Dr. Jantina Toxopeus
Principal Investigator
Funding: NSERC Discovery Grant, NRCan (Natural Resources Canada)
I am an associate professor at St. FX, where I love researching how insects survive winter and teaching biology. I take an integrative approach to research, explaining whole animal phenotypes (like being able to survive freezing) at many levels of biological organization (genes, cells, tissues, physiological systems).
