Professor Thomas Nowotny
Computational neuroscience and bio-inspired AI
In our group we use computational and hybrid systems approaches to better understand the properties and function of sensory and motor systems as well as taking inspiration from the brain to build better AI. This involves three main areas of research:
1. bio-inspired machine learning and computational neuroscience models of (mainly olfactory) systems and,
2. using GPU technology to accelerate the simulation of Spiking Neural Networks
3. hybrid systems research for active closed-loop probing of neural circuits.
I am happy to supervise a PhD in any of these three areas. Work on olfaction could include continuing the work on models of odour sensing in the peripheral olfactory system of insects. For the computationally minded, large scale simulations of olfactory systems and/or networks for AI applications inspired by insect brains with GeNN are an option.
Collaborations within Sussex Neuroscience: We have a long-standing collaboration with George & Ildiko Kemenes, Kevin Staras and Paul Graham and are also now working with Claudio Alonso.
