I am currently a PhD candidate at Shravan Vasishth's lab and a researcher within Project B03 (‘Modelling the interaction between eye-movement control and parsing processes’) of the SFB 1287 Limits of Variability in Language at the University of Potsdam, Germany.

I am interested in the underlying mechanisms of human sentence processing. My current project investigates similarity-based retrieval interference during real-time sentence comprehension in English as well as German, using the eyetracking-while-reading method. This work also examines participants’ individual differences in cognitive abilities and the influence of task demand on reading behaviour.

The English experiments will be conducted in collaboration with Prof. Brian Dillon at UMass Amherst, MA, USA.
