Unlock critical insights into the delicate interactions between soil, water, and air and research new ways to preserve our natural resources.
Geoscience is the scientific study of Earth processes from an interdisciplinary perspective that combines perspectives from Geography, Geology, Biology, Ecology, Chemistry, and other disciplines. The Geoscience Ph.D. candidates refine their understanding of how humans are driving environmental change and helps them create research to solve problems to preserve biodiversity for future generations.

Why Earn a Geoscience Environmental Science Ph.D.?

The environmental science program is an interdisciplinary collaboration among the Department of Biological Sciences, the Department of Geography, the Department of Chemistry, the Department of Philosophy and Religion Studies and other departments at UNT to examine major environmental issues through an interdisciplinary perspective.

The program offers graduate studies in environmental science that lead to the PhD, granted through the Department of Biological Sciences. The course of study, involving both core and elective courses, is designed for those students who desire an interdisciplinary perspective concerning human-environmental interactions.

Marketable Skills
  • Communication to professional/lay audiences
  • Design field-based research protocols
  • Proficiency in environmental ethics
  • Recognition of national/international issues
  • Lead/direct research programs/projects

Geoscience Environmental Science Ph.D. Highlights

The rigorous curriculum has helped students receive prestigious appointments and awards from organizations including the Entomological Society of America.
The department’s facilities for research and graduate training occur in the Life Sciences Complex; Science Research Building; and the Environmental Education, Science and Technology Building.
The Life Sciences Complex, which has Gold-level Leadership in Energy and Environmental Design certification for sustainability, includes an aquatics laboratory and four climate-controlled rooftop research greenhouses.
Qualified students are supported through competitive teaching assistantships or research assistantships funded by research grants to faculty members. Nine-month stipends and tuition scholarships are available for entering master’s and doctoral students.
Our faculty members include internationally renowned researchers who have earned recognition from the National Science Foundation, the American Association for the Advancement of Science and the American Society for Microbiology, among others.

Geoscience Environmental Science Ph.D. Courses You Could Take

Remote Sensing (4 hrs)
Theoretical bases and practical aspects of digital remote sensing. Remote sensing technology is reviewed and data analysis techniques are presented. Approaches to the development of a remote sensing project are given. Hands-on experience is provided in the laboratory.
Soils Geomorphology (3 hrs)
Methods and applications of soils and landform analysis. Soils classification, formation processes and relationships to landforms and vegetation are stressed. Methods of soils description, mapping and physical-chemical analysis are taught, and applications to study of landscape changes and land-use planning are emphasized.
Global Environmental Change (3 hrs)
Explores current scientific and policy perspectives on key issues of global environmental change. Topics include climate change, land-use and land cover-change, terrestrial and ocean acidification, and water pollution. Critically examines scientific evidence for these phenomena and attendant consequences for Earth’s physical, chemical, and biological systems. Involves comparisons and assessments of policy responses.
Surface Water Hydrology (3 hrs)
Study of hydrological processes with emphasis on the hydrological cycle; soil moisture and infiltration; watersheds and drainage systems; flow mechanics, sediment transportation and deposition; and river response to climatic change and other impacts of human activity. Requires completion of an individual research project on a topic in surface water hydrology.
Introduction to Groundwater Hydrology (3 hrs)
Topics include principles of groundwater flow; aquifer properties and characteristics; geology of groundwater occurrence; groundwater development and methods of assessing and remediating ground water contamination. Students independently acquire, evaluate and interpret hydrogeological data and report the results in a research paper.
Environmental Modeling (3 hrs)
Modeling of environmental processes and human impacts on the environment to include topics on sensitivity, calibration and evaluation, watersheds, non-point source pollution, hydrological models, GIS, water and air quality models, pollutant transport and fate, and ecotoxicology.
