Julie LaRoche (born 1957) is a Canadian marine biologist. She is a Tier 1 Canada Research Chair in Marine Microbial Genomics and Biogeochemistry at Dalhousie University.

Early life and education

[edit]

LaRoche was born in Quebec, Canada, in 1957. She earned her Bachelor of Science from McGill University and her PhD in Biological Oceanography at Dalhousie University.[1] While earning her PhD at Dalhouse, she met her future husband Douglas Wallace.[2]

Career

[edit]

After completing her postdoctoral studies at Dalhousie University, LaRoche conducted research at the Brookhaven National Laboratory (BNL).[1] While there, LaRoche co-published “Flavodoxin expression as an indicator of iron limitation in marine diatoms" with Helen Murray-Tobin which earned them the Luigi Provasoli Award from the Phycological Society of America for the most outstanding research paper published in the Journal of Phycology.[3] She also studied how stress affects phytoplankton.[4] In 1998, LaRoche accepted a position at the University of Kiel as a professor in their Institute of Oceanography.[1]

LaRoche and her husband stayed in Germany until 2010 when they both accepted placements at their alma mater, Dalhousie. LaRoche was appointed a Tier 1 Canada Research Chair in Marine Microbial Genomics and Biogeochemistry, and her husband was appointed the University's Canada Excellence Research Chair.[5] Upon her return, she developed a lab to research how global climate change is affecting marine microbes and biochemical processes.[6] She specifically studied how phytoplankton and marine bacteria are affected by increases in temperature and decreases in pH.[7] In 2016, she received $149,900 in funding for her plankton research project, which allowed her to purchase a holographic microscope for a commercial ship she uses to study the Deep Panuke drilling station.[8] Previously, her team had only been able to analyze sample of water twice a year until The Atlantic Canadian company voluntarily provided the lab with free access on the Atlantic Condor.[9] The next year, she partnered with Canada C3, a 150-day expedition along the Atlantic, Arctic and Pacific coasts, to collect and share data.[10]

In 2019, LaRoche was renewed as a Canada Research Chair.[11]

To date, LaRoche has published over 170 academic publications, which have been cited over 30,000 times, resulting in an h-index of 70.[12]
