Welcome ...

… to my website. Below you can find my contact information and office address (with directions). In case you are wondering who the heck I am, you could consider reading my (not so really) short profile.

On this site, you can also find my curriculum vitae, a list of my publications and presentations, links to some software I (co)authored, and information about a number of courses I teach on a semi-regular basis (e.g., a meta-analysis course, an introduction to R course, and an ESM data analysis course). I also do regular live streams on R and statistics in case you are into that sort of thing.

You might also be here because of the metafor package (a free and open-source add-on for conducting meta-analyses with the statistical software environment R), which I am the author of. More information about the package and its ongoing development can be found on the metafor package website. If you need help with using the package, see here.


News

2025-07-03: As part of a symposium on recent advances in meta-analysis at the TU University Dortmund, I just gave a talk about location-scale models for meta-analysis. You can find the slides under my presentations.

2025-06-11: I gave a presentation at the Evidence Synthesis & Meta-Analysis in R Conference (ESMARConf) this morning about different ways to visualize the amount of heterogeneity in a meta-analysis using prediction intervals and predictive distributions. You can find the slides for this presentation (and the code for the examples) here and a video of the presentation here.

2025-05-27: Just a gave a talk about a rather simple method for estimating and testing the correlation between two momentary assessments in ESM/EMA data that accounts for subject-level heterogeneity at the 2025 Conference of the Society for Ambulatory Assessment. You can find the slides under my presentations.

2025-04-30: We recently published a paper at Behavioral Research Methods describing the findings from a comprehensive simulation study on the performance of various tests and methods for constructing confidence intervals for the scale coefficients in meta-analytic location-scale models. See https://doi.org/10.3758/s13428-025-02622-5 for further details.
