Justin Liefer

Justin Liefer is an Assistant Professor in the Department of Biology at Mount Allison University. His research focuses on marine phytoplankton ecology, particularly their physiological responses to environmental stressors such as climate change, nutrient availability, and toxicological pressures. He investigates cellular-level mechanisms that influence large-scale biogeochemical patterns, with a strong emphasis on elemental stoichiometry, macromolecular composition, and harmful algal blooms. His work integrates experimental approaches with field observations and mathematical modeling. Dr. Liefer’s expertise includes phytoplankton acclimation strategies, toxin production in dinoflagellates, and the impacts of submarine groundwater discharge on coastal ecosystems. He has published extensively on topics ranging from diatom temperature adaptation to ciguatera toxin dynamics in Caribbean waters.

His research interests are centered on understanding how microorganisms respond to environmental changes, with applications to global carbon cycles and ecosystem health. Key themes include nutrient limitation effects, climate change impacts on marine organisms, and the interplay between phytoplankton physiology and ecosystem function. His studies often bridge micro-scale cellular processes with macro-scale ecological patterns, providing insights into both fundamental biology and applied environmental management.

While no specific grants or awards are listed, his publication record demonstrates sustained contributions to marine microbiology and biogeochemistry. His teaching and advising focus align with his research areas, emphasizing hands-on laboratory techniques and field-based ecological studies.
