The Department Colloquium is one of our initiatives to strengthen our identity as a Department and it provides a forum to internally present, discuss, and get feedback on current research projects. During the last two days, we had the 4^th edition of our Department Colloquium in Podersdorf at the Neusiedler See. Here, we shared a lot of inspiring research presentations and experienced lively discussions that hopefully help the presented projects to further develop and flourish. Apart from these research discussions, we really enjoyed the common time at the lakeside, had a walk to the lighthouse and topped the event off with some drinks and chats after dinner. We are looking forward to the next Research Colloquium in 2020!
