Haley Cropper

Graduate Student

Neurology and Rehabilitation


Haley Cropper is a graduate student in the Medical Scientist Training Program at UIC-COM. Before starting medical school, she received her Bachelor of Science in Biopsychology Cognition Neuroscience at the University of Michigan, and spent 2 years doing neuro-radiology research at Stanford University. There, she developed novel positron emission tomography (PET) tracers to study neuroinflammation in chronic pain, Multiple Sclerosis, and Alzheimer’s Disease. She is now studying neuroimmune interactions in preclinical models of migraine and depression in the Pradhan Lab.


Advisor: Dr. Jeffrey Loeb
