Matthew G. Siebecker is an Assistant Professor of Applied Environmental Soil Chemistry in the Department of Plant and Soil Science within the College of Agricultural Sciences & Natural Resources at Texas Tech University. His research focuses on understanding soil chemical reactions and their implications for environmental contaminant mobility and remediation.
Dr. Siebecker received his educational background from:
- Ph.D. in Environmental Soil Chemistry from the University of Delaware (2014)
- B.S. with double majors in Environmental Science and Plant & Soil Sciences from the University of Massachusetts-Amherst (2006)
His research program centers on environmental soil chemistry with particular emphasis on the fundamental chemical reactions that control contaminant behavior in soil systems. Dr. Siebecker's work bridges molecular-scale understanding with field-scale environmental problems, especially those exacerbated by climate change. He employs advanced analytical techniques including synchrotron radiation to investigate heavy metal speciation and nutrient cycling in soils. His research group examines how coastal and inland contaminated soils respond to flooding events, with specific focus on elements like nickel, zinc, arsenic, chromium, phosphorus, and potassium.
Analysis of Dr. Siebecker's recent publications reveals strong trends in climate change impacts on soil contaminants, particularly how sea-level rise and extreme weather events affect arsenic mobility in coastal environments. His work also shows growing interest in sustainable agricultural practices, including novel fertilizer development and precision nutrient management. The technical approach consistently combines traditional soil chemistry methods with cutting-edge spectroscopic techniques to elucidate reaction mechanisms at molecular scales.
Dr. Siebecker teaches several key courses in the Plant and Soil Science curriculum:
- PSS 2330 - Urban Soils
- PSS 4330 - Environmental Soil Chemistry
- PSS 5330 - Advanced Environmental Soil Chemistry
- PSS 5336 - Soil Mineralogy
As leader of the Environmental Soil Chemistry Group at Texas Tech University, Dr. Siebecker maintains active research collaborations and utilizes advanced laboratory equipment including ICP-OES, X-ray diffraction systems, and microcosm setups that simulate field conditions. His work has significant implications for environmental remediation strategies and sustainable agricultural practices in the face of climate change.
