Our teaching and research assistant, Tomislav Antić spent six months between March 1st and September 1st, 2022 at University College Dublin where he was working as a visiting researcher under the supervision of professor Andrew Keane. During his stay at UCD Tomislav was working on the development of optimization models used in the planning and operation of distribution networks. Tomislav is very satisfied with his time at UCD since he learned a lot, made progress in his PhD research, but also exchanged experiences with other researchers and made a lot of connections that will be helpful in future work.
