Biography

Novel nanomaterials are developing at a rapid pace as they offer new possibilities for applications in electronics, optics, nano-mechanics and medicine. We study the synthesis and modification of especially carbon-based nanostructures, often using graphene as the starting point. New fabrication techniques are developed using cleanroom techniques as well as femtosecond laser processing, and the resulting nanostructures are incorporated in device geometries that benefit from having nanometer precision in critical features. Applications range from low temperature electronic transport in 2.5 dimensional structures, area-selective ALD deposition, microfluidic sorting of nano- and micrometer objects, to in-vivo neural sensors of graphene. Our projects are often interdisciplinary in nature, with groups from biology, chemistry and physics working together.
