Education

Research interests

My PhD research involves improving the Systematic Evolution of Ligands by Exponential enrichment (SELEX) process using a combination of experimental and computational methods. I am also applying the improved SELEX technique to produce aptamers that can recognize and bind to mycotoxins (fungal metabolites) with high affinity. It is estimated that at least 25% of the grain produced worldwide is contaminated with mycotoxins. In Canada, three mycotoxins of major concern include fumonisin B1 (FB1), deoxynivalenol (DON) and ochratoxin A (OA). Mycotoxin exposure leads to a variety of pathologies including vomiting (DON); kidney disease (OA, FB1); neurological disorders (FB1); disease of the lung and liver (FB1); cancer (OA, FB1) and death (FB1, OA). While traditional food safety testing techniques to detect mycotoxins exist; there is a need for more rapid and cost-effective approaches. We expect that the relatively new technology of aptamers is a viable alternative for use in food testing, specifically for mycotoxin detection.
