1. Living materials and biomineralized composites
Living organisms are using elements in their environment to fabricate materials with impressive mechanical/optical/electrical properties, together with sensing and responsive functions. For example, mollusc nacre shows excellent mechanical toughness due to its layered brick-and-mortar structure. Inspired by this, we use microorganisms to fabricate biomimetic composite materials combining high stiffness and toughness, following a sustainable approach. We also make light responsive engineered living materials composed of microalgae.

2. Mechanical processes at the cell membrane
We design, develop and use biophysical assays to track dynamical cellular processes occurring at the cell membrane. We study artificial cell membranes as well as living (algal and bacterial) cells. Our interest is in the study of individual biomolecules, cells and membranes under external physical/chemical stimuli. This, in the hope of understanding the molecular mechanisms driving biological processes.
