Dr. Poirier joined us from Canada in 2016 from the Tom Baker Cancer Centre where he was a Physicist. He currently divides his time between clinical physics support at the University of Maryland Medical Centre and the Division of Translational Radiation Science, where he provides physics support for the small-animal radiation research platform (SARRP). He specializes in the modeling and experimental dosimetry of low-energy kilovoltage x-ray sources. Dr. Poirier is board-certified by both the Canadian College of Physicists in Medecine (CCPM) and the American Board of Radiology (dABR).

Research/Clinical Keywords

kilovoltage x-ray dosimetry, CBCT imaging dose, experimental dosimetry
