Personal

I investigate how cognitive processes change with age. In the Schuck Lab, I conducted an EEG study examining how older adults learn from feedback and adapt their choices. Additionally, I supported an fMRI project on how memory changes across the lifespan. These projects have sparked my broader interest in the mechanisms that support adaptive cognition in aging. Besides research, I enjoy practicing mindfulness and attempting to master the German language.
