I have over 20 years experience in the fields of Computer Science, Physics, Mathematics, and Chemistry. Since 1998, I have been working on the Department of Energy's Atmospheric Radiation Measurement (ARM) Program as a value added products and data system developer and project manager working closely with atmospheric scientists to obtain a thorough understanding of the data management requirements within atmospheric sciences.

I have served as a group manager, project manager, system architect, and developer with experience in all aspects of project management (budget, schedule, resource, and risk analysis), architecture and system design, coding, testing, installation, and maintenance.
