Henrik Jeldtoft Jensen is a professor of mathematical physics and leader of the Centre for Complexity Science at Imperial College London. He works on the statistical mechanics of complex systems. He has worked on the dynamical properties of condensed matter systems and developed the tangled nature model of evolving ecosystems, which is currently used to develop the tangled finance approach. His two books on complexity science Self-organized Criticality and Stochastic Dynamics of Complex Systems (with Paolo Sibani) have attracted very broad interest. Henrik Jensen has more recently worked on brain dynamics and structure by analyzing fMRI and EEG data, beside of various research projects in evolutionary ecology and finance and economics.
