Biography:
| I am a research statistician working in the Clique group in UCD on the analysis of network data. This includes, but is not limited to, social networks. I use approximate Bayesian inference methods such as Variational Bayes. I'm interested in applying rich statistical models to a wide variety of network datasets and in developing efficient, scalable algorithms for this purpose. My Ph.D. thesis concerned the modelling of multivariate, zero-inflated, spatial counts and proportions data as part of a Palaeoclimate reconstruction project. I used traditional Bayesian inference methods such as MCMC and new Gaussian approximation techniques such as the Integrated Nested Laplace Approximation. |
