Appointment Status

Dr Peter Sabatini completed his Doctoral degree at the University of Toronto with Dr Michelle Bendeck and Dr Lowell Langille studying the mechanisms of cell motility in the cardiovascular system.

He was awarded an Industrial Postdoctoral Fellowship where he developed genomic assays with Luminex Molecular Diagnostics.

He then completed his molecular and cytogenetics specialty training with the Canadian College of Medical Geneticists at The Hospital for Sick Children in Toronto.

Dr Sabatini is currently a dual certified (molecular/cytogenetics) clinical laboratory geneticist at the University Health Network focusing on cancer genomics.


Research Synopsis


My primary research interests are the genomic alterations that contribute to oncogenesis include both molecular changes and also larger microscopically visible ones.

Many methods are used in the clinical laboratory to discover the range of genomic variations that drive cancer development and drug resistance. This creates lengthy and cumbersome clinical testing algorithms.

Using advanced genomic technologies such as applications of next-generation sequencing methods, my focus is to simultaneously investigate the sequences of both DNA and RNA targets to detect the full range of genomic alterations in solid tumours and hematological malignancies.

The goal is the use novel genomic technologies to streamline and integrate the genetic tests of tumours into the clinical diagnostic laboratory.

Our laboratory includes both a clinical service laboratory at the Toronto General Hospital and a translational research site called the Advanced Molecular Diagnostic Laboratory at the Princess Margaret Hospital.
