- Profile
-
I am a Cognitive Scientist and run the Active Touch Laboratory. I studied Cognitive Science at the University of Osnabrück, Germany and then obtained my MSc and PhD in Neuroinformatics at the University of Edinburgh. I was then a postdoctoral scholar in Sliman Bensmaia’s lab at the University of Chicago, before joining the University of Sheffield to set up my own lab. For most of my career I have worked on the sense of touch, using methods from computational neuroscience, robotics, and machine learning.
- Qualifications
-
- BSc Cognitive Science (Osnabrueck, Germany)
- MSc Neuroinformatics (Edinburgh)
- PhD Neuroinformatics (Edinburgh)
- Research interests
-
I work on mathematical models of sensory coding and perception; my main research area is the sense of touch, where I use human psychophysics, computational modelling, and applied machine learning in order to elucidate the fundamental computations allowing us to make sense of our environment through touch.
