Meredith Greer This partnership formed at Bates College when Ella Livesay took Meredith Greer’s course on mathematical epidemiology. It continued through the writing of this article. And since Ella stayed in Maine post-graduation, as a consultant in health analytics, we are fortunate enough to celebrate in person that the article is appearing in Math Horizons. The authors thank Chip Ross and Karen Palin for close consultation and edits on drafts of this article.
