Tim Tiefenbach

Senior CX Data Scientist

Hi, I'm Tim!

I am a data scientist working in insurance with a focus on customer satisfaction and customer experience. I enjoy working along the whole data science pipeline. From importing and cleaning data, to creating reports, visualizations and dashboards, to building and training models. While R is my everyday work horse for most jobs, I am getting deeper into python for specific tasks such as NLP.

Before becoming a Data Scientist, I was a post-doc researcher on happiness and life satisfaction in Japan. I have written numerous scientific publications at the intersection of psychology and economics and have presented my research at over 20 international conferences.

More about me

I was born and raised in Wiesbaden, a medium-sized town in proximity to Frankfurt (Germany).

Studies

During my Bachelors and through part of my Masters I lived in the beautiful village of Bayreuth, in northern Bavaria, where I studied "Philosophy and Economics". During that time I also spent two and a half years as a research student at the Gakushuin University in Tokyo, where I significantly improved my Japanese language skills, in addition to studying applied economics and statistics.

PhD

Returning to Germany I decided to pursue my academic career a little further. I wrote my doctoral thesis on the research program of economics and its most recent critiques (e.g. heterodox economics) and advancements (e.g. happiness economics).

Post-doc

Upon completing my doctorate, I became a post-doc research follow in Japan by a lucky twist of fate. This position allowed me to combine my passion for Japan with my background in statistics and happiness economics.

Industry

After becoming a father and with my term as researcher coming to an end, it was a good time to transition from academia to industry, and to relocate back to my hometown Wiesbaden. Here I'm working as a Senior CX Data Scientist in insurance, applying happiness economics to improve customer experience and satisfaction.
