I am member of the SPP 2026 „Geometry at infinity“, see SPP2026.

Since 2022, I am member of the AK-Gleichstellung. We try to improve the working environment toward an open culture.

I am co-founder of the initiative Meet&Math.

I give talks trying to convince school students that mathematics is interesting.
