👋 Oscar Breiner

👨‍💻 Machine learning engineer and researcher.
🤖 Always curious about how things move, learn, and connect.


M.Sc. Informatics (TUM)
Researching at the intersection of machine learning, vision, and scientific computing,
with focus on 3D perception and physics-informed learning across domains like autonomous driving, space applications, and computer vision.


🧪 Research & Engineering Experience

  • Machine Learning Team Lead - WARR DEDRA Science Group (TUM)
    Leading the Machine Learning Team of TUM’s largest student space organization.
    Developed physics-informed models for space debris impact prediction using ion-based sensor data.
    Contributed to a satellite mission launched in 2024, following earlier work as an Embedded Systems Engineer.

  • Research Assistant - TUM Autonomous Motorsport (Chair of Automotive Technology, FTM)
    Developing 4D radar-only odometry and 3D LiDAR perception for autonomous racing at speeds > 250 km/h.
    Achieved state-of-the-art results beyond current benchmarks; preparing for publication in 2026 and competing at the Autonomous Racing League (A2RL).

  • Research Intern - Computer Vision Lab (Prof. Daniel Cremers, TUM)
    Conducted research on multimodal model merging using subspace parameter compression,
    achieving state-of-the-art performance with reduced compute. Publication planned for 2026.

  • Machine Learning Engineer - BMW Group
    Designing and deploying multimodal ML models that improve perception and simulation performance.
    Built scalable ML-Ops infrastructure on AWS SageMaker, optimizing workflows and cutting operational cost across research teams.

  • Research Intern - Machine Learning Lab (Prof. Stephan Günnemann, TUM)
    Investigated graph neural networks (GNNs) and uncertainty quantification, leading to new insights on ensemble-like behavior.
    Authored a seminar paper reviewing Vision Transformers, focusing on robustness and architectural trade-offs.
