研究领域

Our research group develops new variations of scanning probe microscopy. In particular, we are working on nanoscale infrared imaging tools with sub 10 nm spatial resolutions. With these tools that we have developed, we study the composition, organization, and interactions of molecules, material, and nanostructures.
