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.


  • Carol Johnson defended her Ph.D. with success! She will now start a new stage of her life with a Postdoc at Duke University! Congratulations Carol, Geosciences wishes you all the best!
  • Mitsu Murayama's great research performance was once again recognized, with The 2014 Deans's Award for Faculty Fellow. Congratulations Mitsu!
  • Another great achievement of Hannah King, awarded with the Society of Exploration Grophysics/ExxonMobil Student Education travel grant to Denver!
  • Marc Michel was featured in the article "Virginia Tech researchers search for ways to better trace effects of coal ash spills" in The Roanoke Times for his contribution in the development of new approaches to better trace long-term effects of coal ash spills.
  • James Dale passed his prelims with success and is now a Ph.D. candidate. Congratualtions James!
  • Carol Johnson was awarded with the Geosciences Outstanding Graduate Service Award, during her graduation graduation ceremony and plans to defend her thesis in August. Let's go Carol! 

  • CEINT researchers, including Michael Hochella were featured with in a New York Times article entitled "Silver too small to see, but everywhere you look"
