The coming layoffs will inevitably affect the quality of our teaching, and we deeply regret the impact this will have on our students. The Study Board for Biological Sciences has articulated their concerns clearly in this opinion piece from UNIavisen. uniavisen.dk/en/the-stude...

The students are also affected by layoffs at the Faculty of Science
We fear cancelled courses and poorer quality of education, and we don't think the management acknowledges the gravity of the situation.
