UMW NEWS BUREAU Former Montana Western student Levi Mielke will be the next featured guest at the On the Rocks speaker series on Monday, March 28. Mielke’s presentation, “Change is in the air: Biosphere-atmosphere interactions in an industrial world,” will begin at 4 p.m. in Block Hall Room 311 on the UMW campus. Mielke, who attended Montana Western as a student in the environmental sciences department, will be presenting on the tropospheric ozone and aerosol production from the oxidation of volatile organic compounds. After studying at Montana Western Mielke earned a B.A. in chemistry from Carroll College and then a Ph.D. in analytical chemistry from Purdue University. While at Purdue, Mielke developed a mass spectrometric technique to quantify biogenic emissions and their reaction products in real time. He is currently a postdoctoral researcher at the University of Calgary, where he is focusing on developing mass spectrometry techniques for quantifying ozone precursors in real time.
 Tropospheric ozone and aerosol particulate matter are regulated by the Environmental Protection Agency due to their affect on human, animal, and plant health. Fully understanding the production mechanisms for ozone and its precursors informs policy makers in considering and developing responsible regulatory decisions. Mielke’s presentation will focus on why volatile organic compounds are emitted by vegetation and how they react to form ozone and aerosol particles in the atmosphere. On the Rocks presentations are always free and open to the public.
