Bertrand Lab

The Bertrand Lab at Dalhousie University employs physiological, biochemical, and bioanalytical approaches to improve our understanding of controls on marine microbial activity and how microbes influence major biogeochemical processes in the ocean.

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.

The first Science Meets Parliament event in Canada was held in November 2018 in Ottawa, where twenty-eight Tier II Canada Research Chairs (a specific class of Canadian university professor acknowledged by their peers as having the potential to lead in their field) from diverse disciplines met with forty-three Members of Canadian Parliament and Senators. The main goal of this event was to facilitate communication between these two key pillars of the society, to promote mutual understanding of the nature of their respective work, roles, and responsibilities, and to build long-term relationships. Here, we, representatives of the first cohort of scientists to participate in the program, summarize our experiences and lessons learned from this event, as well as our assessment of the benefits of attending this event for scientists, policy decision-makers, and institutions. Furthermore, we provide suggestions for similar future events in Canada and elsewhere.


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.
