My Research
My current research examines biogeochemical transformations at the land/ocean margin and at the sediment/water interface. My methods include using sediment bioreactors and in situ sampling alongside frequentist and Bayesian modeling approaches to monitor spatial and temporal environmental change. As a biogeochemist, my role is to investigate what is happening on a molecular level and translate the potential impacts at the ecosystem scale.
TraCing Terrestrial ORganic Matter
I collaborated as part an NSF RAPID project to investigate the sources and transport of terrestrial organic matter along a mountains-to-ocean transect following storm events. Read more about our findings here.
Sediments as a Source of Nutrients
I use nearshore marine sediments collected in the Santa Barbara Channel to investigate their potential to contribute nutrients to the overlying water column.

Consumer-Derived Nutrients
I participated in several projects designed to measure the excretion rates of various consumers and the impacts of this nutrient subsidy on the surrounding marine and terrestrial communities. Read more about our findings here.
Responses to Extreme WEather
Following the Thomas Fire and the resulting Montecito debris flow, I am analyzing the composition and transport of pyrogenic material and terrestrial debris deposited on a local beach.

Nutrient Cycling in Coastal Waters
By monitoring concentrations of inorganic nitrogen species in the water column and nitrogen content of frond tissue, I aim to clarify the patterns of availability of nutrients that support giant kelp growth.
