Katie did her Masters in 2002 in Gerd Juergens' Lab in Tuebingen, Germany, studying how pairs of ARF and Aux/IAA transcriptional regulators provide specificity in the auxin response. She started her PhD work at the Max Planck Institute for Developmental Biology (Director Detlef Weigel, Tuebingen) where she worked in Phil Wigge's group studying FT and the mechanism by which it activates flowering. Katie continued these studies when the group moved to the John Innes Centre (JIC, Norwich, UK). After a baby break she continued as a postdoctoral researcher at JIC, working on modeling developmental switches in Arabidopsis. After her second child, Katie took up her post at SLCU as a Career Development Fellow in Autumn 2013.

Wild type and mutant plant show differing growth behaviour at 27ºC, with mutant being unresponsive to high temperature (right).  Growth rate differs between day (yellow bar top left and night (back bar top left corner). Movie courtesy of: C. Marthino
