Biography

 

INTEGRATES physics with biology, and numerical models with field observations, to understand how aquatic ecosystems work

COLLABORATES and LEADS scientists of multiple disciplines to implement a whole-ecosystem approach for understanding how a complex coastal system may respond to changes in climate, management and infrastructure over this century

  • Applies engineering training to study how environmental physics interacts with water quality and aquatic biology
  • Thinks of herself as an "Ecohydrodynamicist", but some of her friends call her things like "Hydro-phydamicist" (which she doesn't mind). 
  • Uses numerical models and field observations to link hydrodynamics to water quality and ecological processes
  • Focus is largely on tidal systems, though some work applies generally to rivers and lakes
  • Co-leads CASCaDE II, a hyper-disciplinary project of 30+ scientists linking multiple state-of-the-art computer models to assess plausible futures for the San Francisco Bay-Delta ecosystem over this century http://cascade.wr.usgs.gov/  (2009-present)
    • Assessing SF Bay-Delta ecosystem response to climate change, water management, and catastrophic levee breaks
    • Model domains span the atmosphere, Sierra-Nevada watershed, San Francisco Bay-Delta, and coastal ocean
    • Models reaching from "climate to the clams" (and also including watershed hydrology, sediment transport, hydrodynamics, phytoplankton, marsh, contaminants, and fish)
  • Loves being a member of Jim Cloern's Plankton Dynamics Team (http://sfbay.wr.usgs.gov/access/wqdata/)
  • Graduate work at Stanford University in the Environmental Fluid Mechanics Laboratory with Jeff Koseff and Stephen Monismith  (http://www.stanford.edu/group/efml/)
  • Undergrad alma mater is University of Notre Dame (the one in South Bend, Indiana)--GO IRISH!
