Honors & Publications


Achievements

  • Combined sales and cost data with measures of uncertainty, to guide clinical development planning.
  • Developed powerful SAS macros to produce a large number of standardized reports.
  • Interacted with clients to reduce redundant analyses, properly adjust for multiple comparisons, migrate from usage of pvalues to confidence intervals and measures of evidence.
  • Developed innovative and informative statistical analyses, to directly answer important scientific questions. In an intensely production-oriented work environment, orchestrated the transition of eight health data analysts and computer programmers from SPSS/Foxpro to SAS.
  • Established company-wide policy for hypothesis testing, statistical modeling, data cleaning and project computer directory structures.
  • Constructed statistical protocol and performed analysis for epidemiologic monitoring and quality improvement projects, to estimate and test for improvements in clinical processes and outcomes.
  • Introduced and applied important methods which corrected for secular trends and differences in distributions of prognostic factors. Drastically strengthened scientific rigor of study designs.
  • Using general linear models, showed how modifying ships' restocking procedures would improve post-refitting efficiency. The Navy followed recommendations and has been successfully filling material requisitions in significantly less time for ships after refitting.
  • Identified important trends in reasons corporate foundations give to higher education.
  • Pinpointed, using survival analysis techniques, the extent to which expediting efforts were quickening material delivery to deployed Navy ships.
  • Demonstrated statistically to the Virginia Department of Environmental Quality the satisfactory excavation and cleansing of a toxic waste site.
