About Me ...

At WIU, I direct the Institute for Environmental Studies (IES) and am Chair of Western’s interdisciplinary Ph.D. program in Environmental Science.

My work bridges the gap between environmental engineering and environmental science/ecology.  For over 20 years, I’ve designed, conducted, and led large-scale environmental assessments that involve stakeholders from a variety of academic, regulatory, and nongovernmental organizations.  My goal is to integrate extensive field investigations with laboratory studies and modeling to develop remediation approaches that result in lasting improvements to the quality and resilience of natural aquatic systems.  Due to the scope of these topics, I typically work with a multidisciplinary team of biologists, engineers, geographers, geologists, and planners, among others.

In addition to my position at Western, I’ve served as the President of the Aquacultural Engineering Society (AES) and continue to serve on the editorial board of the Journal of Aquacultural Engineering.  I was also the panel manager for the U.S. Department of Agriculture’s Aquaculture Small Business Innovation Research (SBIR) Program.

Since my work cuts across several traditional academic disciplines, I've found that it's important to establish and maintain professional credentials that complement my education; to that end, I'm a Board Certified Environmental Engineering Member (BCEEM) of the American Academy of Environmental Engineers and Scientists (AAEES) and an Ecological Society of America Certified Senior Ecologist (CSE).

My Recent Work ...

Take a minute to learn about our new water level sensor systems which were provided by the Moline Conservation Club.  These systems are solar-powered and are controlled via a 4G cell signal.  This allows us to monitor water levels and the microclimate in the vicinity of the sensors on a 24-7 basis!

Installing the senors -

Water level monitoring - 5 inches of rain over 24 hours -
