Research

I am interested in how physical models of stuff (models such as partial differential equations) make traditional signal processing problems more tractable. This led me to a study of inverse problems in room acoustics, and to eventual realization that the most robust and useful approach to these problems is through the constructive use of echoes. Using echoes through geometric insights is in contrast to heavyweight full-wave approaches. It also goes against the usual wisdom that reverberation is bad, by making it work for us.

Previously I did some research on signal processing on n-dimensional spheres with Davor Petrinović at the Department of Electronic Systems and Information Processing (ZESOI), Faculty of Electrical Engineering and Computing (FER), University of Zagreb. Before that I worked with Sanja Tomić from Ruđer Bošković Institute and with Mile Šikić from ZESOI on problems in structural proteomics (more generally in bioinformatics).

Teaching

I am a teaching assistant for the lab’s master course, Mathematical Signal Processing. While at FER, I was a TA for the following courses,
