About

I am a Research Scientist in the AI for Medical Devices team at Haag-Streit, where I develop cutting-edge deep learning solutions for surgical skill assessment, virtual reality guidance, and automated video analysis in ophthalmology. My work bridges AI research and real-world clinical applications, focusing on enhancing surgical precision, improving diagnostic accuracy, and optimizing workflow efficiency in medical imaging and surgical video analysis.
Prior to joining Haag-Streit, I conducted postdoctoral research at the University of Bern’s AI for Medical Imaging lab, where I led projects in domain adaptation, semi-supervised learning, and phase recognition in surgical videos. My PhD research at Klagenfurt University focused on advanced deep learning models for surgical video analysis, including phase and action recognition, real-time anomaly detection, and relevance-based video compression. My work has contributed to AI-driven surgical content retrieval systems currently in use at major hospitals, supporting both clinical decision-making and surgical training.
