Biography
I am interested in earth science and ecology. I grew up in Oakland, California and in my free time like to surf, mountain bike, and ski. I have spent the last two summers backpacking along the John Muir Trail surveying impacted areas for restoration projects. I believe in the research of climate systems as a crucial means to better understand and mitigate the impacts of climate change.

Research
Wetlands have an extraordinary ability to purify waters and combat climate change by storing carbon. My work involves measuring water chemistry, soil chemistry, and gas fluxes, to study the biogeochemical processes in coastal wetland ecosystems. I deploy aquatic sondes in Elkhorn Slough channels to measure water chemistry such as conductivity, temperature, DO, fDOM, pH, ORP, algae, turbidity, and pCO₂. Using digestion, leaching, and spectrometry techniques, I analyze water and sediment’s nutrient and elemental composition, including heavy metals. Additionally, I assist with eddy covariance towers that integrate local variations in greenhouse gas fluxes with meteorologic data to quantify gas exchange in estuarine environments.
