Portrait of Long Nguyen

I am a researcher at KE:SAI, advised by Prof. Dr. Andreas Geiger in the Autonomous Vision Group at the University of Tübingen and Dr. Kashyap Chitta in the Physical AI Lab at the ELLIS Institute Tübingen.

Portrait of Long Nguyen

My research focuses on end-to-end driving policies, which learn perception and planning jointly from raw sensor data. Two simple questions guide my work:

  1. What do imitation-learned policies really need to excel in closed loop?
  2. What makes a driving benchmark predictive of real-world performance?

I believe progress is best measured in closed loop, which makes simulation essential. I also believe in open research: sharing code, data, and models lets us build on each other's work.

I am always open to collaborations on policy learning, closed-loop benchmarking, and driving simulation. The best way to reach me is by email or LinkedIn.
