Research Overview

We use DNA nanotechnology to construct simplified models of complex biological systems, where single structural and functional parameters can be manipulated in a predictable fashion. Our scientific ambition is to gain a better understanding of three fundamental aspects of natural self-assembling systems: hierarchical order, spatial confinement, and dynamic response.
