Recent Mansfield graduate, Josh Grassi ‘18,
has published findings of his senior research project in the peer-reviewed
journal Environmental
DNA, along with co-authors Dr. Gregory Moyer, associate professor of
biology at Mansfield; Chris Rees and Dr.
Meredith Bartron, U.S. Fish and Wildlife Service; and Dr. Heather Galbraith, U.S.
Geological Survey.
Grassi developed a molecular technique to detect the American
Eel under water. This technique termed “environmental DNA,” or simply eDNA, can
detect the presence of an organism, site unseen, simply by taking a water
sample.
“Josh’s work was instrumental in understanding whether this
technology could be used for practical field applications,” Moyer said.
Typically, eels are detected using nets or through
electrofishing, a process that uses direct currents of electricity under the
water to affect the movement of fish to swim toward a particular spot. Both
methods can be invasive or harmful to the eels; eDNA allows for a much safer
method of detection.
Grassi, who is employed by the Pennsylvania Department of
Environmental Protection as an aquatic biologist, said, “Having the opportunity
to conduct meaningful research while at Mansfield has opened many doors on a
personal and professional level. Through this project, I was able to learn
valuable lessons in following the scientific process, collaborating within a
work group, and presenting findings in a formal setting. These lessons were
invaluable in preparing me for the start of my career. I am beyond grateful for
what this research project has done for me and encourage anyone sharing similar
goals to learn more about the possibilities at Mansfield.”
“The collaboration between faculty and students on research
projects is an important part of the educational experience at our now combined
university,” said Commonwealth president Dr. Bashar W. Hanna. “It is exciting
to see the work of Josh, Dr. Moyer, and the other collaborators be published in
a peer-reviewed publication. Congratulations to them all.”
Grassi is the second student of Moyer’s to have his senior
research project published. The article of Grassi’s research article can be
