Curriculum Vitae for Rick Routledge

This is a long page, so I've broken it down into sections:

Biography

I was born in 1948 near Aurora, Ontario. I studied at Queen's University (B.Sc.), University of Alberta at Edmonton (M.Sc.), and Dalhousie University (PhD, Biology). In 1980, I moved out West with my family to begin teaching at SFU. I still live in Port Coquitlam with my wife, Louise, and our dog, Tilly. Louise and I have two adult daughters: Laura designs organic cotton clothing in Vancouver, and Karen is a graduate student in New Jersey. The one thing that tempts me to retire is the possibility of more rock climbing road trips.

Michelle Franklin is working on the Juvenile Sockeye Feeding Biology project in the Fall of 2003. Tanya Bettles and Janice Brahney have both done work with the sediment coring project on the BC Central Coast.

 

Most Significant Publications:

1. Chiu, G., Lockhart, R., and Routledge, R. 2002. Bent-cable regression theory and applications. (Submitted to Journal of the American Statistical Association with requested revisions, Fall, 2002).
This paper provides statistical methodology for addressing a central question in research on threshold phenomena: Is there really a threshold at which an effect begins to develop, and if so, how abrupt is it? We demonstrate that in many applications where researchers have been tempted to draw definitive conclusions, there is insufficient evidence in the data to justify their claims. Richard Lockhart and I were Grace Chiu’s Ph. D. supervisors, and this paper was developed from part of her dissertation. A version of this paper won first prize in the 2002 Student Paper Competition conducted by the Western North American Region of the International Biometric Society.

2. Buchanan, S., Farrell, A. P., Fraser, J., Gallaugher, P., Joy, R., and Routledge, R. 2002. Reducing gillnet mortality of incidentally caught coho salmon. North American Journal of Fisheries Management, 22: 1270-1275.
This paper demonstrates the potential for dramatic reductions to the mortality rate for coho salmon caught incidentally by gillnets. The resuscitation box tested in the experiment described in this paper is now required for use in many British Columbia commercial fisheries. The research was recognized in 2002 with the Murray A. Newman Award for significant achievement in aquatic conservation and research. Ruth Joy and I performed the statistical analysis, and I took the lead in writing the article.

3. Routledge, R. D., and Irvine, J. R. 1999. Chance fluctuations and the survival of small salmon stocks. Canadian Journal of Fisheries and Aquatic Sciences, 56: 1512-1519.
This paper has had a unique, conservation impact. In it, we use Markov chains to predict local extinction probabilities for small salmon stocks, with direct application to many weakened coho populations. We show that the extinction probabilities are highly sensitive to environmental changes, and that they are potentially much greater than many people believe. The federal government has recently reaffirmed its commitment to preserving wild fish biodiversity with particular emphasis on coho salmon, and my co-author, a DFO biologist, has distributed it widely at public meetings. Jim Irvine provided the coho data and expertise on coho biology used for building the model. I built the model and performed the computations.

4. Routledge, R. D. 1997. P-values from randomization and F-tests. Computational Statistics and Data Analysis, 24: 379-386.
This paper demonstrates the closer agreement of mid-p-values vs. standard p-values in comparisons of conditional randomization tests against F-tests for the results of classic experimental designs. This has become an important practical issue as modern computers permit the calculation of p-values from randomization tests for increasingly larger and more complex experiments.

5. Chiu, G., Lockhart, R., and Routledge, R. 2002. Bent-cable asymptotics when the bend is missing. Statistics and Probability Letters, 59: 9-16.
This paper establishes the intractability of asymptotic distributions associated with a linear-quadratic-linear model when the quadratic portion is in fact absent. This somewhat surprising result shows that existing applications of the model have been in error. Richard Lockhart and I jointly supervised Grace Chiu’s Ph. D. research, and this paper was developed from part of her dissertation.
