Tasker joined Columbia University as a postdoctoral research assistant , where she worked on simulations of star formation that incorporated feedback from supernovae .[ 4] She has investigated whether stellar feedback results in the death of Giant Molecular Clouds .[ 5] She spent three years at the University of Florida as the Theoretical Astrophysics Postdoctoral Fellow, before moving to McMaster University as a CITA National Fellow in 2009.[ 6]
Tasker's research investigates how stars form in disc galaxies using computer simulations .[ 7] She looks at how galaxy structure impacts the formation of stars, and how star formation drives galaxy evolution.[ 7] She has argued for the need to evaluate the language around exoplanet ranking metrics.[ 8] She joined Hokkaido University as an international tenure-track academic in 2011.[ 7] She won the Hokkaido University President's Award for Education in 2014, 2015 and 2016.[ citation needed ] She was appointed to JAXA , the Japan Aerospace Exploration Agency , as an associate professor in 2016,[ 2] [ 9] working on hydrodynamical models of star and planet formation.[ 9] [ 10]
Tasker is also a popular science writer. She has written for Scientific American , How It Works , Space.com , The Conversation and Astronomy .[ 11] [ 12] [ 13] [ 14] She has presented popular science lectures at the Communicating Astronomy with the Public conference, the Royal Institution and American Museum of Natural History .[ 15] [ 16] [ 17] In 2015, Tasker presented How Did We Begin at TEDx Hokkaido University .[ 18] She has spoken about the work of the Earth-Life Science Institute to the general public.[ 19]
In 2017 Bloomsbury Publishing released Tasker's first book, The Planet Factory .[ 20] The book was described as "brilliantly written" by Physics World [ 21] and "splendidly readable and authoritative" by Caleb Scharf .[ 20]
Tasker co-authored and edited Planetary Diversity: Rocky planet processes and their observational signatures , an ebook aimed at space science researchers. It was published as a joint venture by the American Astronomical Society and the Institute of Physics in 2020.
