The EnviroNano group, along with friends, family, nano-dogs and visitors at Carol's farewell party.

We are the Environmental Nanoscience group at Virginia Tech, led by professors Michael Hochella Jr (University Distiguished Professor, Geosciences), Mitsu Murayama (Materials Science & Engineering), and Marc Michel (Geosciences).

Our research, in a broad sense, aims to understand complex, environmentally relevant interactions between minerals, microbes, and metal contaminants. To this end our studies include laboratory experiments, mesocosm experiments, and field work, analyzed all the way down to the nanoscale.
