Work E-mail: email@example.com
Dr. Colantonio completed his undergraduate and PhD (Physiology 2004) degrees from Queen’s University, Kingston. Following his graduate studies he completed a clinical postdoctoral fellowship in Clinical Biochemistry at John’s Hopkins University, School of Medicine, Baltimore (2006). Dr. Colantonio is certified as a specialist in Clinical Chemistry and is a fellow of both the Canadian Academy of Clinical Biochemists and the American Academy of Clinical Chemists. He is currently an Assistant Professor in the Department of Pathology and Laboratory Medicine and a Clinical Biochemist at the Ottawa Hospital where he directs the HPLC lab and porphyrin testing. His specialty is in therapeutic drug monitoring and toxicology; he is currently in the process of setting up a clinical therapeutic drug monitoring and toxicology lab using mass spectrometry.
In addition to his work in laboratory medicine, Dr. Colantonio has extensive experience teaching, supervising graduate students and conducting research. His research is in the area of therapeutic drug monitoring and pharmacokinetics. Dr. Colantonio is a member of the DLAC (Drugs in Lactation) research group based at the Hospital for Sick Kids in Toronto, where he spent the last 10 years working as a clinical biochemist and conducting research at the University of Toronto. His research focuses on investigating the excretion of drugs into breast milk and assessing the potential risk it may pose to nursing infants. The first step in assessing drug safety during breastfeeding is to measure drug concentrations in breast milk; this is accomplished by developing analytical methods to measure drug concentrations with mass spectrometry. These drug concentrations are then modeled, using population PK analyses (Non-linear Mixed Effects Modeling), to determine how much drug an infant would ingest, and consequently, assess the risk of drug exposure to the nursing infant.
