Nanoparticles in the environment

I study the environmental fate and toxicity of nanomaterials. Specifically, I examine the chemistry of silver and titanium dioxide nanomaterials in surface waters and their toxicity to bacteria under dark and solar irradiated conditions. I am part of the Gray Research Group and Gaillard Research Group in Environmental Engineering at Northwestern University.

Some of my recent results were published in a paper in Environmental Science & Technology: http://pubs.acs.org/doi/abs/10.1021/acs.est.6b02271.
