My research revolves primarily around two broad objectives: 1. To examine the perceptual and cognitive skills involved in Major League Baseball (MLB) umpire ball--strike judgments and decisions, and 2. To develop statistical methodologies and computing processes for analyzing and visualizing MLB pitch-level data.

I have a website/blog at I also maintain several GitHub repositories at where you can find additional resources such as journal articles, presentations, et al.  

I'm originally from Levelland, TX. There's even a not-so-flattering song about my hometown. My wife, Lisa R. Baggett, M.D. is an anesthesiologist in the Baylor Scott & White Hospital system. We have a daughter named Rhett Elisabeth, born in December 2013 and a son named Keller Ellis, born in April 2016. In my free time I enjoy conventional and fly fishing, smoking meat in my custom off-set smoker, listening to My Morning Jacket, and following the Miserable Men of Instagram.

Tools I Use
RStudio is a powerful and productive user interface for the free, open-source, statistical and data visualization software application R.
ggplot2 is an add-on package for R which generates dynamic and elegant, publication-ready graphics.
dplyr is another add-on package for R which makes manipulating data frames and customizing output super easy.
Pronounced "Lah--Tek", LaTeX is a free, open-source document and scientific publication markup application.
