Dr. George “Wolf” Gumerman 

Wolf Gumerman, Director of the University Honors Program and Professor of Anthropology at Northern Arizona University, is an archaeologist who applies his research to broader societal concerns, including collaborating with the Hopi Cultural Preservation Office to promote cultural preservation. Using archaeology and elder knowledge he connects Hopi youth with their past. The collaboration has produced four films and a museum exhibit that present the youth’s perspective on Hopi culture and history. Wolf also has a strong interest in food and culture stemming from his 20 years of research on the north coast of Peru and from his interest in sustainable food systems. He is Co-founder and past Co-editor for the Journal Heritage Management and publishes primarily on topics related to prehistoric foodways. Wolf teaches a range of interactive courses on composition and literature, archaeology, theory, human evolution, and food and culture.


Jacob Fillion, M.A.

Mr. Fillion has over 30 years of experience working in both the public and private sectors and has a Masters degree in Education from George Washington University.  He is currently the Environmental Education Branch Chief and International Programs Coordinator at Grand Canyon National Park where he has been since early 1998.  At Grand Canyon Jacob has developed an interdisciplinary environmental education program that reaches over 50,000 young people annually through on-site curriculum-based programs, Junior Ranger programs, overnight camps and distance learning programs.  Most recently he has begun developing international programs for Grand Canyon; he was instrumental in establishing Grand Canyon National Park’s first sister park – Yuntaishan World Geopark in China.  Prior to working with the Park Service he worked in Washington DC for 15 years, 10 years for the Peace Corps as the Environment Sector Specialist in the Office of Training and Program Support working on projects in Central and South America, Eastern and Central Europe, Africa and the Pacific Islands.  Jacob was a Peace Corps Volunteer in Paraguay from 1979 – 1982 as an agricultural extension agent.  In the private sector Mr. Fillion was the Director of Education and Programs at the Engineers and Surveyors Institute in northern Virginia and an instructional systems designer for a small consulting firm in Washington, DC.

Ted Martinez

Ted Martinez 


Ted Martinez holds degrees in botany and environmental science and policy from Northern Arizona University. In 2005 he moved to Yuma AZ to what is essentially the “end of the line” for the Colorado River before the US and Mexico take their allocations of water. In Yuma Ted has been able to utilize his education in botany and environmental science to perform conservation, education and restoration in the Lower Colorado River (LCR) Valley between the US and Mexico. There Ted has received grants from the Sonoran Joint Venture, Xerces Society and Arizona Game and Fish to perform wetland restoration, Monarch conservation and Bighorn Sheep education and outreach respectively.  Ted has also worked with Mexican partners, ProNatura, to perform bi-national wetland restoration along the Colorado River region dividing the US and Mexico. His recent experiences in the LCR have made him interested in the ability of humans to both negatively and positively impact the environment.  If humans can negatively impact their environment, then through massive effort can they also positively impact the environment? He also wonders if we can reconcile our role with the environment by changing our perception of nature as separate from humanity. Ted is happy to be in the NAU Honors Program teaching classes on plants, water and the environment. 



Dr. Thomas D. Sisk 

Tom Sisk, the Charles Olajos and Ted Goslow Endowed Chair of Environmental Science and Policy for the Southwest is an ecologist whose work focuses on three interrelated goals: improving our understanding of ongoing environmental change; engaging others in the challenges, societal relevance, and rewards of conservation; and helping to provide solutions to emerging problems facing policy makers and land managers. Tom has worked around the world developing a broad perspective on science, government, and the environment. His experiences provide insight into the relationship between science and management, as well as the challenges associated with translating sound science and progressive policy into on-the-ground action. Sisk’s laboratory group researches a broad range of topics related to the restoration and conservation of biodiversity and sensitive habitats, combining field study, geographic analysis, and spatial modeling. Tom’s courses in conservation biology, landscape ecology, and environmental policy and leadership emphasize theory in the natural and social sciences, and grounds student experience in field study and real-world applications. Tom serves on numerous advisory and editorial boards and is a certified Senior Ecologist of the Ecological Society of America and an Aldo Leopold Leadership Fellow.

Stephanie Sutton, MS

Stephanie Sutton is a District Interpreter and the Canyon Field Schools Director at Grand Canyon National Park. She has an undergraduate and graduate degree in Environmental Studies and completed her master’s thesis on the value of citizen science in raising science literacy among English language learners. She has a strong passion for education and science and a keen interest in connecting individuals with natural landscapes. She has dedicated her professional life to developing unique opportunities for raising science literacy among visitors and students alike. Currently, Stephanie is developing a plant phenological monitoring program to increase understanding of the impacts of climate change in Grand Canyon and she is expanding the scope of interpretive and education programming to incorporate hands-on science education/citizen science. Stephanie believes that the future of conservation lies with an interested and informed public and through the Grand Canyon Semester hopes to inspire students seeking professional and personal growth in science education.
