CV

Christian studied Psychology at Bielefeld University, followed by doctoral studies at the Cluster of Excellence Cognitive Interaction Technology (CITEC). He obtained his PhD (Dr. rer. nat.) in 2017 for a thesis on episodic visual cognition, object recognition, and short-term memory. For his thesis, he received the Dissertation Prize of the Westphalian-Lippian University Society. Currently, he is a postdoctoral researcher at CITEC and in the Neuro-cognitive Psychology Group at Bielefeld University.

Current Main Research Interests

Christian studies visual attention, the cognitive mechanisms enabling humans to selectively process important objects in the visual scene for perception and the control of behavior. More specifically, he is interested in how attention operates across distinct episodes of cognitive processing and how this depends on the observers' momentary state of alertness. To study these processes, he uses psychophysical experiments in combination with eye tracking and pupillometry, and develops new methods for visual stimulus presentation on gaming monitors.
