Research Interests

Investigation of fundamental physical and chemical properties at the single-molecule level. Development of novel instrumentation capable of addressing and manipulating individual molecules at ever increasing resolution and reliability. Scanning Tunneling Microscopy is the key instrument of my lab; other instrumentation includes Transmission Electron Microscopy, Femtosecond Laser Excitation and Thermally Programmed Desorption.
