Members of GeT: A Pencil have recently published in a diverse set of journals. Priya Prasad’s team wrote for The Mathematics Enthusiast, Orly Buchbinder coauthored a paper that appeared in JRME, and Tuyin An and her colleague presented at the Interdisciplinary STEM Teaching and Learning Conference. In the more mathematical realm, Michael Ruddy is awaiting the publication of his paper on linear Gaussian covariance models. Congratulations to everyone!
