Academic & Clinical Interests

• Central nervous system tumours and stereotactic radiosurgery
• Treatment of spinal/paraspinous tumours
• Spinal cord myelopathy, the consequence of small volumes receiving high doses to predict for organ dysfunction

Current Research Projects

• Evaluation of new radiation technologies for spine stereotactic body radiotherapy in multi-institutional planning studies
