Hierarchically structured (photo)catalysts, such as zeolites or cucurbit[n]urils include a desired distribution of active sites, and a network of broad pores that allow more facile access of the active sites and mitigate catalyst deactivation, as well as control surface barriers. Inspiration is sought from leaves, tissues, even skin, to develop more efficient (photo)catalysts for sustainable chemical and fuel production

We create artificial membranes for separation processes, which implement fundamental principles of biological membranes, to combat fouling, and improve/tune selectivity and permeation rate. Examples of our work in this area include nanomaterial-enhanced membranes (e.g., with cucurbit[n]urils or nanoparticles) for high-performance gas separation, proton exchange, and dye removal; or membranes for water desalination, purification and bio-separations.

We develop new nature-inspired structural proteins that fuse in a single biopolymer chain the properties of dissimilar structural properties in nature, such as silk, elastin, or resilin. These proteins can be used for the manufacture of materials with applications in soft robotics, biomedical materials, or biosensing. Additionally, we leverage the synergistic interaction between cells and biopolymeric scaffolds in animate matter to develop materials with life-like properties.
