Royal Society University Research Fellow (2014-2023)

I'm currently highlighting the following

• seminar: Algorithms & Computationally Intensive Inference

---

Research Interests

• general: stochastic simulation, computational statistics, Bayesian statistics
• specific: probabilistic algorithms, MCMC, adaptive MCMC, perfect simulation, analysis of algorithms, exact inference for SDEs, intractable likelihood problems
• I welcome PhD and postdoc applications in these areas from motivated researchers with strong technical background. Please get in touch if interested.

Teaching

• Office hours (term time only): Wednesday 9:30-10:30 and Thursday 10:30 - 11:30 (Teams or in person)
  If you would like to talk over Teams, just give me a call – instructions are here (link). If I am already in a call then drop me a message in Teams chat and I will call you back.
• In 2023/24 I am teaching ST232.
• Past teaching: In 2018/2019 I was teaching OxWaSP module 1 on statistical computing with Robin Evans.
  See the course webpage here.
• Recently I gave a course on exact simulation of diffusions at the Computation and Modelling summer school in Wroclaw, July 4-8, 2022.
