I have engaged with research and outreach projects at Biosphere 2 since I was an undergraduate student in Dept. of Chemical and Environmental Engineering at UA. With desires of understanding soil genesis and environmental sustainability of ecosystem, I joined Biogeochemistry group to work with Dr. Jon Chorover in Dept. of Soil, Water and Environmental Science at UA. My research/outreach interests are 1). Understanding geochemical transformations in controlled heterogeneous soil lysimeter (e.g. Landscape Evolution Observatory, LEO) and provide insights for natural field systems (e.g. Critical Zone Observatory, CZO); 2). Utilizing LEO to couple hydrological, microbiological and geochemical findings to develop advanced tools and methods to study Earth-system dynamics. 3). Delivering simplified scientific findings to general public and K-12 students.
