Research in biomedical signal processing is pursued in the areas of electrocardiology, dialysis, eye-tracking, and neuroengineering. The projects involves aspects such as modeling, simulation, processing and interpretation to better understand properties of physiological systems. Special emphasis is put on addressing issues related to atrial fibrillation, where Center for Integrative Electrocardiology (CIEL) plays a key role in the collaboration between cardiologists and engineers.
