Specialty Areas of Interest:

Environmental Science, Soil and Water Chemistry, Geochemistry, Biogeochemistry, Geomicrobiology

• Identify the biogeochemical processes involved on sediment-contaminant transport from different land use and their effects on the water quality of rivers, lakes, and ground water
• Investigate how the physico-chemical characteristics of soils (soil organic matter, oxide minerals, clay minerals, porosity, hydraulic conductivity, etc.) influence the transport and fate of contaminants and nutrients
• Investigate the role of bacteria on pesticide persistence and degradation in low temperature systems
• Examine correlations between inorganic and/or organic contaminants co-transport with dissolved organic matter (DOM) and particulate organic matter (POM) spatially and temporally in river systems

Research opportunities exist in Dr. Vázquez-Ortega’s group for highly motivated undergraduate and graduate students who are interested in pursuing a B.S. (Geology: Environmental Science), M.S. (Geology) or Ph.D. (through Biology department) degree. Financial support such as teaching and research assistantships will be available for top candidates. For more information, please contact Dr. Vázquez-Ortega.
