Dr. Gil Pontius specializes in geographic information science, quantitative modeling, spatial statistics, ecological sustainability and international development. He earned a Master of Applied Statistics from The Ohio State University and a PhD from the State University of New York's College of Environmental Science and Forestry. He has worked as a researcher in the private sector, as a statistician in the public sector, as a teacher in several universities, and as a Peace Corps volunteer in Tanzania. Most of his research focuses on land-use change and its effects on environmental issues such as climate change, biodiversity loss, and nutrient disturbance. Another aspect of his work serves the city of Worcester and local environmental organizations. He involves Clark University students in all his research. Courses he offers include
Courses Offered
Geog 110 Introduction to Computer & Quantitative Methods in Geography
Geog 260 Quantitative Modeling
Geog 391-394 GIS for Development and Environment
IDND 299 Human Environment Regional Observatory (HERO) Seminar
Current Research
1. NSF-funded Human Environment Regional Observatory (HERO) program to examine human-environment relationships in Central Massachusetts.
2. NSF-funded research to model how economic activity affects land-use change and hence nutrient flows in the Long Term Ecological Research site in Plum Island Estuary, Massachusetts.
3. Development and use of Geomod to simulate land-use change worldwide in order to examine how deforestation influences environmental health.
4. Techniques to measure the effectiveness of conversation projects
5. Creation of statistical methods to compare maps for remote sensing and model validation.
