Recently I had the pleasure and honour of sitting on the examining panel of a PhD thesis defence by Sergio Sayago, a researcher at the Interactive Technologies Group of Universitat Pompeu Fabra, in Barcelona. I met Sergio at W4A 2009, where he and his supervisor Josep Blat won the Best Paper award for their paper describing an ethnographic study of older people and their use of information and communication technology. Having enjoyed reading that paper and hearing his talks (he gave two at W4A), it was great to be able to announce that he’d successfully defended his PhD thesis.
