The Helmholtz Centre for Environmental Research

Leipzig, DE

The Helmholtz Centre for Environmental Research – UFZ, Germany, was established in 1991 as the first and only Centre within the Helmholtz Association of National Research Centres to be exclusively devoted to environmental research in a great variety of fields. It employs around 1,100 people in Leipzig, Halle and Magdeburg, Germany. Founded in response to the severe pollution prevailing in Central Germany, the UFZ has become a world-wide acknowledged Centre of expertise in the remediation and renaturation of contaminated landscapes, as well as the preservation of biodiversity and natural landscapes and still is one of the world’s leading research institutions in environmental research. The overall goal of the UFZ is to demonstrate ways to combine societal development with a healthy environment while facing challenges such as climate change or exposure to chemicals and pollutants by conducting excellent research and taking a shaping role in the scientific community. To fulfil this goal, UFZ unites expertise of natural and life sciences, engineering and social sciences forming an interdisciplinary network of close collaboration.

Special focus within the UFZ research unit “Chemicals in the environment” is to increase the understanding of the fate of chemicals after they have been released into the environment and to understand how man-made chemicals impact human health and wellbeing. Increasing knowledge in this field will lead to a better risk assessment.

Besides producing, collecting and analysing research data, the UFZ supports the political arena and the economic as well as the general public to increase the understanding of consequences that human actions may have on the environment. In this context, options for social and political decision-making processes are developed, always following the precautionary principle.

Role in the project

Prof. Ana C. Zenclussen from UFZ is the leading PI and coordinator of ENDOMIX. UFZ is in charge of four out of nine work packages, including the project coordination, management and clustering activities. The ENDOMIX kick-off meeting is organized by Ana Zenclussen and will take place at the UFZ in Leipzig, Germany, on January 30th/31st as a hybrid event. All projects funded under this call will form the joint cluster ENKORE to optimize collaboration among all projects and increase the scientific output. Within ENKORE, Ana Zenclussen, on behalf of the UFZ, is the coordinator of the first period (2024/2025).


Ana C. Zenclussen

Prof. Ana C. Zenclussen is an expert in feto-maternal immune communication.

Before joining the UFZ, she was a Postdoctoral Researcher at Otto-von-Guericke University (OVGU) Magdeburg. There she worked on projects investigating the influence of environmental estrogens on the immune response during pregnancy. Dr. Meyer earned her Ph.D. from OVGU Magdeburg, focusing on the involvement of uterine mast cells and natural killer cells in successful pregnancies. She pursued her Diploma in Biology at the Technical University of Dresden.

Tobias Polte

PD Dr. Tobias Polte leads a research group in the Department of Environmental Immunology that studies the influence of maternal exposures on disease development in the offspring. After completing his doctorate in pharmacology at the Martin Luther University in Halle/Saale, he worked as a scholarship holder of the German Research Foundation at the University of Bath (UK) and the Stanford Medical School. He then returned as a postdoc at the children’s clinic at the University Medical Center in Halle/Saale and later recruited a junior research group for the Helmholtz Centre for Environmental Research – UFZ and the University of Leipzig. He served as deputy and acting department head in the Department of Environmental Immunology. His current research focus is on the role of environmental pollutants such as EDCs as risk factors in the development of immune diseases like allergic asthma but also possible effects on metabolism or behaviour across generations using various mouse disease models.

Violeta Stojanovska
