Yang worked as a lab and field technician at the University of California Berkeley from 2003-2004. She is currently an assistant professor of Plant Biology and Geology at the University of Illinois Urbana-Champaign. She is known for her work in soil biogeochemistry and ecosystem ecology, specifically examining the way nitrogen cycles through an ecosystem and the effects that anthropogenic use of nitrogen has on ecosystems. Her current research is focused on greenhouse gas emissions and soil and the role that microorganisms in the soil, like bacteria and fungi, have in producing these gases. She received a NSF grant to pursue this work in 2018, as part of a larger collaboration with scientists from Georgia Tech and the University of Tennessee Knoxville to understand the role microbes have in nitrous oxide emissions from soil.
Publications
Yang's most notable publications include her research on more precise methods for measuring nitrogen fluxes from terrestrial ecosystems, as it is often difficult to tell the amount of N2 gas released from soil due to the concentration of N2 gas already existing abundantly in the atmosphere. Another notable publication was Yang's research on leaf litter, how climate impacts the rate of leaf decomposition and the amount of nitrogen released by decomposition. Her most cited publications are as follows:

Personal life
Yang is married to Glen Yang and has two daughters. She enjoys baking desserts. One of her proudest achievements is crafting a cherpumple, a triple-layer dessert in which each layer is a whole pie.
