RECENT WORK EXPERIENCE
- Research Assistant, Durham Children’s Data Center (DCDC), Duke University (Jan 2017 – July 2017)
- Analyzed data from Durham County Social Services for DCDC and my dissertation.
- Data Scientist (Part-time), TransLoc, Durham (September 2016 - December 2016)
- Helped refine the multitudes of metrics available to the product team into understandable, actionable information, working exclusively in R. Favorite packages: flexdashboard, DT, highcharter, and the tidyverse (dplyr, readr, tidyr, etc)
- Data Science Intern, TransLoc, Durham (May 2016 - August 2016)
- Helped develop products and packages that simplify working with and understanding transit data. Also learning/experimenting with implementing the “agile” development philosophy but for data science.
- Research Assistant, Duke-UNC BECR Center, Duke University (Jan 2015 – May 2016)
- Investigated food purchasing behavior, food-related health outcomes, and food assistance policy (SNAP/WIC). The aim was to uncover trends that can help BECR design behavioral nudges to improve food choices. Also helped write papers/proposals and providing analytical results (graphics, tables, etc).
- Teaching Assistant, Sanford School of Public Policy, Duke University (Spring 2015)
- Co-taught PubPol 590 Applied Big Data Science Energy Data Analytics and Policy with Dr. Matthew Harding. Students learned introductory theory about causal inference (taught by Harding) and how to use Python to analyze large datasets and do basic econometric modeling and machine learning (taught by me). The goal was for students to finish the class with the capacity to do basic consulting for energy companies.
CURRENT RESEARCH PROJECTS
- “An Evaluation of the Double Up Food Bucks Program” (Main Chapter)
- I Investigate the effectiveness of a targeted fruit and vegetable subsidy as policy for improving the consumption habits of SNAP beneficiaries.}
- “The Purchasing Behavior of SNAP Shoppers: A Comparison Using Transaction Data”
- I describe and compare the purchasing behavior of SNAP vs non-SNAP shoppers using 3 years of grocery store transactions linked to loyalty card numbers.
- “Nudging Convenience Store Shoppers Towards Healthier Snacks” (UNC-Duke BECR Center)
- We test different healthful food nudges—shelf placement, messaging, bundling—across to a large set of local convenience stores.}
- “Understanding the Statistical Properties of IRI Store-based and House-based Scanner Data” with Matthew Harding and Ya Xue (USDA Grant)
- Analysis of food scanner data the USDA purchased from IRI. The goals of the grant can be broadly categorized into assessing the suitability of the IRI for nutrition policy research and comparing the IRI data to other publicly available data sets.
