Internship Opportunity: NSF REU in Fluvial Biogeochemistry

800 532 Stroud Water Research Center

A National Science Foundation-funded Research Experience for Undergraduates internship in fluvial biogeochemistry is available for summer 2019 at Stroud Water Research Center under the direction of Drs. Diana Oviedo-Vargas and Marc Peipoch. NSF REU programs aim to actively involve undergraduate students in meaningful, ongoing research projects.

This internship is part of a long-term research project focusing on how carbon and nitrogen processes change over time after riparian reforestation in the context of a 40-year restoration on White Clay Creek performed by the Stroud Center. The REU will work closely with both principal investigators and their teams to assess how changes in carbon quality and streambed complexity associated with reforestation influence denitrification processes at multiple scales.

Program Overview

The REU participant will gain research experience in both ecosystem ecology and fluvial biogeochemistry, while being part of a broader multidisciplinary team at the Stroud Center. Field work will combine surveys of multiple benthic habitat types, sediment incubations, and the use of in-situ spectrophotometers (S::CAN) that collect stream water absorption spectra at high-frequencies. Project findings will provide insights on the effectiveness of riparian reforestation for the recovery of valuable ecosystem services such as nitrogen removal (denitrification).

  • Location: Stroud Water Research Center, 970 Spencer Road, Avondale, Pennsylvania. Please note that this is a rural location and not near a public transportation system.
  • Program duration: this is a 10-week internship. The internship must begin before June 10, 2019.
  • Stipend: the successful candidate will receive $5,000 and free on-campus housing at the Stroud Center.
  • Qualifications: undergraduate students with a 3.0 GPA or higher. Participants must be U.S. citizens, U.S. nationals, or permanent residents of the United States.
  • Deadlines: application period ends March 29, 2019. Selection will be made on April 2.


The REU will participate in fieldwork, sample processing, data analysis, and regular lab group meetings. At the end of the internship, the REU will be expected to create an oral presentation for the summer REU meeting at the Stroud Center and for a professional scientific meeting in case this opportunity presents itself.

Application Process

Interested candidates should provide:

  • a maximum one-page cover letter,
  • a maximum two-page resume detailing any previous research experience,
