- Bayesian hierarchical modelling — structure learning and variable selection in graphical models; geometry-adaptive sampling.
- Time series and regime change — state-space reconstruction, changepoint detection, dynamic factor models.
- Econometrics of value and prices — empirical construction of labour values and production prices without simultaneist assumptions.
- Philosophy of science — probability, dialectics and the foundations of statistical inference.
All twelve are single-authored and single-maintained.
