On the shore, Volkan Isler follows the action as two graduate research assistants launch a second boat.

Today Isler, an associate professor of computer science at the University of Minnesota, and graduate students Pratap Tokekar and Josh Vander Hook have come to the lake to test the newer of the boats. Their mission: developing a new technology to track invasive fish. (more…)
