Professional Background

Since graduation from Michigan State University, I have been working in the testing industry for over 9 years. I started as a research scientist in the Assessment & Information group of Pearson, where I conducted research in support of test development and scoring for a variety of K-12 testing programs. My research focuses on applications of latent trait models to the analysis of ratings and computer-based testing.

In 2016, I started working at Pearson VUE, the professional testing group of Pearson. I worked as a lead pychometrician for the following licensure and certification testing programs, where my job mostly invovles test development, data analysis and modeling, and conducting job task analysis and standard setting workshops:

• National Council of Examiners for Engineering and Surveying (NCEES)
• National Association of Boards of Pharmacy (NABP)
• Board of Registered Polysomnographic Technologists (BRPT)
• National Strength and Conditioning Association (NSCA)

Experience in R

I have been using SAS for my daily work and have limited experience in R. I used R for some graduate classes before. I am learning now and hope to use it for future work.
