In February 2011, Angel Rivas successfully defended his PhD thesis. Angel started his PhD at the University of Hertfordshire and followed the big move to Ulm in 2009. You can read a nice introduction to Open Quantum Systems in a recent Springer publication that emerged from his thesis. The German students in the group make sure that traditions were kept and made him a gorgeous doctoral hat which included a heat bath and a chain mapping!
Angel is now a postdoc at the Universidad Complutense de Madrid, working in the group led by Miguel Angel Martin-Delgado.
