20 July 2021 – StFX Alumni News published a nice profile on Dr. Toxopeus and her lab’s research in their summer 2021 issue.

16 June 2021 – Congratulations to Jay Turnsek, whose summer research is featured in StFX news this week.

10 May 2021 – Welcome to Victoria Adams, a second-year undergraduate who is joining the Toxopeus lab this summer to study the sequences of ice-binding proteins in freeze-tolerant organisms! Victoria is funded by a McLachlan summer research award from the Biology Department at St. FX.

10 May 2021 – Congratulations to Trinity McIntyre, whose summer research project in the Toxopeus lab is partially funded by a Chiasson summer research award from the Biology Department at St. FX. Trinity will be studying how the cold tolerance of the apple maggot fly Rhagoletis pomonella differs from its multiple species of parasitoid wasps.

3 May 2021 – Welcome to Maranda van Oirschot, a second-year undergraduate who is joining the Toxopeus lab this summer to study how the cytoskeleton of freeze-tolerant crickets! Maranda is co-supervised by Dr. Bill Marshall and partially funded by a McLachlan summer research award from the Biology Department at St. FX.

3 May 2021 – Welcome to Jay Turnsek, a second-year undergraduate in computer science who is using machine learning to better classify CRISPR sequences! Jay is co-supervised by Dr. James Hughes and is funded by an Ally Heaps summer research award from the Computer Science Department at St. FX.

16 April 2021 – Excellent news: the Toxopeus lab has received NSERC Discovery Grant funding (along with a Discovery Launch supplement for early career researchers) that will help fund projects on insect freeze tolerance for the next five years!

24 February 2021 – New publication on the gene expression of a Beringian pseudoscorpion, with excellent co-authors from Western University.

8 February 2021 – Manuscript accepted for publication in Comparative Biochemistry and Physiology! Our research on the diapause and cold tolerance physiology of the apple pest Rhagoletis pomonella is now available here, with much of the work conducted by talented undergraduate students Lalitya Andaloori and Matin Sanaei in the Ragland lab at CU Denver.

20 January 2021 – Welcome to Trinity McIntyre, a third-year undergraduate student who is joining the Toxopeus lab this semester!

8 January 2021 – We can officially share the news! Dr. Toxopeus has received funding from Research Nova Scotia to study the incidence of COVID-19 in wastewater as part of a province-wide research project with researchers at St. FX, Dalhousie University, Acadia University, and Cape Breton University. You can read more here.

3 January 2021 – Today marks the start of the SICB (Society for Integrative and Comparative Biology) virtual annual meeting! Dr. Toxopeus’ research talk on the surprising interactions between low temperatures and insect diapause can be viewed here.

26 November 2020 – Thanks to WISE Atlantic for inviting Dr. Toxopeus to be a panelist in their “Stepping Forward” career workshop for female postdocs in STEM – lots of talented and motivated women in attendance who are ready to take the job market by storm!

9 November 2020 – Thanks to the folks in Mt. Allison Chemistry and Biochemistry for inviting Dr. Toxopeus to give a seminar today! It was great to chat with some chemists about the phenomenon of insect freeze tolerance.

31 October 2020 – Two big grants submitted this fall to fund research on insect freeze tolerance. It was a bit of a marathon but hopefully it produces results!

21 August 2020 – Can finally share the news that Drs. Toxopeus, Bishop, and Wyeth secured Canadian Foundation for Innovation funding to buy a brand new confocal microscope for the Biology department
