Wilfried Winiwarter

Senior Research Scholar

Pollution Management Research Group

Energy, Climate, and Environment


Wilfried Winiwarter is a senior research scholar in the Pollution Management Research Group of the IIASA Energy, Climate, and Environment Program. He originally trained as a chemical engineer and worked as an atmospheric scientist before joining IIASA in 2003. His interest in systems analysis derives from the overarching challenges of climate research. He acquired expertise in the biogeochemical cycle of nitrogen, especially on its anthropogenic impacts. This includes describing methods to minimize the release of ammonia or nitrous oxide into the environment, which are often connected with agricultural activities.

Winiwarter started his academic career at the Vienna University of Technology, where he obtained a PhD degree and a postdoctoral qualification for academic teaching ('Habilitation'). Partly in parallel with his IIASA affiliation, he was a senior scientist at the Austrian Institute of Technology (AIT), and also held a two-year term as Professor for Systems Sciences at the University of Graz. Since October 2017, he has been working as Professor of Environmental Chemistry at the Institute of Environmental Engineering, University of Zielona Gora, Poland. In 2019, he received an International Fellowship of the President of the Chinese Academy of Sciences (PIFI) that was extended in 2021. This allowed him to spend several weeks in 2019 working with experts from the Center for Agricultural Resources Research of the Chinese Academy of Sciences (CAS) in Shijiazhuang, China, and to continue this collaboration remotely during the COVID-19 pandemic.

Having served as a Director of the European Centre of the International Nitrogen Initiative (2013-2016) and as a deputy chairman to the Climate and Air Quality Commission of the Austrian Academy of Sciences (until 2023), Winiwarter currently chairs the scientific advisory board to the Institut fur Agrartechnik und Biookonomie (ATB) in Potsdam, Germany - an institute of the Leibniz Association.
