Ph.D., Forest Soils, University of Wisconsin-Madison
M.S., Soil Science, University of New Hampshire
B.S., Forest Engineering, University of Maine at Orono

Samantha, a native of Kittery, received a B.S. in forest engineering from the University of Maine-Orono in 1987. She then continued work as an on-the-ground forest industry professional that she began as an intern with Scott Paper Co. during college.

When she attended graduate school at the University of New Hampshire, she discovered an affinity for teaching and scholarship and an interest in soil science.

After completing an M.S. in soils at UNH, Samantha traveled to the University of Wisconsin-Madison to earn her Ph.D. in soil science, awarded in 1995.

Sam has been on the faculty of the Department of Environmental Science since 1996. As of 2010, Sam is Associate Vice President for Academic Affairs for Research, Scholarship, and Creative Activity.
