Christopher Harms

Data Scientist · Dr. phil. ·

Hi there! I am a Data Scientist, Co-Founder and Managing Director of SKOPOS ELEMENTS. My previous academic research at the University of Bonn was focused on statistical practice and replicability in psychological science. At SKOPOS ELEMENTS, we implement state of the art solutions for data-driven companies — using both statistical methods and cutting edge machine learning. My talks and workshops focus on data science, replicable research methods, and the future of data science in business.

This page is my CV and a list of my academic publications. You find writings on my research and data science stuff over at my blog.
