Description of Research


My research is often linked to my function as director of the CNRU Mass Spectrometry Core. We are constantly making an effort to develop new analytical and translational technologies and strategies including quantitative mass spectrometry assay for drugs, drug metabolites and endogenous compounds, non-targeted and targeted strategies for metabolic profiling (metabolomics) and the targeted quantification, multiplexing and non-targeted profiling of proteins (proteomics). These technologies are made available to CNRU investigators. In addition, we develop assays as requested by CNRU investigators.

My personal research interests are in the areas:

- transplantation and immunosuppression

- cholesterol-lowering drugs

- vascular endothelial dysfunction

- drug eluting stents

- pharmacokinetics and drug metabolism

- therapeutic drug monitoring

- the role of drug metabolizing enzymes and transporters in barriers (e.g. gastro-intestinal barrier and the blood-brain barrier)

Benefit of CNRU

The major benefit of the CNRU for me has been the enhanced interaction and collaboration with other CNRU investigators. Additionally, the CNRU allows me to interact with junior investigators through the pilot project program and through the core laboratories.  The core laboratories of the CNRU are critical to my research success.  These laboratories provide with services and expertise that are beyond the capabilities of my own research group/ laboratory.
