My research interests include digital signal processing for audio and communications. Recently, my group is working on applying signal processing techniques for Philippine indigenous music, in collaboration with the UP Center for Ethnomusicology. Our group is also interested in applying machine learning techniques and pattern recognition for multimedia applications.
