WEST LAFAYETTE, Ind. – Purdue University will administer the Illinois-Indiana Sea Grant College Program (IISG), previously managed by the University of Illinois, effective Feb. 1, 2018. New IISG director Tomas Höök, a fisheries biologist in Purdue’s Department of Forestry and Natural Resources, will lead the administration.

IISG research, outreach and education efforts bring the latest science to southern Lake Michigan residents and decision makers and empower them to secure a healthy environment and economy.

The program has been a leader in the region on aquatic invasive species control, pollution prevention and Great Lakes literacy, and has developed decision tools that help communities grow while protecting natural resources. Illinois-Indiana Sea Grant supports more than 50 permanent medicine collection programs in the Great Lakes region, has helped the Indiana aquaculture industry grow fivefold and provides resources for municipalities to plan for future water supplies.

IISG is funded through the National Oceanic and Atmospheric Administration (NOAA), Purdue University and the University of Illinois.

Tomas Höök, Director

“While Illinois-Indiana Sea Grant has recently been administered by the University of Illinois, it has always been a truly bi-state program,” says Höök, who has served as IISG’s associate director for research since 2010. “For the past 16 years, the program has greatly benefitted from IISG leadership at Illinois, especially Brian Miller and Lisa Merrifield. With program administration moving to Purdue, IISG will continue to work to empower Lake Michigan communities in both Illinois and Indiana through applied discovery and information dissemination.”

Purdue University and the University of Illinois have worked closely to oversee IISG since 1982, periodically transferring the program directorship. Over its 36 years, the program has maintained an administrative presence at both universities.

“When I started my career with Sea Grant in 1994, we were going through an administrative transition similar to the one happening right now,” says Brian Miller, who has been program director for 11 years and is now retiring. “What we have accomplished since that time provides a wonderful platform for even greater growth in the future.”

IISG is part of the National Sea Grant College program, established in 1966 to protect and preserve America’s coastline and water resources to create a sustainable economy and environment. The network consists of a partnership between NOAA and 33 university-based programs in every coastal and Great Lakes state.
