The Molecular Function and Imaging Program of the University of Ottawa Heart Institute Presents:



7th Annual MFI Symposium: Call for Abstracts



Please join us on June 19th and 20th 2014, at the beautiful Ottawa Convention Centre, for the 7th Annual Molecular Function and Imaging (MFI) Symposium. The MFI Symposium will bring together multidisciplinary fields to discuss exciting new advances in the development and application of imaging for the study, detection and treatment of cardiovascular disease. The event offers the perfect platform for young scientists to interact with leading experts in the field and network with future mentors and collaborators.

Complementary Registration Fee for all trainees submitting an abstract. Submit your abstract TODAY! Abstract submission closed 23 May 2014. For more information see: http://www.ottawaheart.ca/research_discovery/mfi-symposium_about-mfis.htm 

Trainees, Research Staff, and New Investigators from outside the Ottawa area who are working on CAIN or MITNEC-related projects who wish to receive partial support to attend this meeting (flight and two-days of accommodation) are invited to concurrently 1) send their abstracts to This email address is being protected from spambots. You need JavaScript enabled to view it. prior to the 23 May 2014 deadline; 2) register as a user on imagingkt.ca; and 3) provide an introduction on the Welcome Mat board in the Forum section of imagingkt.ca

 

The Tri-Council is a unified body of the three federal granting agencies; Canadian Institutes for Health Research (CIHR), the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Social Sciences and Humanities Research Council of Canada (SSHRC). Together, they offer an impressive funding opportunity to graduate students before or within their first year of graduate education. If you are interested in graduate science or medical education further to some of the courses and materials we offer here, more information is here.

ImagingKT is made possible through the invaluable participation and collaboration of our continuously growing community of contributors from across Canada.

Research Focus

My research covers the molecular and genomic aspects of atherosclerosis and related diseases and also involves animal models, mechanistic and observational clinical studies as well as large international randomized clinical trials. I have been the international principal investigator or part of the study leadership of several large clinical trials in the field of atherosclerosis and other cardiovascular diseases. My team and I have created the Beaulieu-Saucier Pharmacogenomics Center at the Montreal Heart Institute and have created the Center of Excellence in Personalized Medicine, the latter funded by the Network of Centers of Excellence of Canada and which is also supported by multiple pharmaceutical and biotechnological companies. I am one of the founding members of the Critical Markers of Disease organization, which focuses on the development and better use of biomarkers (CMOD).

Research Focus

My research is based on uses of ultrasound in stroke prevention. We use transcranial Doppler for risk stratification in asymptomatic carotid stenosis and for detection of right-to-left shunts in patients with suspected paradoxical embolism, and measurement of carotid plaque burden for risk stratification, management of patients and genetic research. In CAIN I am chair of Project 2, which is validating preoperative imaging of vulnerable plaque by 3D ultrasound, MRI, CT angio, contrast studies of plaque vascularity and PET/CT imaging of plaque inflammation,  with 3D histology of carotid endarterectomy specimens.

I have been greatly influenced by Dr. Henry Barnett, with whom I trained in Neurology. He was the first to show that aspirin reduced the risk of stroke, was PI of the North American Carotid Endarterectomy Study, and a giant in stroke prevention. My greatest personal achievement has been the prevention of approximately 7000 strokes among the 30,000 patients referred to me;  my greatest academic achievement has been the pioneering of measurement of carotid plaque burden for risk stratification, management of patients and genetic research.
