The Society for Experimental Mechanics (SEM), on behalf of its Technical Division (TD) on Data Science, has awarded Georgios Tsialiamanis the TD?s 2021 best paper award for its contribution to data analytics (in a broad sense). The paper entitled ?On an application of Graph Neural Network Approach to Population Based SHM? is to be presented at IMAC-XXXIX (session 26, Tuesday, Feb. 9, 1:20-2:30 p.m.). The manuscript, selected amongst more than twenty submissions has thoroughly impressed the selection committee with its clarity, innovative spirit, technical soundness, and relevance to IMAC?s interests in sound and vibration, health monitoring, and structural dynamics. It was a challenging competition, with several high-quality submissions, which further indicates the quality of Georgios’s work. Well done!
