Probability and Applications Group

Probability is both a fundamental way of viewing the world, and a core area of  mathematics. Probability theory is concerned with the analysis of mathematical models of random phenomena, as occur in many  branches of science.  The group Probability and Applications at QMUL is engaged in numerous research activities, including  stochastic processes, statistics, random discrete structures, random matrices and stochastic optimisation, as well as in applications of probability to  statistical physics, modelling of epidemics, networks, financial engineering and other areas.
