… 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.

2023-09-10: I have finally managed to arrange another round of the ESM Data Analysis Course, which will take place December 6-8, 2023. See the link for more information about the course and how to register if you would like to participate.

2023-08-27: I just gave a brief demo of the metafor package as part of the symposium 'Recent Advances in Meta-Analysis: Methods and Software' which was held at the University Medical Center Göttingen in Germany. If you are interested in the slides, you can find them here.

2023-08-07: New dates for the Open Online R Stream have been scheduled. I've also updated the dates for my office hours.

2023-07-30: I recently attended two conferences, the annual meeting of the Society for Research Synthesis Methodology and the European Congress of Methodology, where I gave presentations on some recent updates to the metafor package and on methods for obtaining confidence intervals for the pseudo-R² statistic in meta-regression models. You can find the slides for those presentations here.
