Hi, I'm Leonard Wagner, a ML Engineer and Computer Science Student at UZH & ETH Zurich. Hi, I'm Leonard Wagner, a ML Engineer and Computer Science Student at UZH & ETH Zurich and I currently work as a Machine Learning / Cloud Engineer at Siemens.
I build machine-learning systems and the software around them. I'm
happiest somewhere between a terminal and a treeline: training models,
writing C++ and Python, and otherwise skiing, hiking, climbing, and
mountaineering. 
- GraphHands/
currently working on A graph-based pipeline that learns a shared latent space between human and different robot hands for cross-embodiment manipulation.
- Medical RAG Assistant/
A privacy-first clinical decision support system — manage patient records, transcribe consultation audio, and answer free-text medical questions with cited, RAG-grounded answers, all running fully locally so no patient data leaves the machine.
- Monocular Visual Odometry/
A robust monocular visual odometry pipeline that estimates camera trajectory from a single video stream — combining Essential-Matrix initialization, bidirectional KLT tracking, two-stage PnP-RANSAC pose estimation, and continuous landmark triangulation, tuned to run on KITTI, Malaga, Parking, and a self-recorded handheld sequence.
- MRI PoPE-ViT/
A Vision Transformer pipeline for brain-tumor MRI classification that pits Polar (PoPE) against Rotary (RoPE) positional embeddings to test whether explicitly decoupling 'what' from 'where' improves diagnosis — benchmarked against pretrained and convolutional baselines.
