Lukas Stappen doctorate (Dr.-Ing.) in multimodal deep learning was supervised by Prof. Schuller and defended with summa cum laude (engl. with the highest honours) in 2021. He received a M.Sc. in Data Science with distinction from King's College London, UK, in 2017 and joined Prof. Dobson’s group. He (co-)authored 30+ publications (1,7k+ citations, h-index=19) in the research fields of multimodal and language deep learning, with focus on human-centric systems. Further interests are denoising in-the-wild signals and machine learning in healthcare-related domains.
