Welcome to Valéria Romano, presently a postdoctoral researcher at the University of Alicante, Spain. Valéria is back to the DEPE and will be mainly working on human cultural evolution. Her research focuses on the interface between socio-spatial structure and cultural transmission using the archaeological record.

Congratulations

Congratulations to Valéria Romano and the Paleodem team (Javier Fernández-López de Pablo and Magda Gómez-Puche, http://paleodem.eu/), which got the Summer Course "Introduction to Modelling in Archaeology" selected by the Rafael Altamira call - University of Alicante, Spain.

• Welcome to Ines Fache, Master II from the University of Strasbourg, who started her Master II degree with J Bleu (ADAGE team, IPHC-DEPE), F Criscuolo and S Zahn on environmental factors driving breeding success and telomere dynamics in the little owl (Athene noctua). This work is based on the long-term database set-up since 2001 by Alsacian volunteers, managed by Bertrand Scaar. This program is conducted in collaboration with the Ligue de Protection des Oiseaux.
