupiter, Saturn, and Neptune, Pluto, and other small bodies such as Kuiper belt objects and asteroids.
Her areas of expertise include: [1]
- Geology and geophysics of icy worlds (icy satellites, Pluto, Charon, Europa),
