Dr. Westerhoff has garnered wide recognition for his work related to treatment and occurrence of emerging contaminants in water, and has been active in multidisciplinary research. He has lead funded research investigating reactions and fate of oxo-anions during water treatment, characterization, treatment and oxidation of natural organic matter in watersheds, formation of disinfection by-products, removal of taste and odor micropollutants and fate of nanomaterials in water. He has over 68 peer reviewed journal article publications and has been involved in over 200 conference presentations. He belongs to several professional societies and serves on numerous voluntary committees for them.
