I'm doing research using psychophysiological methods, mostly using changes in pupil size or eye movements to investigate cognition and perception. I focus on visual and spatial attention: Where and how do we deploy visual attention over time? Why do we move our eyes the way we do it? This research also includes methodological questions: When do pupils change? Why do pupils change and how can we dissociate possible contributing cognitive factors from another?
Besides these more fundamental questions, I look into ways to apply these insights, e.g., in human factors research and the field of human-computer interaction, in neuropsychology, or for ophthalmological diagnosis.
