Studying at WMU provided a multifaceted experience that extended beyond just academics, and there are two highlights worth mentioning to represent this. One, the amazing opportunity for intercultural exchange. I had the privilege of collaborating with researchers and experts from around the globe. This diverse gathering not only facilitated a unique learning environment but also opened doors to share varied perspectives. This exchange was instrumental to my research and learning process and enriched my career path. I found myself collaborating with and even speaking alongside some of the most respected experts in the field on renowned panels. Two, is a particularly exhilarating experience which was representing the university in the UN interagency games in 2022. I was honored to be a part of the first women's team from WMU.
