Personal statement:
I am a biological limnologist who studies the smallest animals in freshwater lakes. Research in my lab investigates how zooplankton are influenced by, and influence, abiotic and biotic processes. I use multiple techniques including field observations, laboratory experiments, and mathematical models to test hypotheses. My research also focuses on the North American invasion of non-native species such as the spiny water flea (Bythotrephes) and fish hook water flea (Cercopagis). Although the establishment of these species negatively impacts our lakes, their arrival does provide a lens to view biological process, such as establishment, evolution, and species interaction, which are otherwise difficult to elucidate. I am involved with mapping the spread of these zooplankters, exploring ways to limit their range expansion, and quantifying their effect on native species. Some of my most recent research explores the role of dormancy, often an obligate phase for freshwater zooplankton, in species dispersal and persistence. My study systems include the Finger Lakes, Lake Superior, Lago Maggiore (Italy), and a number of small lakes in North Minnesota and southern Ontario.
