Gunnar Pruessner is a Senior Lecturer of mathematical physics at the Department of Mathematics, Imperial College London, London, UK. Before joining Imperial College London in 2007, he held the position of an Assistant Professor at the University of Warwick, Coventry, UK. After receiving his Ph.D. in 2004, he held postdoc positions at Virginia Tech and Imperial College London. His main expertise is in analytical (mostly field theoretical) and numerical techniques in nonequilibrium statistical mechanics. He works in the field of nonequilibrium phase transitions and its applications to biological and man-made systems, considering mostly asymptotic behaviour (i.e. phenomena on large length and time scales). These applications range from surface and crystalline growth to scaling in ecotones. He applies field theoretical techniques extensively, as well as large scale numerics. The main focus of his research is complexity and self-organised criticality (SOC) with the objective to bring to bear the most successful technique of statistical mechanics, namely, renormalized field theory. He was able to relate the largest universality class in SOC to the well-studied quenched Edwards-Wilkinson equation, establishing rigorously for the first time an intimate link between traditional nonequilibrium critical phenomena and SOC. Very extensive computer simulations of the most robust and solid model in SOC, the Manna Model, provide further evidence for the universality and the existence of an epsilon expansion. Recently, he completed a 500-page monograph on SOC, published by Cambridge University Press, in September 2012. In 2009, he was chosen as an Outstanding Referee for Physical Review and Physical Review Letters by the APS.
