Since 1874, AAAS, a scientific society aimed at advancing science, engineering, and innovation “throughout the world for the benefit of all,” has annually named a class of fellows. This year, the work spans 24 scientific disciplines.
Brian D. Gregory is professor of biology and graduate chair in the School of Arts & Sciences’ Department of Biology. Gregory has pioneered the development and use of high-throughput sequencing and computational biology approaches to study the structure, modification, and interactions of ribonucleic acid (RNA), primarily working in plants. Elucidating the dynamics of RNA, Gregory’s studies have highlighted previously unappreciated regulatory processes that affect how genes are expressed or silenced. His insights into RNA regulation have important implications in plant biology but also extend to understanding gene regulation in other species, including humans. Training students to employ new genetic and computational technologies is a focus for Gregory, who has mentored dozens at all levels, including more than 50 undergraduates in his lab. He is the recipient of a National Science Foundation Career Award, the Dean’s Award for Distinguished Teaching by an Assistant Professor, and a University of Pennsylvania Department of Biology Excellence in Teaching Award, among other honors.
