I have 15 years of experience, and specialize in the field of nanoelectronics with specific knowledge in the areas of semiconductor heterostructures, carbon nanomaterials and novel device concepts. I have published on such topics as graphene devices, carbon nanotubes and single electron transistors. I lead a center focused on developing new types of probes of electronic, optical, magnetic, and mechanical properties of materials and devices on the 1-100 nanometer scale.
