Alexander Bertrand is Professor at the Electrical Engineering Department (ESAT) of KU Leuven, Belgium. He received the Ph.D. degree in Engineering Sciences (Electrical Engineering) from KU Leuven, in 2011. His research involves signal processing algorithm design with a focus on biomedical sensor arrays, such as electroencephalography (EEG), neural implants, ultrasound probes, and body-sensor networks. Applications include brain-computer interfaces, auditory and visual attention decoding, cognitive control of hearing prostheses, and distributed neuro-sensor networks. He also conducts research in generic signal processing techniques, with a focus on multi-channel and distributed signal processing, spatial filtering, and signal enhancement.
