Research Project

Quantifying surface reaction kinetics with SECM

Scanning electrochemical microscopy (SECM) is a technique where a small electrode is moved over a surface. The current at the electrode can be used to create an 'image' of the surface from which we can infer relative rates of reactions occurring at the surface. My project involves using finite element method simulations and fitting algorithms to quantify the kinetics of these reactions from the SECM image.
