Andrew Schrepf, PhD

Dr. Schrepf is an Assistant Professor of Anesthesiology at the University of Michigan Chronic Pain and Fatigue Research Center (CPFRC) and an Assistant Professor of Obstetrics & Gynecology at Michigan Medicine. His work focuses on inflammatory biology of complex medical symptoms, post-treatment symptom trajectories in chronic pain, immune system influence on the central nervous system, and Quantitative sensory testing in chronic pain.
Dr. Schrepf works with our team to look at how inflammatory markers might predict response to treatments, as well as the linkage between inflammation, early life adversity, and pain. Dr. Schrepf has a key role in our ongoing study where he looks at how pain mechanisms influence treatment response.
Maria Hadjifrangiskou, PhD, MD & Seth Reasoner


Dr. Maria Hadjifrangiskou is a Senior Assistant Dean of Biomedical Research, Education, and Training (BRET) and a Professor of Pathology, Microbiology and Immunology as well as Urology at Vanderbilt University School of Medicine. Dr. Hadjifrangiskou runs the H Lab at Vanderbilt University, leading a group of experts that are evaluating the urinary microbiome and working to understand how bacteria functions in our bladders. Their work focuses specifically on uropathogenic E. coli.
Seth Reasoner, a former MD/PhD student in the H Lab, is now a Resident Physician at Case Western. Seth works with our team to look at how the urinary microbiome works in IC patients and specifically has helped us to understand how the bacterial composition in the bladder is different in patients with a localized pain phenotype.
