Somehow, our minds make sense of sensory data in a way that eludes current machine vision systems. We study visual perception in humans using psychophysics and computational models. A secondary interest is in machine vision systems, including deep neural networks. We compare the inferences of humans and machines to gain stronger insights into both biological and artificial seeing.
Topics of current interest include
Ultimately, we aim to understand the computational principles that underlie our brains’ ability to combine sensory inputs to generate holistic perceptual experience.
As part of the Centre for Cognitive Science, we are integrated at the TU-Darmstadt's research priority to advance knowledge in the field of Information and Intelligence (I+I).

We collaborate honestly: we are comfortable telling each other when we don't understand something, we patiently teach through misunderstandings without judgment, and we challenge each other's ideas when we think they're wrong.
Failures and mistakes are an integral part of the scientific process. Be open and honest, transparently discuss, and learn from these for next time. You should never feel pressure to fudge or falsify data.
We strive to be inclusive and equitable. We do not make inappropriate jokes or comments about others based on gender, race, or other personal factors.
We encourage healthy work/life balance and inclusion of lab members with carer duties through clear separation of work and non-work time, and fostering strong time management skills. Lab members are discouraged from being responsive outside their normal work hours.
