I use theory, experiments, and observational studies to understand the causes and consequences of changing biodiversity in the modern era.

I study how diverse aquatic communities simultaneously affect and are affected by anthropogenic chemicals, including engineered nanoparticles.

I study how ecological mechanisms of coexistence regulate the impacts of biodiversity on the functioning and stability of ecosystems.

I am interested in how evolutionary and ecological processes interact to generate biological diversity, and how those interactions control the ecosystem level consequences of diversity fluctuations.

I am interested in the factors that influence assembly, disassembly (biodiversity loss) and restoration of aquatic communities that are impacted by human activities.

Congratulations to Lindsey, who won an NSF Dissertation Improvement Grant, as well as a Student Presentation Award at the 2010 North American Benthological Society meeting.

I am trying to determine how species diversity correlates with ecosystem services that have been measured in natural freshwater habitats throughout North America.

I not only manage the lab and keeps things running smoothly, I help run our new DIMENSIONS of Biodiversity grant that examines the evolutionary and genetic basis for ecosystem productivity.

Undergraduates in the lab conduct independent studies and provide assistance for ongoing projects, all mentored by the PI, postdocs and graduate students.

Congratulations to Lauren Koenig, who won the Best Student Presentation for Basic Research at the 2010 North American Benthological Society meeting.
