RESEARCH

My research interests are centered around management and conservation of freshwater resources.  I am especially interested in aquatic invertebrate and fisheries ecology, ecosystem restoration, watershed management, and aquatic ecosystem linkages.

There are many opportunities for senior thesis projects, so I would encourage interested students to contact me ([email protected]) to discuss their interests further.

Past and Ongoing Research


Phenology and Health of Migratory Fishes in Lake Superior Tributaries
Collaborators: P. Ripple (Bay Mills Indian Community), K. Kapuscinski and J. Li (LSSU)
The goals of this research project are to: 1) characterize timing and size of in- and out-migrations by Great Lakes fishes in relation to temperature and discharge
, and 2) assess the physiological health of Great Lakes migrants

Conservation of native fish communities in tributaries to the Great Lakes: Predicting the impacts of contaminants delivered by spawning Pacific Salmon
Collaborators: D. Chaloner, G. Lamberti, & D. Pitts (Notre Dame), R. Rediski (GVSU)
The goal of this project is to evaluate the interactive effects of watershed condition and contaminant biotransport by introduced salmon on the contaminant load of stream resident fish. Data on if/how watershed factors influence uptake of contaminants by stream fish will inform conservation and management of fish in the Great Lakes basin.

Restoration of the Little Rapids, St. Marys River
Collaborators: GLC, NOAA, MDEQ, MDNR
A multi-institutional team is developing and implementing a habitat restoration plan to restore flow to the Little Rapids area of the St. Marys River and create  improved forage, nursery, and spawning habitat for riverine fishes.  LSSU scientists are leading the monitoring effort to evaluate the changes in physical and biological (benthic invertebrates and fish) after the restoration.

Great Lakes Coastal Wetland Monitoring Program
Collaborators: D. Uzarski (CMU), V. Brady (NRRI), M. Cooper (CMU), and others
The GLCWM Program is a Great Lakes-wide effort to assess the status of and trends in coastal wetland health.  LSSU and its collaborators are collecting physical, chemical, and biological data to develop indices of wetland health.  These indices will help prioritize coastal wetlands for future.
