Laurel received her B.A. in Biology from St. Olaf College and joined the Wallenstein lab in 2012. She studies how climate change impacts soil microbes and carbon chemistry in the Arctic. 


Substrate-induced priming in the Arctic
Northern circumpolar soils account for nearly half the estimated global organic carbon pool. This reservoir is critical to global carbon budgets as it exceeds the storage capacity of plants and sub-arctic soils combined and appears chemically vulnerable to decomposition as soils warm. The Arctic is experiencing unprecedented rates of regional warming, which may convert the Arctic from a net sink to net source of atmospheric carbon as soil organic matter decomposes. However, our ability to predict the response of global carbon cycling is limited by significant uncertainties in our understanding of alternative processes that may counteract or enhance soil organic matter loss. Our objective is to improve our mechanistic understanding of the effects of labile carbon inputs on Arctic tundra soils, which we predict will increase with greater shrub recruitment..
