Active Research Fields

Earth science education

Earth Science Education Research focuses on understanding how people learn about the earth in classrooms, in laboratory settings, in the workplace, and in the field. It also focuses on the systematic study of how teaching Earth science can be improved in all of these settings. This kind of research uses methods drawn from the social sciences, such as laboratory experiments, interviews, surveys and classroom or field observations. Our research generates new theories about how people learn Earth science, new ways to measure skills and knowledge and rigorously tested new approaches to teaching. Our aim is simple: through this research we will improve student, teacher, and public understanding of the geosciences and ensure a broad, diverse and well-prepared future geoscience workforce.

Students in the Department of Geological and Environmental Sciences have the opportunity to earn an M.S. in geosciences focused on geoscience education. Through a partnership between the Department of Geological and Environmental Sciences and the Mallinson Institute for Science Education, WMU also offers a Ph.D. in science education with a geosciences emphasis. Furthermore, the Mallinson Institute for Science Education offers a unique concurrent enrollment program in which students earn both an M.S. in geosciences and a Ph.D. in science education. Graduates from these programs have attained positions in middle/high school teaching, community college teaching, administration, outreach and informal education, teaching-focused positions in universities and faculty research positions in geoscience departments.
  • Specific areas of research include: The role of spatial thinking skills in geologic fieldwork and hydrogeology; comparison of novice and expert approaches to solving geoscience problems; the role of fieldwork in undergraduate geoscience education; developing and testing new Earth science curricula and classroom approaches; and preparation and professional development of K-12 teachers.

Geochemistry

The Department of Geological and Environmental Sciences hosts an energetic and growing program of diverse geochemical research. Faculty explore a range of socially and scientifically relevant problems, employing modern techniques in both the laboratory and the field. Furthermore, we have pioneered an innovative undergraduate program in geochemistry, the only one of its kind in the nation. Students enrolled in this cutting-edge program gain access to a rigorous curriculum that cultivates expertise in a range of geochemical subjects that are in high demand throughout the environmental consulting, geotechnical and remediation fields.

  • Our geochemical research is essentially focused on: Biogeochemistry, geomicrobiology, isotope geoscience and low-temperature aqueous geochemistry.
  • Geochemical research facilities: Geochemical research facilities are primarily housed  in Haenicke Hall, built in 1997, integrating geoscience, biology and chemistry research laboratories that facilitate active cross-disciplinary research and collaboration. Additional research facilities are housed in Rood Hall.
  • Major instrumentation managed by geoscience faculty in Haenicke and Rood Halls includes: An ApplikonBio chemostated bioreactor; a Perkin Elmer Optima 2100 DV; a QuantaChrome Nova 2200 particle surface area analyzer; a Micromass Optima stable isotope mass spectrometer; two large Coy glove-box anaerobic chambers; UV-Vis spectrophotometers; a Dionex Ion Choromatograph; an SRI FID Gas Chromatograph; an X-ray diffractometer and a wide range of conventional laboratory equipment for routine geologic, wet chemical and microbiological work.
  • Field equipment includes: Field-portable UV-Vis spectrophotometers and chemical analysis equipment; pore water diffusion equilibrators for time-integrated groundwater sampling; a pore water squeezer and sediment coring equipment.

Geoinformatics and spatial data analysis

The Department of Geological and Environmental Sciences has developed a strong research emphasis in the areas of geoinformatics and spatial data analysis. Research in these fields is being enabled by a state-of-the-art remote sensing facility and a unique graduate certificate program in unoccupied aerial vehicles (UAVs).

Projects: Several ongoing projects address the potential influences of natural processes, global change and regional human activities on the water and carbon cycles and on ecosystems. Dr. Mohamed Sultan and his collaborators develop and apply an integrated systems approach to assess, monitor and model the recent and future impacts of changes in the landscape and land cover. Remote sensing and geographic information systems are being used to analyze and visualize spatial datasets to address a wide range of hydrologic and environmental problems.
