Short Curriculum Vitae
Dr. Antonio Ancona received his Degree (cum laude) and PhD in Physics from the University of Bari in 1997 and 2002, respectively. From 2002 to August 2004 he was Post-Doctoral Research Assistant at the Physics Department, University of Bari. Since September 2004 he joined, as Technologist, the CNR. His research activities are mainly focused on the study of high power laser welding processes and laser ablation with ultrafast fiber lasers as well as on the development of real-time process sensors. Since December 2006 he has spent a 1-year sabbatical as visiting scientist and then a DAAD research fellow at the IAP - Institut für Angewandte Physik of the Friedrich-Schiller-Universität Jena (Germany), exploiting leading research in the field of ultra-short pulse micromachining and materials modification for industrial and medical applications. The results of his work are published in more than 30 scientific articles in premier peer-reviewed journals, 1 book contribution, 3 patents as well as in more than 60 invited and contributed conference presentations.
