CASE STUDY
Visualizing COVID-19 testing outcomes
2020-2021
In the fall of 2021, I began working with a team of researchers at Idaho State University College of Pharmacy to assess how community-based pharmacies could best assist the Idaho Department of Health & Welfare's efforts to meet the need for convenient, accurate COVID-19 testing and education in the community. In addition to my role as Project Coordinator, I performed data analysis and created the visualizations the manuscript, published in the Journal of the American Pharmacists Association (JAPhA) on August 14, 2021.
CASE STUDY
Cannabis cultivation, processing, and retail. Driven by data.
In 2023, I had the good fortune to work with Pleasantrees Cannabis Company, a vertically-integrated cannabis cultivation, processing, retail, and wholesale operation.
