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.

Research

While I love working on cutting edge technologies, I am most intested in bringing them into products.

I have written over 15 research papers and have over 10 patents. Visit Google Scholar for a complete and up-to-date list.

Talks / Lectures / Podcasts

I am regularly giving talks and keynotes about technology in general. Feel free to reach out.

Porsche PhD Podcast

At Porsche, I have initiated, produced, and together with my fellow head of the PhD network Mohamed Kari, co-hosted the Porsche PhD Podcast where we interviewed Porsche PhD students company-internally on their research and Porsche executives on the role of PhD research for innovation.

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.
