Surface chemistry has been observed to influence many environmental processes such as bacterial adhesion, contaminant adsorption, and biomineralization. Research in our laboratory focuses on investigating how surface modifications modulate the dynamics of nanoparticle formation, stability, mobility, and bioavailability. The overarching goal is to gain a better quantitative and mechanistic understanding of the fate and transport of metal-based nanomaterials in natural and engineered aquatic systems.
Examples of ongoing projects:
Research Area #1: Formation of nanoparticles
Use of surface-sensitive techniques to investigate nucleation in the process of biomineralization
Research Area #2: Stability of nanoparticles
How does nanoscale surface heterogeneity affect nanoparticle aggregation?
Research Area #3: Mobility of nanoparticles
Effects of biofilms on nanoparticle adsorption
Research Area #4: Bioavailability of nanoparticles
Design of in-vitro model systems to assess the factors that govern nanomaterial interactions with physiological surfaces
