Professor Urs von Gunten stands as a preeminent figure in environmental chemistry with transformative contributions to global water safety standards. Born in Baden, Switzerland on October 20, 1959, he earned his diploma in chemistry from ETH Zurich in 1983 followed by a PhD in inorganic chemistry from the same institution in 1989. His distinguished career began with post-doctoral research at the Swiss Federal Institute of Aquatic Science and Technology (Eawag), where he steadily ascended to leadership positions including head of the chemistry department from 1998 to 1999 and head of the Water Resources and Drinking Water department from 2000 to 2004. Currently serving as Professor Emeritus at École Polytechnique Fédérale de Lausanne (EPFL) while continuing to lead the drinking water chemistry group at Eawag, he exemplifies enduring commitment to advancing water science despite formal retirement.
Professor von Gunten's groundbreaking research has fundamentally transformed our understanding of chemical processes in drinking water treatment, particularly regarding oxidation and disinfection mechanisms. His extensive studies on the formation of potentially toxic byproducts during ozonation and chlorination have provided critical insights that have directly influenced international water safety standards and treatment protocols worldwide. His innovative work on the kinetics and mechanisms of disinfection byproduct formation has enabled water treatment facilities to optimize processes while minimizing health risks to consumers through rigorous scientific frameworks. Through leadership of the cross-disciplinary project 'Drinking Water for the 21st century' and the competence center for drinking water (2010-2017), he established comprehensive approaches balancing pathogen elimination with chemical byproduct reduction.
Beyond his direct research contributions, Professor von Gunten has profoundly shaped the field through mentorship of numerous doctoral students whose dissertations on oxidation processes and micropollutant degradation now guide contemporary water treatment practices. His role in transdisciplinary projects including 'Regional Water Supply Basel Country 21' cemented his position as a central figure in Swiss and European water policy discussions. Despite transitioning to emeritus status, he continues to guide the laboratory for Water Quality and Treatment at EPFL, ensuring the next generation carries forward his rigorous scientific methodology. His current research addresses emerging contaminants and advanced oxidation processes that will shape sustainable water treatment solutions amid increasing environmental pressures and evolving water quality challenges.
