A photograph of Hil Meijer I studied Physics and Mathematics in Utrecht. I continued there with Yuri Kuznetsov and Ferdinand Verhulst as my advisors. After my Ph.D. in Mathematics in december 2006. I then moved to the University of Twente to work as an assistant professor in the chair Applied Analysis of prof.dr. S.A. van Gils.

My research on Numerical Bifurcation Theory deals with theoretical descriptions and numerical tools for bifurcations in ODEs and maps. The tools classify the dynamics near a bifurcation and allow initialization of nontrivial bifurcation curves. I am an active developer of the matlab toolbox MATCONT and have taught several related tutorials.

My research on Neurostimulation centers around the idea that a stimulus steers neuronal dynamics. In neurodegenerative contexts such as epilepsy and Parkinson's disease, there is undesirable oscillatory dynamics that may be quenched by a suitable stimulus. Understanding the effect of such stimuli may lead to improved techniques for Deep Brain Stimulation. In addition, stimulation offers a window to study and uncover neurophysiological processes. The SPES protocol, for instance, may reveal epileptogenic networks. Psychophysics offers an interesting window into pathology and cognition. I strive to develop computational models of neuronal dynamics that explain data and have a clinical relevance.
