On May 7, The Graduate School will hold two hooding ceremonies for 2021-2022 Ph.D. graduates. Among them are numerous students who took advantage of the Bass Connections program to strengthen their dissertation research, coauthor publications and hone career-enhancing skills. Many students also engaged in other interdisciplinary opportunities across campus. Here is a quick look at six of them; congratulations to all of this year’s graduates!

“What I did as a researcher was unique, being able to help design, analyze, collect and publish. All my time in the field helped me understand what it’s like living in another community, know what’s going on and ask the questions to help.” –Axel Berky

“Not only have I had the opportunity to meet and learn from a variety of experts ranging from famous atmospheric chemists to former U.S. ambassadors, I also have had the experience of helping build a team of undergraduates, graduates and faculty, [and] learning about ozone depletion has helped shape the topic of my dissertation project more than any other single source at Duke.” –Kathleen Burns
