Branch Chief (Hydrologic Studies)
CurrentSupervising the Hydrologic Studies unit in the USGS Pittsburgh field office [PA Water Science Center].Seven direct reports (6 hydrologists, 1 hydrotech) working on routine water quality monitoring across PA, the development of sediment-nutrient regression models for select watersheds and machine learning tools to predict groundwater levels, PFAS monitoring downstream of industrial sources and airfields, and assessing baseflow contributions to stream hydrographs. Serving as Project Chief for the Allegheny County Sanitary Authority's (ALCOSAN's) Consent Decree Water Quality Monitoring effort. This is a multi-million dollar project targeting 27 monitoring locations within the Ohio-Allegheny-Monongahela Rivers and their tributaries, studying water quality impacts of combined sewer overflows (CSO) during wet weather events, and changes in CSO water quality impacts post-infrastructure upgrades that ALCOSAN plans to complete in 2016. First round of sampling expected for September 2024.I continue to be a co-PI on my Reclamation studies as they wrap up this fiscal year. I also am a co-PI on two new studies! : 1) understanding variability in methane fluxes from Klamath River reservoirs during decommissioning, and 2) describing strontium isotope variability in San Joaquin Valley waterways as a function of human activity (ag discharges, reservoir ops) and understanding its implications when tracking anadromous fish migration.Reports Specialist for the Pennsylvania Water Science Center. I'm drafting guidance on document tracking within the center, ensuring that the process of document drafting and revision is standardized for all authors, ensuring that the process is easy to understand and that the rigorous USGS review process does not represent a stumbling block to providing our collaborators with critical information they need.
