I am a clinical fellow in internal medicine and psychosomatic medicine. I am interested in modern assessment methods in pain, personality structure, and other constructs. That includes instruments based on item-response theory, computer adaptive testing, and ecological momentary assessment. Using these techniques I am currently seeking to improve the measurement of pain states and identification of phenotypes in pain.

Since 2022, I am Fellow of the BIH Charité Digital Clinician Scientist Program!
