The research in our group lies at the broad interface between nanomaterials science and biotechnology. This rapidly advancing research area is commonly termed as nano-biotechnology. Our research includes the basic study of structure-property relationships of nanomaterials and application of this knowledge in the development of innovative materials and functional materials systems.

We are interested in nanostructured materials such as porous Silicon and their interface with soft matter e.g. hydrogels, biomolecules, and living cells. Understanding these interfaces allows us to rationally design biosensors for detection of biological and chemical toxins, new drug delivery platforms, and functional responsive materials.
