Data Science consultant with 5 years' experience in data analytics. Extensive knowledge of transforming large datasets into meaningful insights. In the last 4 years I have shown affinity with goal-driven work as a PhD researcher. I have investigated the genetics of ADHD, and genetic differences between monozygotic (identical) twins. I have also been active as teaching assistant in this period and deepened my knowledge through courses in R and Python (ML, data-analysis, visualization, data science). Quick learner, teacher, constructive sparring partner. In my spare time I am a semi-professional musician. Playing guitar and drums in two separate bands have improved my public speaking and organizational skills.
