dr. L. Spek (Len)

I am a Lecturer and Post-Doc working on Delay Equations arising from Neural Field Models in Neuroscience. I use Functional, Spectral and Non-Linear Analysis to investigate the qualitative behaviour of different variants of these models.

I am also interested in recent developments in the field of (Artificial) Neural Networks and how they are related to Dynamical Systems Theory and Mathematical Neuroscience.
