About Christopher Nunn, Ph.D.

I'm a physicist by training, and a passionate data scientist by profession. During my PhD I studied the dynamics of mitochondrial genomes using empirical tools like DNA sequencing and theoretical tools like probabilistic modeling and stochastic simulations. Throughout this research I gained extensive experience in the analysis, modeling, and visualization of large datasets.Currently i'm applying my data science skill-set to difficult problems in the (re) insurance industry that require AI/machine learning, classical statistics, big data wrangling/engineering, and alternative data.
