Mark Tobler
Mark Tobler

Mark Tobler joined the Department of Biological Sciences in 2008. He currently works with Dr. Paul Barnes examining plant and ecosystem responses to global climate change. Additional research areas include plant-insect interactions, chemical ecology of plants, and plant population dynamics in wetland ecosystems. He also serves as the greenhouse coordinator for the Azby Greenhouse Facility.



M.S. in Biology (plant-animal interactions) University of Louisiana-Lafayette 2000; B.S. in Biology (plant ecology) from University of Montana 1997
