I am a biogeochemist who focuses on nutrient cycling and climate change. I recently joined the Earth and Environmental Sciences Department at CSU East Bay in September 2016. I am from the Bay Area and studied as a postdoctoral scholar at UC Berkeley for 3 years before coming to CSU East Bay. My research focuses on how ecosystems interact with the atmosphere. For example, I am currently studying how wetland restoration in the Bay Area and Sacramento Delta can be used to mitigate climate change.
My teaching philosophy is to engage students with hands-on active learning. I emphasize group work and discussions in the classroom while providing as many opportunities as possible to get outside and collect data. I am always accepting students into my lab so please contact me if you want experience with biogeochemical measurements.
I am particularly interested in minimizing the negative impact of managed lands on climate, water, and air quality. My expertise is in greenhouse gas and reactive trace gas emissions from diverse ecosystems including restored wetlands and agricultural land. I employ field monitoring and manipulation techniques in addition to process-based biogeochemical modeling with an emphasis on model-data fusion approaches. I collaborate with regional to global-scale modeling projects and am actively incorporating models into carbon policies in California.
