Graduate students’ visually engaging research recognized at annual Vizzies


UNIVERSITY PARK, Pa. — The Penn State Department of Mechanical Engineering recently celebrated its graduate students and their visually engaging research during the 2022 Vizzies. The Vizzies are an annual departmental competition, based on the National Science Foundation initiative, that recognizes compelling scientific research. This year, Dailen Brown took first place with his image, “Hope Shines Through.” Brown, who is advised by Jason Moore, associate professor of mechanical engineering, submitted the image in honor of medical professionals around the world. Brady Sawyer placed second with his image, “Microstructure of an Additively Manufactured Nickel Alloy,” and Nandana Menon placed third with her image, “Interface Microstructure of Additively Manufactured IN718.” The People’s Choice winner, determined by receiving the most likes on Facebook, was Md Abu Jafar Rasel for his image, “In-situ Biasing and Strain Map.”
