Professional Experience:

(1) Scientist, USDA Forest Service, Pacific Southwest Station, Berkeley, CA. 1967-1996

(2) 1982-90: Lead scientist and project leader, Improved Technology for Integrated Management of Western Forest Project (PSW-2203), USDA Forest Service, Pacific Southwest Station, Berkeley, CA. Designed and developed experiments to provide data for models simulating the effects of IPM strategies used for western spruce budworm and Douglas- tussock moth. Investigated physiological factors responsible for co-evolution of mountain pine beetle and western pine beetle and their host tree species. Designed statistical studies to ensure a firm basis for the construction and validation of simulation or prediction models for management strategies. Began development of population toxicology (now called eco-toxicology) as a means to estimate effects of chemicals in the field, based on results of laboratory data. Continued investigations of response to multiple explanatory variables.

(3) 1990 - 1998: Project Leader and Senior Scientist, Insect Genetics, Biochemistry, and Biometry Project (PSW-2206), US Forest Service (Pacific Southwest Station, Albany, CA). Designed and developed basic studies of biochemical and genetic indicators of forest insect population status, interactions of bark beetles and defoliators with tree species, and effects of secondary plant chemicals on success of infestation. Participated in use of molecular-genetic methods to trace points of entry of Tomicus piniperda into the US; initiated world-wide collections of this exotic bark beetle to identify point(s) of origin. Initiated development of statistical definition of chemical resistance; this investigation was essential to avoid confounding factors such as natural variation in response for resistance to a given chemical. With collaborators, continued development of ecotoxicology as a specialty area.

(4) 1997- present. As entomologist for LeOra Software, continued development of user-friendly computer programs for biologists whose data are collected in bioassays with one or more explanatory variables. These programs include PoloPlus, PoloDose, PoloMix, and PoloEncore. PoloPlus computes probit (or logit) quantal regression analyses and conducts automatic tests 4

of the hypotheses of parallelism and equality. Several features enhance the program’s use in toxicological and pharmaceutical testing. First, lethal dose ratios are estimated for statistical comparison of each preparation with a standard. Second, standardized residuals are calculated. Third, residuals are displayed in plots for identification of sources of lack-of-fit to the probit or logit model. Fourth, a fitted response curve for each preparation can be plotted. Finally, a Probit 9 (LD 99.9968) can be estimated to meet the requirements of the United States Department of Agriculture and regulatory agencies of other nations. PoloEncore extends the methods of PoloPlus to binary response models with multiple explanatory variables. Such models are rather common in bioassays with chemicals such as pesticides and pharmaceuticals. They provide an efficient means to use a single experiment to test the significance of more than one variable (such as dose) on response. PoloMix uses a chi-square statistic to test the hypothesis of independent joint action. This test is done by obtaining an estimate for the probability of mortality p for several dose or concentration levels of the two components and then comparing the estimate of p with the observed proportion killed at the corresponding dose levels. The three contributions to p are estimated separately. First, p0 is calculated as the proportional mortality observed in the control group. Next, p1 and p2 are estimated from bioassays of component 1 and component 2, with data analyzed with PoloPlus. The chi-square test statistic is then calculated. Finally, PoloDose is a designed specifically for the study of dose placement and sample size for any dose that would cause mortality greater than zero and less than 100%. PoloDose calculates the length of the confidence interval for µ0, the dose level that produces a certain probability of response P0, where 0

(5) 2001-2007. Completed revision of Bioassays with . This second edition was described by one reviewer as the most humorous statistical textbook ever written. In a recent review in 5

The Journal of Economic Entomology, Dr. Denny Bruck puts it this way: “In the preface, Jacqueline L. Robertson outlines the authors’ desire to write a textbook that enhances readability and keeps readers interested in the subject matter. Mission accomplished!” The third edition of this book (starring the same cast and whoever else I dream up) will be completed when the PoloTime computer program will be finished by 2013.
