Brief Biography

Dr. Alman runs a basic science research program, studying the role of developmental signalling pathways in musculoskeletal tumor and reparative processes.  He is the principal investigator on several national research grants, and has over 125 peer reviewed publications in Journals such as Lancet, Cell and nature Medicine.  He has given over 150 presentations in international meetings and at invited lectures at various venues throughout the world. Dr. Alman has recently moved to the University of North Carolina but continues to be associated with the SickKids Research Institute as an adjunct scientist. 

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, where he has been part of the faculty the past 15 years.  he received numerous awards for his work over the years, including the Premier's Research Excellence Award for outstanding research work in Ontario, the Heune Award for outstanding contributions to Pediatric Orthopaedics, the OREF Research Award, the Royal College Medal in Surgery for best research publication by a member, the Lodwick award from Harvard University and Massachusetts General Hospital for the best publication in the musculoskeletal field and the Association for Surgical Education's 2102 Award for Excellence in Innovation. 

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)

Achievements
