Current Research Projects

Stream 1: Urine metabolomics for biomarker discovery in respiratory illness: Asthma and chronic obstructive pulmonary disease (COPD) are common respiratory illnesses that reduce the quality of life and can result in premature death. Asthma, in particular, is common among young children, a vulnerable population that cannot perform conventional clinical diagnostic tests.

In collaboration with Dr. Darryl Adamko, College of Medicine, University of Saskatchewan, we are developing untargeted and targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for the analysis of urinary metabolites that are linked to respiratory illnesses. Our objectives are to identify potential metabolite biomarkers and develop clinically approved targeted methods for biomarker qualification. The end goal is to develop clinical MS-based testing that can aid in disease diagnosis and therapy management. 

Stream 2: Advancing the Use of MALDI-MS for the Analysis of Small Molecules: Matrix assisted laser desorption ionization-mass spectrometry (MALDI-MS) is a simple and fast analytical strategy. MALDI-MS analysis, however, is hampered due to the use of matrices that commonly interferes with the analysis of small molecules and metabolites (MW< 1000 Da). Choosing the right matrix for small molecules is tedious and time-consuming. We are, therefore, developing new surface- modified nanostructures as novel MALDI matrices. We demonstrated in the past that newly designed matrices are superior to conventional matrices when analyzing low molecular weight pharmaceuticals. Analyte signal was enhanced while background noise, commonly observed with conventional matrices, was reduced. We are currently focusing on developing new matrices with various surface modifications and applying them to the analysis of substance of abuse in both urine and plasma. This work can expand the use of MALDI-MS for the qualitative and quantitative analysis of small molecules.

Stream 3: Analysis of psychoactive compounds: Our work, in collaboration with Dr. Robert Laprairie, is focused on developing targeted and profiling mass spectrometric methods to quantify and identify bioactive substances, present in natural psychoactive plants, such as marijuana and magic mushrooms. We are developing tandem mass spectrometric (MS/MS) fingerprints of cannabinoids form cannabis that will be applied for the screening of additional metabolites within plant and animal tissues. In addition, validated targeted LC-MS/MS methods is being developed for preclinical testing of various plant extracts within animal models of pain.

Stream 4: Extraction of active metabolites from canola oil waste stream: Canada is a major world producer of canola oil. By-products from the crushing and refining process are either treated as waste or low value products. Our analysis revealed that the waste stream contains around 5-10% phytosterols and 2% tocopherols. Therefore, extracting high value compounds particularly phytosterols from canola oil waste stream represents an important value-added opportunity. We are developing industrial extraction strategies to isolate biologically active metabolites from canola’s waste stream without the use of toxic solvents. LC-MS/MS methods were developed to profile the various extracts and nanotechnology were employed to formulate the isolated active metabolites into functional foods. We also devised strategies to prevent the formation of harmful phytosterols oxidation produces (POPs) during the whole process from extraction to formulation.
