معرفی
Dr. Lance F.W. Lesack is a Professor in the Departments of Geography and Biological Sciences at Simon Fraser University (SFU), specializing in limnology and biogeochemistry of inland waters. His research focuses on Arctic and tropical ecosystems, particularly the Mackenzie River Delta, where he studies methane dynamics, hydrology, and climate change impacts. He holds a BSc from the University of Manitoba (Zoology & Statistics) and a PhD from the University of California, Santa Barbara (Limnology & Hydrology). A key collaborator in the IPY-SCARF project, Lesack emphasizes the role of river-floodplain interactions in shaping Arctic lake ecosystems. He teaches courses in Limnology, Biogeochemistry, and Analytical Tools in Biogeochemistry, and actively mentors graduate students and researchers. His work bridges field observations with process-based modeling, addressing topics like greenhouse gas fluxes, dissolved organic matter sources, and microbial ecology in polar regions.
- Education: BSc (1977), University of Manitoba; PhD (1989), University of California, Santa Barbara
- Affiliations: SFU Geography and Biological Sciences Departments; Adjunct Researcher, Canadian International Polar Year (IPY) projects
- Labs/Teams: Mackenzie Delta Limnology Group; WETMETH Model Development Team
Research Interests: Arctic delta biogeochemistry, methane emissions, floodplain lake dynamics, global change impacts, and hydrological connectivity. Recent work highlights methane dynamics in Arctic lakes, river-ice breakup patterns, and mercury transport in Arctic rivers.
Grants & Collaborations: Lead or co-investigator on projects funded by NSERC, IPY, and international partnerships. Collaborates with institutions like the University of Alberta and the University of Manitoba on delta hydrology and climate studies.
