This was followed by postdoctoral research at Queen’s University Belfast and the Institut d’Astrophysique de Paris before returning to Cambridge in 2007 to work. Jan moved to begin a lectureship at the University of Auckland in 2011. Her general research concerns the lives and deaths of stars, from those in our own Galaxy to those in galaxies at the edge of the observable Universe. Particularly the effects of binary interactions on the lives of binary stars and how these change the appearance of galaxies, galactic habitability, the rates of different types of supernovae and gravitational wave events.
