The simplest model of such data is the Poisson process, with more complicated extensions including renewal processes, Matern repulsive processes and Hawkes processes. The Poisson process also underlies function and measure-valued stochastic processes like Markov jump processes (used in stochastic chemical kinetics, for instance), and completely random measures or Levy processes (used in Bayesian nonparametrics). In this talk, I will show how the latter connection allows the development of flexible models as well as efficient (and exact) Markov chain Monte Carlo algorithms. The resulting models and algorithms have wide applicability; I will consider problems from neuroscience, genetics and biometrics.</span></p>
