Created SamPlan, a quality-controlled statistical toolkit for safeguards, comprising a fully functional prototype, documentation, automated testing, and user test procedures.Developed safeguards-specific uncertainty quantification algorithms, including - advanced uncertainty quantification techniques, - sample size calculation algorithms to minimize inspection effort while maintaining high detection probability, and - efficient calculation of worst-case scenarios of diversion from multiple material types.Served as Business Team Assistant Lead for the STEPS software project, with responsibilities including - planning a multi-phase adoption strategy to minimize developer effort, redundant user testing, and risk of production disruption; - writing use cases and developing functional prototypes for two modules; - updating SQL scripts to interface with new MS SQL database; and - testing software, including formal user testing and automated extraction of verification tests from legacy calculations.Facilitated the adoption of R for a section of approximately 25 analysts by - creating a tailored training course and - creating and maintaining tailored R packages. Conducted non-routine statistical analysis of verification measurement calibration to provide feedback to inspectors.

Oak Ridge, Tn

Developed methods, implemented software, and published results for radiation transport and data analysis codes ADVANTG, INVERSE, and Exnihilo.

Ann Arbor, Mi

Student researching inverse radiation transport methods.Developed uncertainty quantification methods for quantitative imaging, including– validation of fast-neutron coded aperture simulations,– propagation of counting statistics through the reconstruction operator, and– extrema-seeking methods for underdetermined reconstruction problems.Evaluated reactor-analysis applications for correlated sampling Monte Carlo radiationtransport.

Oak Ridge, Tn

Updated the ADVANTG code package in preparation for RSICC release.– Moved computationally intensive calculations into Python-accessible C++ modules via SWIG.– Developed a new approach for generating biased sources for MCNP5Applied ADVANTG to a wide range of problems, including:– Source/detector problems of interest to the Defense Nuclear Nonproliferation Research and Development Office (NA-22).– Dosimetry models for low-level waste generated by the High Flux Isotope Reactor (HFIR).– Shielding-configuration models for conceptual spent fuel repositories.Developed methodology for comparing worker exposures among used nuclear fuel disposition scenarios.
