Medical Statistician



I'm a medical statistician interested in the design, analysis and interpretation of clinical trials.

Specific research interests include:

  • group sequential trials
  • multiple hypothesis testing
  • adaptive designs
  • survival analysis

Since February 2020 I have been working in the Statistical Methodology Group at Novartis in Basel.
