Signal processing algorithm design for biomedical sensor arrays

Alexander Bertrand's research involves signal processing algorithm design with a focus on biomedical sensor arrays, such as electroencephalography (EEG), neural implants, ultrasound probes, and distributed body- and neuro-sensor networks. Applications include brain-computer interfaces, cognitive control of hearing prostheses, and wearable neuro-monitoring with 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, beamforming, adaptive filtering, and signal enhancement.
