We are happy to host the first of hopefully many exchange PhD students from the Universidad de Antioquia (UdeA) in Medellin Colombia. John Byron works under the supervision of Prof. Fredy River and Prof. Ricardo Velasquez at the Department of Electronics where he is affiliated to the SISTEMIC lab. John Byron Buitrago received his BSc. diploma in Electronics Engineering in 2005 and his Master Degree on Engineering in 2014 from the UdeA. He started his PhD in the same institution in 2016, working on methodologies for the automatic synthesis of computer architecture simulators onto parallel platforms. John Byron will be collaborating with researches at the CC Chair for the next six months on methodologies to automatically generate efficient simulators with special focus on the uncore. We look forward for a collaborative winter term!
