Research:

Research in my group involves the development of analytical techniques for the characterization of nanomaterials and their dynamic transformations in biological and environmental matrices. Specifically, we are developing a suite of in situ electrochemical, spectroscopic, and separation technologies to monitor and quantify silver nanoparticle (AgNP) dissolution, aggregation, and protein corona formation. We are also applying these techniques to understand how AgNPs that are incorporated into consumer products (e.g., clothing fabrics) may be released during use of the product (e.g., wearing or washing the clothing).
