Professor of Biology

Teaching Area(s)

Biology / Environmental Studies


  • PhD, Environmental Science, Duke University
  • BS, Principia College


Dr. Greg Bruland's areas of expertise include natural resource management, soil science, soil and water conservation, wetland ecology, freshwater ecology, restoration ecology, statistics, watershed management, water quality, and diffuse reflectance spectroscopy. He currently serves as the math and natural sciences representative on the Committee for the Assessment of Student Learning (CASL), and has served as the chair of the College Curriculum Committee. Before joining the faculty at Principia College, Bruland served as an assistant and associate professor in the Natural Resources and Environmental Management Department at the University of Hawaiʻi at Mānoa (UHM). Prior to working at UHM, he was a post-doctoral research associate with the Soil and Water Science Department at the University of Florida.

"One of the reasons I enjoy teaching is that I continue to learn along with the students. Teaching is similar to parenting in that it is one of the most challenging but also most rewarding activities."


Bruland's scholarly interests are broad and collaborative, and they encompass multiple spatial scales from the micro (i.e., soil core) to the macro (i.e., watershed) levels. They span a range of related topics including soil and water conservation, watershed management, soil science, diffuse reflectance spectroscopy, geostatistics, wetland biogeochemistry, and coastal ecology.


Throughout his career Bruland has secured funding from various competitive federal agencies, published his research in numerous scholarly journals, taught many graduate and undergraduate courses at multiple institutions, and advised students at the PhD, MS, and undergraduate levels. Additionally, he has been a PI or co-PI for grants totaling over $2 million dollars. He has authored or co-authored more than 45 papers in the top peer-reviewed journals in his field, such as Proceedings of the National Academy of Sciences and Environmental Science and Technology. He has also given more than 100 presentations at national and international scientific meetings.

In 2021 Bruland was awarded the Horace Edwin Harper Jr. and Evelyn Wright Harper Award for Teaching Excellence.  In 2012 he was part of the Governor’s Award for Team of the Year along with other faculty and staff from the Natural Resources and Environmental Management Department at the University of Hawaiʻi at Mānoa.
