The objective of my research is to improve our understanding of the relationship between the surface properties of a biomaterial and the biological reactions occurring on that material.
Biomedical Surface Analysis
Surface & Interface Characterization
Surface Modification
Our research is focused on determining in detail the surface structure and composition of a material, as well as the interaction of biomolecules with the surface of materials. Surface analysis methods used include x-ray photoelectron spectroscopy, static time-of-flight secondary ion mass spectrometry, scanning force microscopy, near edge x-ray adsorption spectroscopy, sum frequency generation and surface plasmon resonance. Current research projects include the characterization of model biomaterial systems (self-assembled monolayers, peptides, ordered proteins, biosensors, DNA microarrays, etc.), the development of 2D and 3D chemical state imaging methods for analysis of organic and biological samples, and characterization of surface immobilized biomolecules.
