• Bayesian inference;
• Analysis of capture-recapture data (including analysis of individual heterogeneity and random effects models; spatially explicit capture-recapture; incorporating memory; applications in ecology and epidemiology);
• Multiple systems estimation and their application to hidden population, including modern slavery and problem drug users;
• Integrated data analyses
• Missing data;
• Hidden (semi-)Markov models/state-space models and their applications to ecology and healthcare data;
• Efficient model-fitting tools.
