Biography Summary

Abbe N. de Vallejo, PhD, is a highly regarded researcher and educator with a funded research program. He is Associate Professor in the Division of Pediatric Rheumatology at Children's Hospital of Pittsburgh of UPMC, and Associate Professor of Pediatrics and Immunology at the University of Pittsburgh School of Medicine. He also holds appointments as Member Faculty of the McGowan Institute for Regenerative Medicine and the University of Pittsburgh Cancer Institute, and is director of the Flow Cytometry I Core Facility at the John G. Rangos Sr. Research Center.

Dr. de Vallejo earned a master's degree in Pathobiology at Stirling University in Scotland, U.K., and a doctoral degree in Microbiology and Immunology at the University of Mississippi Medical Center. He undertook postdoctoral studies at the Mayo Clinic, focusing on the molecular evolutionary genetics of the MHC gene family in primates. Dr. de Vallejo remained at the Mayo Clinic to pursue clinical-oriented training in Rheumatology, which provided the groundwork for his research program focusing on the Immunobiology of Inflammatory Syndromes and Aging. He has held several fellowships throughout his career. Dr. de Vallejo's previous academic appointments included serving as Assistant Professor of Medicine and Associate Consultant in Rheumatology at the Mayo Clinic College of Medicine.

Scientific research has defined Dr. de Vallejo's career. Among the current research topics are:

  • T cell-mediated immunopathway(s) of arthritis and myositis
  • Lymphocyte senescence
  • Immune mechanisms underlying successful aging
  • Immune-endocrine regulation of longevity
  • Immune repertoire changes in obesity and chronic infection
His research program is funded by grants from the Nancy E. Taylor Foundation for Chronic Diseases, the American Federation for Aging Research/Ellison Medical Foundation, and the National Institutes of Health.
 
Dr. de Vallejo is the author and co-author of numerous articles that have been published in leading scientific journals. He was associate editor of the Journal of Immunology (2000-2005), and was a special issue editor of Aging Research Reviews (2010-2011). Beginning in 2011, he became a member of the Editorial Boards of two journals: Rheumatology Current Research and Aging and Disease. He is a reviewer for several scientific journals, and has served (and continue to serve) as member of various research advisory councils and study sections of private foundation and federal funding agencies including those of the Department of Veterans Affairs and the National Institutes of Health. Dr. de Vallejo is fellow of The Royal Society of Medicine.
