Created a historical topographic-bathymetric digital elevation model for the Sacramento - San Joaquin river delta to characterize the hydrodynamics of the delta under natural conditions. The "1850" elevation model represents the form and function of the delta prior to modifications of the geometry and hydrology.

Developed a family-level index of biotic integrity (IBI) to assess the response of benthic macroinvertebrate assemblages to anthropogenic disturbances using twelve years of continuous citizen-science monitoring. Trained volunteers to monitor water quality, assess stream physical habitat, and collect aquatic insects.
