Positions Open for Graduate Students

Our research centers on the development of novel multi-metal nanostructures and new methods for functionalizing their surface with soft and hard materials, with an ultimate goal to establish the structure-property relationship and further explore their applications in energy conversion, tribology, and nanomedicine.
