Lorenz Gärtner
I currently work on data analytics methods and statistics in particle physics. My research focusses on accelerating science, bringing us new breakthroughs faster.
I hold a PhD in Physics from the LMU in Munich, I have worked in the German parliament as scientific advisor, and at the International Atomic Energy Agency.
In my free time, I get excited about brainstorming how to deal with the impact of AI, fighting climate change, travelling, climbing and mountaineering.
