    • RECENT RESEARCH ACCOMPLISHMENTS
    My recent accomplishments fall into four categories: data, integrated use of models and data, model development, and scale issues. Questions addressed and results, significance, and impact are described below.

    1. How do hydraulic-conductivity measurements relate to the values required by models? How can they be used most effectively to constrain model development?
    2. How can sensitivity analysis and nonlinear regression best be combined with hydrogeologic data to constrain models of ground-water systems, thus increasing likely model accuracy? How can model uncertainty best be quantified and what purposes can uncertainty methods serve?
    3. Do available numerical methods and programs solve the forward problem well enough to support the sensitivity analysis, nonlinear regression, and uncertainty analysis methods of my own work and others? How can these deficiencies be remedied?
    4. How can scale issues be most advantageously addressed?
    5. Develop more effective ways to constrain ground-water models to enhance their accuracy.
