New book: Rigorous Software Development - An Introduction to Program Verification, by HASLab members J.B. Almeida, M.J. Frade, J.S. Pinto and S. Melo de Sousa.

'Cum laude' award: HASLab external student Alexandra Silva was awarded the "cum laude" mention for her doctoral thesis on Kleene Coalgebra, on Dec., 21st, 2010, at Radboud Universiteit Nijmegen. more...

This distinction is only given in the NL in very exceptional cases (less then 5% of all possible candidates). It requires the explicit support of the thesis committee as well as of two other experts in the area (in this case Samson Abramsky, Oxford, and Larry Moss, Indiana). During the committee meeting, Dexter Kozen gave the following justification for his own vote (quoted from memory): "in very rare occasions a doctoral thesis and defense changes the way one sees his own main research area: this was such an occasion and that is all I have to say". Congratulations, Alexandra!
