Current Research and Scholarly Interests

Humanity is performing a vast, global-scale experiment with the earth, with significant effects on the oceans. Biogeochemistry is a multifaceted tool kit to provide useful contributions to the collective understanding of these changes. As a PhD student in the Stanford Department of Earth System Science, I study biogeochemical nitrogen cycling, with a focus on nitrous oxide cycling in oxygen minimum zones. My research uses a combination of fieldwork, analytical techniques, and computational methods such as vertical modeling to delve into nitrous oxide cycling in places of disproportionally high production — notably, the oxygen minimum zone in the eastern tropical North Pacific Ocean (ETNP). As oxygen minimum zones expand, I will explore how these changes affect nitrogen cycling, and the production and fluxes of nitrous oxide.

  • Quantitative drinking water arsenic concentrations in field environments using mobile phone photometry of field kits SCIENCE OF THE TOTAL ENVIRONMENT Haque, E., Mailloux, B. J., de Wolff, D., Gilioli, S., Kelly, C., Ahmed, E., Small, C., Ahmed, K., van Geen, A., Bostick, B. C. 2018; 618: 579–85


    Arsenic (As) groundwater contamination is common yet spatially heterogeneous within most environments. It is therefore necessary to measure As concentrations to determine whether a water source is safe to drink. Measurement of As in the field involves using a test strip that changes color in the presence of As. These tests are relatively inexpensive, but results are subjective and provide binned categorical data rather than exact determinations of As concentration. The goal of this work was to determine if photos of field kit test strips taken on mobile phone cameras could be used to extract more precise, continuous As concentrations. As concentrations for 376 wells sampled from Araihazar, Bangladesh were analyzed using ICP-MS, field kit and the new mobile phone photo method. Results from the field and lab indicate that normalized RGB color data extracted from images were able to accurately predict As concentrations as measured by ICP-MS, achieving detection limits of 9.2μg/L, and 21.9μg/L for the lab and field respectively. Data analysis is most consistent in the laboratory, but can successfully be carried out offline following image analysis, or on the mobile phone using basic image analysis software. The accuracy of the field method was limited by variability in image saturation, and variation in the illumination spectrum (lighting) and camera response. This work indicates that mobile phone cameras can be used as an analytical tool for quantitative measures of As and could change how water samples are analyzed in the field more widely, and that modest improvements in the consistency of photographic image collection and processing could yield measurements that are both accurate and precise.
