My research interests and and expertise are in clinical trials. I provide biostatistical and methodological leadership in clinical trials in and have served as the lead biostatistician for several multi-centre trials in various clinical areas including cancer, venous thrombosis, surgery, and emergency medicine. For a list of trials that are coordinated by the Ontario Clinical Oncology Group click here.

I have an interest in oversight committees for clinical trials and have served on several data safety monitoring boards and trial steering committees.
