I love lakes. The focus of my research is ecology and conservation of lake ecosystems. Lake ecosystems are often heavily impacted by human activities, including eutrophication, invasive species introduction, habitat destruction, and climate change. I'm trying to understand how human activities alter water quality and nutrient dynamics, aquatic communities, ecosystem functions, and ecosystem services, to inform management and conservation of lake ecosystems. I'm broadly interested in basic and applied issues, and work by mixing long-term observations, field and laboratory experiments, macroecological analysis, and stable isotope and genetic analyses. I like collaborative work! Finally, one of my responsibilities at work is Lake Kasumigaura Long-term Monitoring Project, which has been monitoring this lake over the past 40 years. Our monitoring data is available on our web database. If you are interested in our data, please feel free to ask.
