I am one the developers for the WFDB Toolbox for MATLAB and Octave. This toolbox gives users direct access to over 50 databases (over 3 TB of physiologic signals including ECG, EEG, EMG, fetal ECG, PLETH, ABP, and more). Most of these databases are also accompanied by meta-data such as expert annotations of physiologically relevant events. These can include, for example, cardiologist annotations on ECGs for classifying different arrythmias, or sleep expert annoations on EEG for segmenting different sleep stages. The project is open-source and web page is located at: http://physionet.org/physiotools/matlab/wfdb-app-matlab/
Professional Interests: Statistical & Adaptive Signal Processing, Biosignal Processing, Detection & Estimation, Analysis of Evoked Responses, Pattern Classification
