Research Interests

Dr. Johnson's research focuses on chemical thermodynamics and kinetics of reactions at the interface between liquids and solid-surfaces using the imaging techniques of scanning tunneling microscopy (STM) and atomic force microscopy (AFM), and the spectroscopic techniques of infrared reflection-absorption spectroscopy (IRRAS) and surface enhanced Raman scattering spectroscopy (SERS). Studies of self-assembled monolayers with acid/base functionality and their interaction with aqueous solutions are ongoing.

In August 2001, Dr. Johnson, with Dr. Whiteley and Dr. Parr, received a Major Research Instrumentation Grant from the National Science Foundation for $107,000. This grant purchased a new STM/AFM instrument for undergraduate research in the chemistry department at Pacific.

In 2001-'02 Dr. Johnson spent a 10 month sabbatical at the Chemistry Department of the University of Arizona as a visiting scientist in the laboratory of Dr. Jeanne E. Pemberton. The Pemberton group uses electrochemical and spectroscopic methods to investigate chemistry at interfaces. While at the University of Arizona, Dr. Johnson designed a sample cell and optical system to implement a novel spectroscopic technique, Emersion IRRAS. When he returned home from his sabbatical, Dr. Johnson brought with him a second version of the Emersion IRRAS cell for use at Pacific with undergraduate research students. In addition, Dr. Johnson maintains a collaboration with Dr. Pemberton, and each summer a Pacific undergraduate chemistry major has the opportunity to spend a summer in at the University of Arizona in Tucson in a Research Experience for Undergraduate (REU) position sponsored by Dr. Pembertion's NSF grant.
