I take a quantitative approach in the interpretation of core biological concepts. By using formal tools from statistical learning and information theory with conceptual analysis, I develop new frameworks that may enable a deeper understanding and application of technical notions. I have written on concepts from behaviour genetics, population genetics, evolutionary psychology and quantitative genetics, with particular emphasis on the analysis of heritability, population structure, genetic information and epigenetic transmissibility. I am currently a postdoctoral researcher at the Max Planck Institute MIS, Leipzig. I believe that an interdisciplinary approach can greatly benefit both mathematical biology and philosophy of biology. My current focus concerns the theme of biological information and in particular, understanding genetic structure and evolutionary processes from an information-theoretic and statistical learning perspective, also utilizing ideas from gambling and portfolio theory.
