Research Interests

I am interested in the fundamentals of nanomaterial behavior in the environment, ranging from interactions with biomolecules or pullutants to attachment to microorganisms and environmental surfaces, and their effects on nanoparticle transport. My approach blends experimental studies, mathematical modeling, and computational simulations.

Increase in alpha results in increase in trophic transferThe binding of select pesticides to nanomaterials from molecular dynamic simulations
