Detlev Helmig, principal investigator

Institute of Arctic and Alpine Research, University of Colorado-Boulder

Detlev is the primary investigator on this project.  He has done field studies, including measurements of biosphere-atmosphere trace gas fluxes and their environmental controls, all over the world, including projects in Antarctica, the Azores, Greenland, and across the world’s oceans. (See more about the Ozone and the Oceans project.) The picture shows Detlev getting ready to climb a research tower at the University of Michigan Biological Research Station.

Romain Baghi, student intern

Institute of Arctic and Alpine Research, University of Colorado-Boulder

Romain is visiting from Toulouse, France. He is focusing on VOC emissions from trees in their flowering stage. After his six-month internship here, he will receive his master's degree in atmospheric sciences from Paul Sabatier University.

Tanarit Sakulyanontvittaya, graduate student

Institute of Arctic and Alpine Research, University of Colorado-Boulder

Tanarit is also studying Mechanical Engineering, working toward his Ph.D. Tanarit is using the emissions data for models of the atmosphere that are then used to predict the emissions of sesquiterpenes from different urban and forested areas throughout the year.

Alex Guenther, co-investigator

National Center for Atmospheric Research (NCAR), Boulder, Colorado

Alex is a senior scientist and section head at the National Center for Atmospheric Research in Boulder.  He has studied VOC emissions from plants for more than 20 years on five continents. He has also developed models to estimate these emissions around the world that are used by many other scientists and air quality regulators. In this picture, the Teflon bag in front of Alex encloses a small arm of a saguaro cactus. Despite the extra-thick bag, the cactus managed to punch it (and Alex) full of holes.

Ryan Daly, graduate student

Institute of Arctic and Alpine Research, University of Colorado-Boulder

Ryan's graduate research project was studying emissions of sesquiterpenes in greenhouse experiments and at field sites, including our local study area at the Creekside Tree Nursery in Boulder. After earning his MS degree in Mechanical Engineering in 2010, Ryan began a new job at the EPA, where he continues to research biogenic emissions.

Eva Joó, visiting graduate student

Research Group EnVOC, Department of Sustainable Organic Chemistry and Technology, Ghent University, Belgium

Eva is in Boulder for four months to study the reactivity of biogenic emissions. A chemical engineer with a focus on organic chemistry, she is running experiments on the reactivity of ozone.
