Professor Christa Kelleher ’08 and her students are uncovering the hidden story of Lehigh Valley’s local streams through NSF-supported temperature research. The data they’re collecting will eventually reveal much about the health of the Bushkill Creek and the Delaware River watershed. There’s an abundance of publicly available water temperature data from the U.S. Geological Survey but little from the Lehigh Valley area. This research aims to correct that. This summer, work began in earnest on Kelleher’s five-year, $489,451 National Science Foundation Faculty Early Career Development Program (CAREER) award, the agency’s most prestigious recognition of early-career faculty. As an alumna, Kelleher enjoys being with students as she relives good memories of conducting similar research when she was a student at Lafayette.
