After finishing her PhD at the Swedish University of Agricultural Sciences, Hanna came to the Taylor lab in September 2002 for a two-year post-doc. Her research focused on selection processes in the human pathogen Coccidioides immitis.

Hanna returned to Sweden in November 2004 and is currently a professor at Uppsala University.
