Research Interests
My research group is mainly focused on Ultra High Vacuum (UHV) Scanning Tunneling Microscopy (STM). With this microscope, we study adsorbates bonded to surfaces as well as the controlled manipulation of atoms and molecules on surfaces.
In the past my reserach activities have included STM studies of semiconductor heterostructures as well as soft X-Ray absorption and fluorescence from novel semiconductor materials.
Recently I have been actively involved in using cantilevers such as used in Atomic Force Microscopy (AFM) to test Newtonian dynamics at very low levels of acceleration i.e. near 1e-10 m/s^2.
