The Kirkwood lab studies the diversity and function of aquatic ecosystems along natural to increasingly human-modified landscapes. This research encompasses a broad spectrum of surface waters, including lakes, wetlands, rivers, creeks, and stormwater ponds. For all habitat types, research focuses on the base of the foodweb (i.e., bacteria, algae, zooplankton, macroinvertebrates, and macrophytes). Algal biotechnology is another facet of research in the Kirkwood lab, and aims to discover useful applications for algae in biofuel production, carbon sequestration, and wastewater treatment.
