I am a hydrogeochemist with additional expertise in data sciences driven by a research interest in the interface between humankind and the water cycle. I use field-based and geochemical laboratory-based approaches (e.g., noble gases, stable isotopes, and water chemistry) to shed light on the environmental implications of human activities on water resources. I also develop and apply data mining algorithms to explore the spatiotemporal patterns of water quantity and quality in the coupled natural and human system. I am particularly interested in water sustainability and the connection between energy/agriculture/urbanization and water quality.
My group uses noble gas, hydrogeochemistry, and data science tools to study the water cycle in the coupled natural and human systems over a broad range of temporal and spatial scales. Field geology, state-of-the-art geochemical analyses, as well as emerging data mining (big data) tools are blended in our work. Students in my group have the opportunity to incorporate one or more of these elements in their projects.
In teaching, I constantly strive to incorporate data science modules in the geoscience courses, e.g., Hydrogeology and Aqueous Chemistry. These updated courses will prepare SU students to address environmental challenges in the coupled human and natural Earth system as well as in the era of Big Data.
Students interested in graduate study are encouraged to contact Prof. Wen before applying to further inquire about the opportunities available. Please include a brief description of any prior research activities (note: prior research experience is not required for admission!) and your current research and educational interests. Interested students can check this departmental website for the admission requirements.
Students interested in conducting research in the Hydrogeochemistry And eNvironmental Data Sciences (HANDS) group should contact Prof. Wen.
