General Description
The Biomedical Signal Processing Group is in collaboration with the Institute of Biomedical Engineering, Bogazici University. Main research activities branch into two fields: functional near infrared spectroscopy (fNIRS) and lung acoustics.

Description
Functional
near infrared spectroscopy (fNIRS) is an emerging
non-invasive brain monitoring modality, with certain superiorities vis-à-vis
other modalities, such as positron emission tomography (PET) and functional
magnetic resonance imaging (fMRI). The research
objectives of fNIRS Group are as follows:
