Biostatistical consulting
I work with clinicians and health researchers who need rigorous statistical support, from planning a study to preparing results for publication. My background in applied econometrics means I pay close attention to study design, confounding and what the data can and cannot tell you.
What I can help with
- Study design and sample size calculations
- Data cleaning, structuring and record linkage
- Regression modelling and predictive modelling
- Causal inference with observational data
- Tables, figures and statistical methods sections for manuscripts
- Responding to reviewers' statistical comments
