Jérôme did his bachelor's degree in water engineering at Université Laval. He realized a summer internship with the modelEAU team, where he worked on BOD characterization, and more specifically on its repeatability with the Oxitop method. In order to improve the quality of the laboratory sessions of the "Dispersion des polluants" class and in order to know more about the Oxitop equipment, laboratory experiments have been conducted during the Summer of 2009.
