EXPERIENCE NARRATIVE

Dr. Stevens has over 30 years of experience in applying quantitative methods to issues arising in the

environmental, biological, and physical sciences, and over 10 years management experience. Areas of

expertise include design and analysis of complex, multi-objective environmental monitoring programs;

environmental statistics; sample surveys; linear and log linear models; spatial statistics; time series and

stochastic simulation. He was awarded the Distinguished Achievement Medal by the Section on

Statistics and the Environment of the American Statistical Association (ASA) in 1999, and elected a fellow

of ASA in 2008.

Dr. Stevens has broad experience in applying statistics to problems arising in the physical and biological

sciences. For over ten years, he was engaged in developing the statistical sampling theory supporting

the USEPA’s Environmental Monitoring and Assessment Programs spatially balanced probability

sampling, and simultaneously applying that theory to designing samples of a variety of aquatic

resources. He has a history of successful collaboration with both physical and biological scientists, with

joint publications with colleagues from disciplines such as aquatic ecology, wetland ecology, geography,

limnology, geochemistry, soil science, forestry, radiation biology, aerosol physics, and veterinary

medicine.

Dr. Stevens has supervisory and project management experience, both in academia and contract

research. While at Eastern Oregon State University, he was Area Coordinator for Mathematics and

Computer Science, and a Principal Investigator on a cooperative agreement from USEPA to develop the

sampling design for the Direct-Delayed Research Project. Subsequently, he has held positions as a

General Supervisor and Project Manager for two on-site contractors at the USEPA Laboratory in

Corvallis. In these roles, he supervised an interdisciplinary staff, and managed projects on spatial

sampling, development of indicators of forest health, ecoregion development, aquatic monitoring, and

development of condition indicators for lakes and streams.

In his position as Program Director, Program on Design and Models for Aquatic Resource Surveys

(DAMARS), he coordinated the research efforts of six faculty members, two post-doctoral fellows, and

five graduate students. One student completed a PhD dissertation under his direction, and he is

currently the major professor for a PhD candidate expected to finish in 2009, and the minor professor

for two PhD candidates in the College of Forestry. His active research interests are the use of ancillary

data in spatially-balanced sampling design, optimal spatial sampling design, and estimation and

description of regional trend from panel studies. He is also a consultant on environmental monitoring

design issues for the Warm Springs Indian Tribe, the National Parks Services Great Lakes Monitoring

Network, the San Francisco Estuary Regional Monitoring Program, California’s Surface Waters Ambient

Monitoring Program, California’s Fish Mercury Program, the Oregon Department of Fish and Wildlife,
