• Ph.D. in Statistics with Designated Emphasis in Computational Science and Engineering.• Dissertation title - Subsemble: A Flexible Subset Ensemble Prediction Method.• Research focused on the development and application of statistical methods for causal inference, estimation, and prediction with longitudinal and large-scale datasets.• Projects included techniques for estimation and inference in the presence of interval-censored outcomes, scalable prediction algorithms for massive datasets.

• Developed novel statistical methods to analyze multi-cohort observational longitudinal data.• Translated quantitative methods and results into non-technical terms for scientist collaborators.

• Developed new techniques which improved the performance of Neustar’s IP geolocation prediction algorithm. • Evaluated algorithm performance using large-scale datasets and parallel distributed computational resources.

• Improved data quality and prediction performance by analyzing national agricultural surveys and censuses.• Discovered previously unknown data errors, diagnosed bias in record updating practices, determined more effective prediction variables for quantities of interest.• Created and presented an R programming tutorial for agricultural statisticians from the country of Georgia.

• Conducted original research on problems in probability, statistics, combinatorics.

• Taught courses in Probability & Statistics, Linear Algebra & Differential Equations.• Led sections, graded homework and exams, held office hours, conducted review sessions.
