David Bethge, Dr.
I am an Executive Project Manager & Strategist at NXP Semiconductors. I love managing and executing projects or strategic initiatives in the field of technology. I am eager to connect with fascinating individuals and learn more about them.
Previously, I worked at Meta/Facebook as a researcher for machine learning and novel sensors for AR/VR input.
I also worked as a Machine Learning Engineer and Innovation Manager for Emerging Technologies at Porsche.
I obtained a PhD (Dr. rer. nat.) in Computer Science at LMU Munich advised by Albrecht Schmidt.
I have a masters and bachelors degree in Industrial Engineering and Management from KIT in Germany. In 2018/2019 I was a visiting researcher at Carnegie Mellon University (CMU) with Artur Dubrawski.

Personal Life
I come from a family of engineers and entrepeneurs. I grew up in Germany and Austria traveling a lot while I was a kid. I was raised with a strong emphasis on education, lifelong learning, kindness, and the strong desire to think in-depth about the world around us.
In my free time, I find joy climbing in the alpes with my friends and surfing the waves along Europe's coastlines.
