Planky the Planktoscope is on the move! Planky joined PhD candidates Loay Jabre and Scott Pollara on the RV Celtic Explorer to take some snapshots of all of the photo-ready critters in the NW Atlantic Ocean. Say photosynthesis! Here is a phaeocystis colony (top right) and a Chaetoceros chain (bottom right) captured by Loay. Read more about his time at sea here

New Paper: Fe and temperature interactions in diatom growth

May 25, 2020
PhD student Loay Jabre leads this new work- We found that temperature and iron interactively influence growth in an important polar diatom - warming alleviated Fe demand, allowing cells to maximize growth under low Fe availability

If I can see her, I can be her. Developed by Ingenium – Canada’s Museums of Science and Innovation, the National Film Board of Canada (NFB), Fisheries and Oceans Canada, and the Canadian Museum of Nature, #MySTEMjob tells the stories of twenty inspiring women from across Canada through video shorts designed to spark curiosity in young women and inspire them to pursue STEM careers.


Just Accepted! Journal of Proteome Research- Prediction and consequences of cofragmentation in metaproteomics

September 6, 2019
Congratulations PhD student Scott McCain- first thesis chapter published. Metaproteomics, almost by definition, is more complex than single-organism proteomics. One of the consequences of this complexity is messy spectra - when two peptides are selected together and produce overlapping 'fingerprints' (MS/MS spectra). This paper empowers proteomics researchers to understand biases arising from this complexity.


Welcome new PDF Insa Rapp, PhD students Cat Bannon and Charvanna Dhoonmoon, and MSc student Megan Roberts!

Exciting times in the lab- we're growing!


August 9, 2019
In a new paper led by postdoctoral scholar Miao Wu and PhD student Scott McCain, our lab has led a collaboration that identifies manganese as a key micronutrient for shaping primary productivity in the Southern Ocean


Congratulations on successful honours degrees Catalina Albury and Tor Kitching! We couldn't be prouder

Thankfully, they aren't going too far!


PhD student Loay Jabre wins best Biology Department Pi Day Pie, and a Lett Symposium Research Talk award!

April 5, 2019
Loay's been busy growing diatoms and perfecting his baking skills! He's won first place in our Departmental Pi Day Pie contest (winning pie shown on right) and one of three prizes for best research talk at the Dalhousie Biology Graduate student-led 2019 Lett Symposium. Congratulations Loay!
