## Overview

#### Research summary

My primary lines of research is applied statistics. I am interested in statistical modeling (in particular cognitive modeling), statistical cognition, and the philosophy of statistics. I am broadly interested in how researchers understand and use statistics, and how their use of data and statistics can be improved.

I also author scientific software (see my GitHub page for details).

#### Teaching summary

I teach reasoning and decision making at the undergraduate level, and research methods and applied statistics at both the undergraduate and postgraduate level. I also regularly give workshops on statistical topics, such as Bayesian methods.
