We are looking for a scientist as part of the establishment of a new health center to investigate the influence of environmental and climate factors on children's health. We look forward to your applications!

The GIT laboratory journal by Wiley Analytical Science recently published an interview with Prof. Ana Zenclussen regarding the dangers of environmental chemicals. It highlighted our ENDOMIX project, which investigates the effects of endocrine disrupting chemicals (EDCs). Click here for the full interview.

You can now follow exciting news about project progress, publications, and upcoming events on the official ENDOMIX website. We look forward to your visit!

Last week, Ana Zenclussen and two of our medical PhD students attended the annual meeting of the Society for Reproductive Investigation (SRI) in Vancouver, Canada, and presented their recent research.

We warmly welcome our new project coordinator Thi Anh Mai Pham as well as our new PhD students Julia Canning Clode Castro-Neves and Verena Mailänder to the team!

The kick-off meeting for our EU-funded project ENDOMIX took place 30th/31st January in the Kubus. We look back on two amazing, motivating days full of productive discussions and a lot of commitment and look forward to working on it together!

On January 18th, the 17th Research Festival for Life Sciences took place at the University of Leipzig. Dr. Tobias Kretschmer presented a poster about his research on endocrine-disrupting chemicals and their effects on fertility.

We are happy to announce that our new research project ENDOMIX, initiated and coordinated by Prof. Ana Zenclussen, has officially started on 1st January 2024. Within the project, we aim to investigate the previously hidden dangers of endocrine disrupting chemicals (EDCs) and to decipher their effects on human health.

Read the official press release here.

On November 29th 2023, the international workshop "Environment, climate change and health", organized by Chiba University, Japan, the University of Leipzig and the Charité Berlin, took place in Leipzig. Also UFZ scientists presented their research and there was the opportunity for exciting discussions.
