Rose Abramoff
Rose Abramoff worked with the project as a postdoctoral fellow who studies the effect of global change on biogeochemical cycling in soils. Her work will synthesize field data into numerical models of soil organic matter decomposition and stabilization, focusing on mechanisms that determine the rate of SOM turnover, such as sorption of SOM to mineral surfaces and microbial activity. The ultimate goal of her work is to derive general principles of SOM turnover and apply these principles at the global scale using terrestrial biosphere models. She is participating in Task 4.
