The “small-watershed” ecology approach measures all precipitation chemistry (inputs) and stream solute fluxes (outputs) within a watershed. This has led to key environmental insights such as the discovery of acid rain. Currently, upwards of 150 different federally funded sites have implemented this watershed approach to evaluate site-specific questions about climate...
The goal of capstone project is to apply and extend custom analytics solutions to discover how life remains resilient in extreme environments. An explosion of data has resulted from recent discoveries of tiny single-celled life hiding out in the most extreme places on Earth. These single-celled creatures, or microbes, thrive...
Wild animals eaten by humans are known as “wild meat”, or “bushmeat” in sub-Saharan Africa. Hunting for bushmeat is both an ancient and modern practice, but as we step into the Anthropocene, bushmeat hunting has become unsustainable in many areas, threatening biodiversity and the food, financial, and cultural security of...

Machine learning models used in production settings are frequently retrained as new data becomes available to improve accuracy. However, this causes inconsistencies between the predictions provided by different versions of the model, a process known as prediction churn. This is undesirable for end users and organizations, as it might result...
Despite the availability of diverse geographical data, annotating it for analysis is time-consuming, requires specialist knowledge of the specific application domain, and existing supervised models based on domain-specific labeling have limited applicability. This expensive and time-consuming process results in unequal access to datasets, especially in low-income countries. To overcome these...
Climate change, particularly rising temperatures, is destabilizing the ecological balance within the Sargasso Sea and the Costa Rica Thermal Dome which are critical areas that require marine conservation measures. In this project, we observed both short- and long-term biological changes in these high-seas locations, detecting seasonal patterns and the consequences...
Systemic Lupus Erythematosus (SLE) patients are among the vulnerable groups of people facing increased COVID-19 vaccine hesitancy tied to socio-economic factors like barriers to healthcare access and lower household income. This project set out to identify socio-economic factors contributing to vaccine hesitancy among SLE patients and model their relationship to...
