  • Demetrios Braddock

    Associate Professor of Pathology

    Demetrios Braddock was born in Tennessee, educated at the University of Chicago, trained at the NIH in Anatomic Pathology and Biophysical Chemistry, and came to Yale in 2004. He practices Hematopathology and leads a laboratory that studies the ENPP enzymes – a family of extracellular enzymes that create small molecules in the extracellular environment that regulate organismal homeostasis in processes such as hemostasis, bone mineralization, and vascular development. We are especially interested in a rare disease of lethal vascular calcifications called 'Generalized Arterial Calcification of Infancy' (GACI) associated with ENPP1 deficiency, and designed and validated an enzyme therapy that was curative in a mouse model of GACI. We are now moving this therapy into patients in collaboration with a company we founded (Inozyme Pharma). We have also identified a form of early onset osteoporosis associated with ENPP1 deficiency, and are investigating the role of ENPP1 in low bone mass and increased tissue calcification, a medical condition called 'Paradoxical Mineralization' which occurs in the general medical population in conditions such as aging and chronic kidney disease.

  • Shawn Cowper

    Professor of Dermatology

    As a dermatopathologist, I interpret biopsy specimens sent to our laboratory from dermatologists and surgical specialty providers. While I do not interact with patients directly, I provide pathology consultative services on thousands of individual patients each year. In addition, as a dermatopathologist with a specialty interest in hair loss, I am among a small number experts who regularly teach and lecture on the topic of the biopsy interpretation of hair loss (alopecia). I regularly receive biopsy specimens for interpretation from consultants around the country.

After graduating from Yale, Karin completed residency training in Clinical Pathology at Massachusetts General Hospital and clinical fellowship training in the Harvard Medical School Molecular Genetic Pathology Training Program based at Brigham and Women’s Hospital. She then completed postdoctoral research training in the laboratory of Dr. Nancy Andrews, first at Children’s Hospital Boston and later at Duke University Medical Center, where she employed genetic study of patients with an inherited form of iron deficiency anemia to shed insight into mechanisms of systemic iron regulation. In her research laboratory at Yale, Karin continues to investigate mechanisms of iron balance through genetic study of patients with iron-related phenotypes and through characterization of genetically targeted mouse models. She also contributes to patient care as a molecular genetic pathologist in the Molecular Diagnostics Unit of the Department of Pathology.
