The background shows a bright modern room with white walls and wooden flooring. In the upper left, a colorful speech bubble contains the text: “I am an image analyst. I help biologists and chemists to analyze their image data and get information and quantification out of microscopy images, thus allowing them to modify or plan experiments.” The Leibniz-HKI logo appears in blue at the bottom left, and an orange arrow points to the right. Colorful calendar page for October 2025 from the Leibniz-HKI Calendar. The background fades from blue on the left to purple on the right. The word 'OCTOBER' appears in bold orange letters.

A young woman with glasses sits on a wooden bench outdoors, smiling at the camera while holding a viola on her lap. She is wearing a black top, wide green pants, and black heeled sandals. On the left side of the image, there is a large colorful speech bubble with the following quote: “I primarily focused on the symbiosis between fungi and endosymbiotic bacteria. We identified natural products produced by the bacteria that protect the fungi from predators and play a key role in the symbiotic relationship.” At the bottom left, the “Leibniz-HKI” logo is visible. At the bottom right, a large purple arrow points to the right. A graphic calendar page with a turquoise-blue gradient background. In large pink letters it says “SEPTEMBER,” and underneath: “Hannah Büttner.” At the lower left is the “Leibniz-HKI” logo with the text “Leibniz-HKI Calendar 2025.” At the lower right, the word “SWIPE” is written in bold black letters next to a large purple arrow pointing to the right. A young woman in a white lab coat is working in a laboratory. She is holding a pipette and placing a sample into a scientific instrument. On the right side of the image, there is a speech bubble in a turquoise color gradient with the text: “I particularly enjoyed structural elucidation and analytical challenges.” Below, the logo of LEIBNIZ-HKI is visible. A large purple arrow points to the right. A young woman with glasses, wearing a black t-shirt and green trousers, stands indoors next to a large aquarium full of fish and aquatic plants. She holds a viola under her arm and looks thoughtfully into the distance. Her reflection is visible in the aquarium glass.
