Brief Biography

Dr. Alman is the A.J. Latner professor and chair of Orthopaedics at the University of Toronto, vice-chair research of the department of Surgery, and the interim head of the Toronto Musculoskeletal Center.  He is also the head of Orthopaedics and a Senior Scientist in the Developmental and Stem Cell Biology Program at the Hospital for Sick Children.  His practice focuses on the care of children with syndromes, with spinal deformity, with neuromuscular disorders, and with tumors involving the bones, joints and soft tissues. He is an orthopaedic consultant at the Holland Bloorview Kids Rehabilitation Hospital and in the Multidisciplinary Musculoskeletal Tumor clinic and the Bone Health Centre at the Hospital for Sick Children.

He runs an active basic science research program, studying the role of developmental signaling pathways in musculoskeletal tumors and reparative processes.  He is the principal investigator on several national research grants, and has over 100 peer reviewed publications in Journals such as Lancet, Cancer Cell and Nature Medicine. He has given over 150 presentations at international meetings or at invited lectures at various venues throughout the world.

Dr. Alman was born in Philadelphia and studied at the University of Pennsylvania, Jefferson Medical School, Pennsylvanian Hospital, and Tufts University before undertaking a clinical and research fellowship at the Hospital for Sick Children in Toronto, where he has been on faculty the past 15 years.  He has received numerous awards for his research work over the years, including the Premier’s Research Excellence Award (for outstanding research work in Ontario), the Huene Award (for outstanding contributions to Pediatric Orthopaedics), the OREF Research Award, the Royal College Medal in Surgery (for the best research publication by a member) and most recently the Lodwick Award from Harvard University and Massachusetts General Hospital for the best publication in the musculoskeletal field.

In addition to his research and clinical activities, Dr. Alman serves on the Research Advisory Board and chairs the clinical research subcommittee of the Shriner’s Hospitals, and is a member of the Board of Trustees at the Holland Bloorview Kids Rehabilitation Hospital, which is the largest hospital in Canada treating pediatric disability.  

Research Interests

• Musculoskeletal neoplasia
• Musculoskeletal growth and repair
• Neuromuscular disorders

Our laboratory studies the molecular mechanisms responsible for the deregulation of cellular growth control in aggressive fibromatosis (desmoid tumour) and cartilage neoplasms (e.g. chondrosarcomas). We identified developmental signaling pathways that are inappropriately activated in both types of lesions. Our current work focuses on determining somatic mutations that may be responsible for the activation, identifying novel mediators in the signaling pathways, and determining if a pharmacologic approach can be used to modulate the pathway activation. The long-term goal of this work is to develop novel pharmacologic therapies for these otherwise difficult to treat lesions.

Some of the information learned from our work on tumours can be applied to repair processes and bone growth. We are currently working to determine how these signaling pathways regulate normal bone growth and wound healing.

Future Research Interests

To determine genes responsible for paediatric orthopaedic disorders (eg. congenital scoliosis)
