Dr. Roerdink began his liberal arts career as an undergraduate at Central College in Pella, Iowa. After graduation, Dr. Roerdink spent two years in the printing ink industry formulating inks for flexible packaging. Upon entering graduate school at the University of Wisconsin-Milwaukee, Dr. Roerdink focused on novel methods for detecting arsenic compounds in environmental matrices by chromatography and mass spectrometry. Arsenic compounds are added to various animal feeds as an antibiotic. When the animals' waste is used as a fertilizer, arsenic is introduced to various soils and streams.

Dr. Roerdink arrived at Heidelberg in June of 2006 where he holds a dual appointment between the Chemistry Department and the National Center for Water Quality Research. Currently, Dr Roerdink is developing a method for the routine determination of glyphosate, a pesticide widely used in regions where glyphosate-resistant crops are grown.
Dr. Roerdink enjoys spending time with his family, running, playing volleyball and watching the Packers. He also enjoys watching the Olympics and studying the analytical methods used to determine if athletes are using performance enhancing drugs.
