Cancer remains a major public health challenge in Canada and around the world. The Canadian Cancer Society projects that 1 in 2 Canadians will develop cancer at some point in their lifetimes, and 1 in 4 will die from their cancer. Cancers most often result from permanents alterations in the genomic DNA (i.e., mutations), which can lead to uncontrolled cell growth and division. We are very interested in elucidating the molecular origins of mutations derived from DNA damage, with an eye toward understanding mutagenesis in cancers. We use a combination of wet lab and computational approaches to derive insights into these questions. We are also very interested in using cancer hypermutation as a genetic engineering tool in microbes, such as budding yeast. Currently, we are investigating the potential of using a cancer hypermutator enzyme called APOBEC3A as a means to generate more productive biofuel yeasts. Opportunities are available to pursue graduate studies in these and related topics.
