Probability and Stochastic process is the study of randomness. It is at once a theoretical and abstract subject and one which is highly applied. Probability is both an increasingly core subject in mathematics and has long been an indispensable tool in applied modeling. Probability has been central in a number of recent Fields Medals. Probability is a required tool in topics ranging from modern population modeling to Bayesian statistics to phase transitions.
Probability at Duke spans from the ergodic theory of stochastic PDEs to waves through random media to random graphs and networks to cancer modeling.
