Professional Registration:

Professional Engineer, P. E., Oregon #48590, Civil Engineering

Expertise:

• Water Quality and Hydrodynamic Modeling

• Development and application of CE-QUAL-W2 water quality model

• Ground Water Modeling

• Computer Programming

• Water Quality Sampling

• Environmental Data Analysis

Work Experience:

Research Associate (2001 to present) and Research Assistant (1997 to 2001), Portland State University.

Currently participating in the development of CE-QUAL-W2 water quality models. Responsibilities include computer programming, model calibration, water quality sampling, analysis of management scenarios, and the development of specialized macrophyte and culvert simulation algorithms. Contributed to the development of water quality models of the Tualatin River, Oregon; Columbia Slough, Oregon; Willamette River, Oregon; Lake Whatcom, Washington; Cooper Creek Reservoir, Oregon; Spokane River, Washington; Lake Whatcom, Washington; Laurance Lake, Oregon; and the Snake River, Idaho.

Consultant, Snake River Project (1997 to present). Participating in the development of a water quality and hydrodynamic model of the lower Snake River, Brownlee Reservoir, Hells Canyon Reservoir, and Oxbow Reservoir. Responsibilities include model development, calibration and alternative analysis.

Consultant, Wahiawa Reservoir Project (1996-1997). Helped develop a CE-QUAL-W2 water quality and hydrodynamic model of Wahiawa Reservoir, Hawaii. The model was used to evaluate alternatives designed to alleviate water quality problems caused by eutrophic conditions.

Contract Student Worker. U. S. Army Corps of Engineers Waterways Experiment Station, Vicksburg, Mississippi (October, 1996 to December, 1996). Conducted literature review of biological and chemical rate coefficients used in water quality modeling.

Graduate Research Assistant for Shuguang Li, St. Johns Landfill Project, Portland State University.

(December, 1993 to January, 1995). Developed groundwater flow model of Portland's St. Johns Landfill.

Graduate Research Assistant to Scott Wells, Tualatin River Project, Portland State University. (January, 1992 to December, 1995). Participated in the development, calibration, and implementation of CE-QUAL-W2 Tualatin River water quality and hydrodynamic model. Responsibilities included: preparation of channel geometry, inflow, and withdrawal information; development of a diversion dam algorithm; surveying of the river channel and gaging sites; model calibration and verification; analysis of management alternatives.

Junior Engineer. Mackenzie Engineering Incorporated, Portland (June, 1991 to December, 1991). Site development work including the design of storm sewers, sanitary sewers, roads, parking lots, and water utilities.

Assistant Watermaster. Tualatin River District, Washington County. Oregon (June, 1990 to September, 1990). Measured stream flows, maintained stream gaging stations, helped regulate water rights, surveyed stream gaging sites, and inspected wells in the Tualatin River basin.
