Thomas Nowotny

Computational neuroscience

In our group we use computational and hybrid systems approaches to better understand the properties and function of sensory and motor systems. This involves three main areas of research:

  1. computational neuroscience models of olfactory systems and bio-inspired machine learning, 
  2. using GPU technology to accelerate the simulation of brain circuits 
  3. hybrid systems research for active closed-loop probing of neural circuits.

I am happy to supervise a lab rotation and 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. Finally, in hybrid systems research we are working on a methodology to build faithful conductance-based models of individual cells in the lab without the use of chemical blockers. This work would involve both programming and electrophysiology.

Collaborations within Sussex Neuroscience: We have a long-standing collaboration with George & Ildiko Kemenes, Kevin Staras and Paul Graham and are also now starting to work with Claudio Alonso.
