I'm an applied statistician with strong background in psychology and behavioral science (MSc. + 5 years' experience in behavioral science consulting). Proficient in data wrangling and visualization in R, data modelling and inferential statistics (frequentist and Bayesian), causal inference, survey design, experimental design—in short: gleaning practical and scientific insights from data. When working with me, you can expect: 👨🔬 Scientific and statistical rigor—I take analyses seriously and don't shy away from learning new skills when required for a specific job. 💎 Transparency—by default, I script my analyses in R code which you can inspect if desired, or show to others who may wonder how the stats were produced. 💡 Clarity—I'm comfortable communicating complex results to lay audiences and will work with you to ensure you understand how the analyses translate into actionable insights. I'm comfortable working alone as well as with a team. I also love advising motivated people who find themselves stuck but want to carry out analyses themselves—if that's you, let's chat!Data Visualization
