… 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.

2023-03-19: A new version (4.0-0) of the metafor package has been released on CRAN.

2023-03-08: The next book to be covered on my weekly live streams is Regression and Other Stories by Gelman, Hill, and Vehtari. I will intersperse this with some 'Introduction to R' sessions (see the schedule).

2023-02-17: New article out on how to deal with missing standard deviations in meta-analyses of response ratios (i.e., log transformed ratios of means): https://doi.org/10.1111/ele.14144.

2023-02-06: The 2023 Evidence Synthesis and Meta-Analysis in R Conference will take place March 27-31. The conference is completely free (voluntary donations welcome). More details here. On March 24th, I will give a free pre-conference workshop on meta-analysis with R.
