Professor (2015-present); Associate Professor (2009-2015); Assistant Professor (2003-2009), Santa Clara University, Santa Clara, CA.

Teach classes in hydraulics, water resources, hydrology, and Geographical Information Systems. Conduct a variety of research projects related to hydrologic modeling, predictability of runoff, and climate change effects on water resources. See other pages on this web site for details.

September 2002 - July 2003

Research Engineer/ Hydrologist, University of Washington, Seattle, WA.

With Prof. Cliff Mass in the Atmospheric Sciences Department, performed research related to hydrologic forecasting in the Pacific Northwest.

• Investigated the sensitivity of hydrologic model forecasts to representation and interpolation of orographic precipitation events in the Cascade mountain range. Developed and implemented an algorithm to use radar data for rain/snow determination.
• Refined a real-time flood forecast system for Puget Sound using mesoscale atmospheric model output and a distributed hydrologic model.

July 1998 - August 2002

Research Assistant, University of Washington, Seattle, WA.

With Prof. Dennis Lettenmaier performed research on macroscale hydrologic modeling.

• Investigation of sources of persistence and predicatability in the Mississippi River basin, including that due to soil moisture, snow, and climatic forcing, using a distributed hydrologic model.
• Comparison of the marginal improvement of different sources of observed and remotely-sensed snow cover on streamflow forecasts.
• Development of a system operation model for the Missouri River basin, including the major impoundments of the Corps of Engineers and the Bureau of Reclamation. This was used to test the sensitivity of reservoir operational decisions to changes in very long lead streamflow forecast skill.

Aug. 1994 - July 1998

Volunteer, Maryknoll Missioners, Peru.

• At the National University of the Altiplano (UNA) in Puno, Peru, assisted the Department of Civil Engineering. Taught a third-year hydrology course, helped establish a laboratory in hydraulics, and prepared proposals for international funding.
• With the NGO Caritas-Juli, responsible for projects of water development in the Peruvian altiplano near Lake Titicaca. Projects included hand-dug and drilled wells, gravity water systems for drinking water, and small-scale irrigation.
• At the Institute of Rural Education in Juli, Peru, performed a feasibility study for a micro-hydropower system and a small, gravity-fed sprinkler irrigation system as demonstration projects.

June 1990 - July 1994

Senior Engineer, Natural Resources Consulting Engineers, Berkeley, CA.

• Performed surface and groundwater analyses for feasibility-level studies for water rights determinations and water resources management on Indian Reservations throughout the western U.S. These included watershed-level hydrologic characterization, flood studies, studies on effects of watershed changes, historic, present, and future water requirement determination, studies of regional groundwater pumping plans, and salt-water intrusion.
• Responsible for hydraulic design for these feasibility studies, including canals, spillways, small dams, diversion structures, sedimentation structures, pumping stations, and pipe network designs.
• Computer modeling of hydrologic and hydraulic systems for watershed management, reservoir operations, pipe network optimization, sediment studies, contaminant transport, and groundwater pumping using customized programs and commercial software packages.
• Managed the Berkeley office of NRCE, which involved project management for budgeting and personnel, final report preparation and editing, coordination with clients, and preparation of proposals.

Sept. 1989 - May 1990

Research Assistant, Pacific Institute for Studies in Development, Environment, and Security. 

Conducted research sponsored by the Stockholm Environment Institute to develop a methodology for evaluating the effects of a rise in sea-level on coastal areas. Included analysis of coastal, estuary, and wetland effects, protection measures and costs, and a case study of the San Francisco Bay Area.

July 1988 - Aug. 1989

Research Assistant, University of California, Berkeley.

Conducted research with Prof. H.W. Shen involving mathematical and physical modeling of contaminant movement on a channel bed. Included laboratory experimentation of sediment intrusion into a gravel bed.

June 1985 - June 1988

Engineer, Kupper Associates, Piscataway, NJ

Designed gravity sewer and force mains and reviewed contractor's shop drawings during construction of pump stations and sewer systems. Performed feasibility and cost-effectiveness analyses of alternative wastewater systems for small communities, inventories of pollutant discharges to a river system, and cost estimates and budget analyses for wastewater facilities.

Sept. 1984 - May 1985

Research Assistant, University of Rhode Island, Kingston

Conducted research under Prof. Raymond Wright involving fate and transport of contaminants in the Pawcatuck River system in Rhode Island Participated in field data collection, laboratory analysis of samples, and computer simulations.
