Current position: Graduate Student at the University of Colorado Boulder

My project was focused on investigating the reactive loss of ozone to freshwater surfaces including Lake Mendota to determine the significance of these surfaces as an ozone sink in the atmosphere. I have been working to develop an experiment set-up with a flow tube to measure ozone loss to sample solutions using a Personal Ozone Monitor. A manuscript has been submitted to ACS Air for this project.
