About Dr. Gregory G Brown

Greg joins Cal Poly as NRES Department Head in 2016 after serving in multiple academic leadership positions at the University of Queensland, Central Washington University, University of South Australia, Alaska Pacific University, and Green Mountain College. He has also held teaching and research positions in Idaho, Illinois, California, and Arizona.

Greg has taught and conducted research in the areas of environmental planning and policy, natural resource management, ecosystem services, parks and protected areas management, socio-economic assessment of rural communities, and public participation methods.  His current research involves methods to enhance and expand public involvement in environmental planning/management by integrating social spatial information using "Public Participation Geographic Information Systems" (PPGIS). His applications of PPGIS methods include forest planning, national park planning, assessment of ecosystem services, coastal areas planning, and urban parks and open space planning. Greg founded the Landscape Values and PPGIS Institute to facilitate global research and communication about participatory spatial planning methods. To learn more about PPGIS and landscape values mapping.

Student comments about the teacher:

The instructor is passionate about the course and provided a ton of cool resources (documentaries, readings, etc.) that showcase different aspects of environmental leadership.

This course generated many meaningful discussions. This was my first college course that I feel actually bettered me as a person. Greg clearly cared about us all and it fostered a wonderful environment. Truly a class I will always look back on fondly.

Very knowledgeable and passionate about the subject. He answered questions well and encouraged class debates.

1 Teaching quality rating is based on student teaching evaluations completed by Cal Poly students. A cumulative grand average for all courses taught over the last two years is calculated from responses to the student evaluation question, "Overall, this instructor was educationally effective" that ranges on a scale from 1=Strongly disagree to 5=Strongly agree.
