As a materials scientist specialized in surface analysis using time-of-flight secondary ion mass spectrometry (ToF-SIMS) and scanning probe microscopy (SPM), I provide consultancy in areas related to surface/interface chemistry and metrology to industrial clients. My research interest focuses on developing (a) analytical approaches to exploring surface chemistry and chemical structures and (b) new methodologies to understand formation mechanisms of self-assembled monolayers of organophosphonic acids and organosilanes, as well as their applications in surface engineering.
