I am a Senior Researcher at DFKI and RPTU. I am interested in multimodal AI, generative models, and physics-informed neural networks with a focus on industrial applications, such as human activity recognition using wearable sensors, predictive maintenance, remaining useful life prediction of Lithium-ion batteries, virtual try-on for online clothing shopping, and biomedical imaging.
