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 modeling, and applied machine learning in order to elucidate the fundamental computations allowing us to make sense of our environment through touch.

TouchSim is a Matlab package that simulates spiking responses from thousands of tactile afferents terminating on the palmar surface of the hand to arbitrary indentation of the skin (see Saal, Delhaye et al., PNAS, 2017 for details). The package is freely available for download.
I am the course director for the MSc Cognitive Neuroscience and Human Neuroimaging program. I also teach on the following modules:
- PSY6309: Mathematical Modelling and Research skills (module organizer)
- PSY6308: Computational Neuroscience 2 - Theoretical Models
- PSY1002: Cognitive Psychology I
- PSY2002: Cognitive Psychology II
