After studying molecular biology and neurochemistry as an undergraduate, he turned to research in artificial life and artificial intelligence. His research explores the collective behavior of social organisms such as honeybees, and the emergence of internal representation and subjective time in artificial systems. In parallel, he creates works with sound as his primary medium, circling around themes such as "distance" and "resignation." He also provides music and sound for fashion shows, theater, retail spaces, and installations.
