His PhD thesis solved a mystery — and may help turn a lake blue again

Growing up, Eli Hall’s family often visited the Allegheny Reservoir, a man-made lake that straddles the border between Pennsylvania and New York. Driving north along the shores, they’d see blue waters, boaters, swimmers, everything you’d expect from a summer lakeshore.

In their place was a mess of green algae. But why?

Having just earned his PhD from the University of Pittsburgh, Hall finally has his answer. Along with it, he found a calling to use science to help people.
