Research Interests

The Cancer Cell Laboratory focuses on two projects:

1. The Prairie to Pharmacy Project. We are investigating plant species from the prairie ecological zone for novel anti-cancer compounds. To date, we have identified 12 species with interesting properties. This is a multidisciplinary project that includes collaborators with international pharmaceutical companies.

2. Checkpoint Adaptation project. We examine how cancer cells respond to cancer treatments. We are testing the hypothesis that cancer cells escape a cytotoxic treatment by a pathway known as "checkpoint adaptation" (entering mitosis with damaged DNA). To test this, we use cultured human cells and cell biological techniques such as microscopy, RNA interference, transfection and Western blotting.

Interested students and recent PhD graduates are invited to apply for research positions.
