Synthetic biological materials: from artificial cell membranes to biomimetic minerals and living materials.
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.

Living materials and biomineralized composites
We use microorganisms to fabricate bio-based and/or living materials. Most living organisms use elements in their environment to fabricate composite materials. Due to their intricate and hierarchical structure, biocomposite materials present improved material properties when compared with their pure inorganic counterparts. Collaborations: Anne Meyer (University of Rochester, USA), An-Wu Xu (USTC, China), S. Garcia (TU Delft), Filipe Natalio (Weizmann Institute, Israel).
