Research Interests

I am interested in using AFM and in situ TEM testing to explore the adhesion, friction, and wear at the nanoscale.  Particular research efforts include:

  1. Performing wear tests with in situ TEM imaging to uncover fundamental principles of nanoscale wear.
  2. Performing indentation and adhesion studies inside the TEM to try explore the limits of applicability of continuum contact mechanics at the nanoscale.
