Welcome to Dr. Weinman's Research Program!
Are you interested in Earth or Environmental Science? Work in this Dr. Weinman's lab focuses on trying to understand how landforms physically co-evolve with their chemistries.
For example, in the populous and developing regions of Asia, students are using optical luminescence (OSL) dating to test whether landform histories can explain why wells located only a few meters apart can have order of magnitude differences in dissolved arsenic.
Local soils being sourced on hillslopes in the nearby Sierra Nevadas, OSL and geochemical mass balance models are used to figure out the rates at which elements like arsenic are biogeochemically weathering.
Our overall goal is to use these weathering rates to see how land-evolution and surface-processes contribute to soil and aquifer quality and sustainability.
