I am a postdoctoral in the group of Prof. Salmeron, in the Materials Sciences Division of the Lawrence Berkeley National Laboratory.
My research focuses on studying the interaction of water with different surfaces, including mica, KBr, and TiO2. I want to find out how water solvates and dissolves ions when it forms nanometer thin films on surfaces. I investigate ionic mobility, and ion distribution in the liquid film and their possible segregation to the film-substrate interface and to liquid film-air interface. In this project I use Scanning Polarization Force Microscopy, SPFM, an electrostatic force operation mode of the Atomic Force Microscope (AFM). Another very useful technique is Ambient Pressure Photoelectron Spectroscopy (APPES), which allows me to record XPS spectra of surfaces in ambient pressures of any gas up to a few Torr.

Another project I work on is the study of the friction and wear properties of Cu, for applications in electrical motor rotor and brushes. For these studies I use environment-controlled AFM and electrochemical AFM to understand the friction behavior of metal surfaces under variable conditions, such as high humidity and oxidation.
