Dr. Orchard is an Associate Professor of Pediatrics in the Division of Hematology-Oncology and Blood and Marrow Transplantation. He is the Medical Director of the Inherited Metabolic and Storage Disease Bone Marrow Transplantation Program.

Dr. Orchard received his M.D. degree from the Brown University Program in Medicine in 1984, and completed his training in Pediatrics at the University of Wisconsin in Madison in 1987. He did his fellowship training in Hematology-Oncology and Bone Marrow Transplantation in Minnesota, and joined the faculty at the University of Minnesota in 1990. He is board certified in Pediatrics and Hematology/Oncology.

Dr. Orchard has been interested in the use of hematopoietic cell transplantation for genetic metabolic and storage diseases. A particular interest has been osteopetrosis, an inherited disorder leading to increased density of bone, which is also amenable to treatment with transplantation. He is considered an International expert in this disorder and its treatment. Another focus has been gene therapy approaches in association with transplantation or other cellular therapies. Dr. Orchard has developed methods of introducing genes into donor T cells to allow their administration to assist the recovery of the immune system, while providing the opportunity for elimination of the genetically engineered cells if complications occur. This strategy will be used to increase the safety of cellular therapies. Additional activities include a role as co-chair of the Institutional Review Board of the National Marrow Donor Program (NMDP) and participation in the University of Minnesota Data and Safety Monitoring Council (DSMC), the Children's Oncology Group and the Pediatric Blood and Marrow Transplantation Consortium.

Dr. Orchard has published over 50 research manuscripts in medical journals, including: New England Journal of Medicine, Blood, Bone Marrow Transplantation, Journal of Bone and Mineral Research and Nature Genetics.
