Dr. Alexander von Lühmann

Research Group Lead

Alexander von Lühmann is currently the head of the independent research group “Intelligent Biomedical Sensing (IBS)” at BIFOLD, Machine Learning Dept, TU Berlin. He is also a visiting researcher at the Neurophotonics Center of Boston University (BU NPC) and Chief Scientific Officer at NIRx Medical Technologies. Previously, he was R&D director at NIRx, post-doc at BU NPC, visiting researcher at the Martinos Center of Harvard Medical School in Boston, USA, and Chief Technology Officer of Crely, a US-Singapore-based healthcare startup. He received his PhD (Dr.-Ing.) with distinction in 2018 from Technische universität Berlin (TU Berlin) and the M.Sc. and B.Sc. degrees in Electrical Engineering from Karlsruhe Institute of Technology (KIT) in 2014/11.

At the Intelligent Biomedical Sensing(IBS) Lab, Alexander von Lühmann research focuses on machine learning and instruments for comprehensive brain-body monitoring. The IBS lab develops miniaturized wearable neurotechnology and body-worn sensors for unobtrusive monitoring of the embodied brain in the everyday world. It uses machine learning on the multimodal sensor data, together with environmental context information, to contribute to a paradigm shift in individualized comprehensive understanding of physical and mental health: Toward intelligent assessment and treatment of physical and mental states and risk factors. Current focus is on instrumentation for diffuse optics and biopotentials (fNIRS, DOT, EEG, ExG) and using machine learning for multimodal biomarker discovery, novel approaches in modelling physiology, latent component analysis, and identification of physiological transfer functions.

The IBS lab develops instrumentation and machine learning methods for unobtrusive sensing of signals from the brain and in the body, and extraction of relevant biomarkers. We try to assess mental states (e.g., stress or fatigue) but also physiological health and risk-factors. Greatly simplified: We are working towards a smartwatch for the brain.
