Virgil-Florin Duma is Professor of Engineering at the Aurel Vlaicu Univ. of Arad (UAVA), head and founder of the 3OM Optomechatronics Group, and PI of a Partnership Project ( of the Romanian National Authority for Scientific Research. He received his PhD cum laude in Fine Mechanics & Optics in 2001, from the Polytechnics Univ. of Timisoara (UPT), Romania, after graduating at UPT in 1991, first of year. He has worked at UPT since graduating until 2001, when he moved as an Assoc. Prof. at the UAVA, where he reached full professorship in 2006. He was awarded for 2009-2010 a Fulbright Senior Research Fellowship at The Institute of Optics, Univ. of Rochester, NY, where he currently holds a Visiting Scientist position. He is also Visiting Senior Research Fellow at the Univ. of Kent at Canterbury, UK, as well as Adjunct Prof. at the West Univ. of Timisoara and at UPT (at the latter, as PhD supervisor). Prof. Duma defended his Habilitation Thesis in 2013 at the Polytechnics Univ. of Bucharest. He is author of more than 180 publications in journals and conferences, 15 books & book chapters, 1 patent awarded and 2 patent applications pending ( His main research interests are in Measuring Systems, Optics, and Optomechatronics. Prof. Duma is a member of OSA and a Senior Member of SPIE.
