Dr. Patricia Heiser

Patricia HeiserAssociate Professor of Earth Science
Phone: 406-447-4341
Ph.D. University of Alaska Fairbanks
B.S. University of Vermont
Areas of Interest:
Geomorphology, Paleoclimate, Landscape Dynamics
Courses Taught:
Environmental Science, Earth Science, Geomorphology, Field Methods, Research Methods
Dr. Heiser completed her undergraduate degree in geology and ecology at the University of Vermont and was soon off to Alaska to pursue her Ph.D. in earth science. Her graduate work focused on the glacial and sea-level history of the Bering Straight and included research in both Russia and Alaska. During a post-doc position at the University of Madison Wisconsin, she studied the permafrost features of northern Wisconsin. Her first teaching position was at Ohio University Athens where she taught geology, geomorphology, soil science and climate change. She was soon drawn back to Alaska and began a joint position with the University of Alaska Anchorage teaching geology and integrated science programs for education majors. She then moved on to the University of Alaska Fairbanks to help develop a geography program and continue research on paleoecology, lake system history, and tundra-forest ecotone dynamics in Southwestern Alaska. We are now lucky to have her at Carroll College as the Director of the Environmental Program. Her teaching in earth and environmental science is well loved by students and she continues to involve students in field research ranging from forest fire history using dendrochronology techniques to paleoecology using lake sediment cores. She loves skiing, hiking and about any activity outdoors.

Dr. Grant Hokit

Dr. Grant HokitAssociate Professor of Biology
Phone: 406-447-4460
Ph.D. Oregon State University,
B.S. Colorado State University
Areas of Interest:
Ecology, Conservation Biology, Herpetology
Courses Taught:
Biological Principles, Ecology, Comparative Anatomy

After completing his B.S. in Wildlife Biology at Colorado State University, Dr. Hokit worked as a park ranger for 4 years for the U.S. National Park Service. Returning to graduate school, he completed a Ph.D. in Zoology at Oregon State University studying the behavioral and population ecology of amphibians in the Pacific Northwest including a 4-year study on population declines. A two-year post-doc at the University of Florida examined the effects of landscape structure on the demography of populations of reptiles and amphibians. He has been a biology professor at Carroll College for the past 20 years. While at Carroll, his research has mainly focused on distribution patterns of amphibians and reptiles from Alaska, to Montana, to Ecuador. More recently, he is studying infectious disease ecology in an effort to construct an infection risk model for West Nile Virus in Montana. He has published over 30 peer-reviewed articles. He loves biking, hiking, skiing and long megatransects in remote regions around the world.

Dr. Lauri Travis

Assistant Professor of Sociology and Anthropology
(406) 447-4420
Ph.D. University of Utah
B.A., M.A. Colorado State University
Courses Taught:
Cultural Anthropology, Introduction to Native American Studies, North American Archaeology, Physical Anthropology, Archaeological Field School, Human Ecology and Environmental Impact Assessment.

Dr. Travis’ dissertation focused on Fremont subsistence and settlement patterns in the Great Basin. She has worked as a consultant in Cultural Resource Management for 30 years and conducted research in the western United States, England, Germany, Sardinia, Italy and Belgium. Her research concentrates on Intermountain archaeology, evolutionary ecology, paleoenvironments, and prehistoric subsistence. Her current research focus is paleoenvironmental change and human adaptation in the Big Belt Mountains in central Montana.
