The core of the research work of the team of Dr. Nederkoorn is patient oriented studies in stroke, focusing on clinical burning questions in stroke that can be answered with pragmatic, investigator driven studies. An example is the recently finished Preventive Antibiotics in Stroke Study (PASS), a study that we designed after seeing so many post-stroke infections worsening our patients in real life. Dr. Nederkoorn is also doing research and is clinical expert in carotid artery disease.
