About

Research Themes:

We explore the connection between terrestrial biogeochemistry and the Earth’s climate system. We focus on carbon cycling in wet environments spanning different human disturbance and management conditions, such as wetlands, temperate rainforests, and waste systems. We use a mix of methods to measure, understand, and predict biogeochemical processes, combining soil science, ecosystem ecology, and Earth systems science. In the laboratory, we manipulate soil conditions to understand the microscale controls of processes like decomposition and rates of greenhouse gas emissions. In the field, we make long-term measurements of gas exchanges to quantify the unique greenhouse gas signatures of wet ecosystems and how they respond to land-use and global change. At regional to global scales, we use data science and machine learning to synthesize big data from global scientific and sustainable development networks. Current collaborators include eddy covariance flux scientists from AmeriFlux (FLUXNET-CH4), an NSF-funded coastal rainforest margin’s research coordination network (CRMRCN), and SOIL, a research and development non-governmental organization providing sanitation services in Haiti.

EAES 494 Data Science and Statistics EAES (Fall 2021)

We in the Earth and Environmental Sciences (EaES) are feeling the effects of rapid technological change. In the last couple of decades, our ability to acquire long-term, continuous, and high-frequency environmental measurements – even in remote locations – has improved radically. These advances resolve old problems of data scarcity and present new opportunities to study the earth. However, to take full advantage of “big” data, we need to become better data scientists. This course will introduce you to fundamentals of coding in the free and widely used programming language ‘R’. Through hands-on classroom programming and interactive data analysis, you will become familiar with the data science workflow including how to import, tidy, visualize, analyze, and communicate big EaES datasets, including geospatial data, and how to use version control to ensure your work is reproducible, a valued skill in both private industry and academic research. The course will also cover fundamental statistics including data distributions, descriptive statistics, and linear regression. You will need access to a personal computer but there are no math or computer science (coding) prerequisites for this class.

EAES 579 Climate and Ecosystem Science (Spring 2022)

This course will explore contemporary global climate change using the knowledge and methods of ecosystem science. Students will study the biogeochemical regulation of the global climate system and will focus on important mechanisms organized across a hierarchy of scales (i.e., soil microbial, to vegetation canopy, to landscape patchwork, etc.). Course content includes lecture, laboratory experiments and/or field work, geospatial data analysis, reading of primary literature and select textbook chapters, group discussions, and oral presentations.
