Personal information

Biography

David Megias achieved the PhD in Computer Science in July 2000 at the Universitat Autònoma de
Barcelona (UAB). He was an assistant lecturer at the UAB from September 1994 to October 2001. Since
October 2001, he is at the Universitat Oberta de Catalunya (UOC) with a permanent position (currently as associate professor). At the UOC, he has held several academic positions, such as director
of the Master programme in Free Software (from 2002 to 2009), associate director of the
Doctoral programme in Information and Knowledge Society (from 2009 to 2013) and director of the
Doctoral programme in Network and Information Technologies (from 2012 to 2013). In January 2014, he was appointed director of the Doctoral School. His current teaching is mostly related to computer networks, information security (watermarking and steganography), free and open source software and to research techniques and methodologies in the field of Network and Information Technologies. His current research interests include security and privacy in multimedia content distribution (mainly in the watermarking and fingerprinting topics), steganography and steganalysis. He has recently started a research line about privacy concerns in different applications of on-line social networks. He has published research papers in numerous
international journals and conferences and has participated in several national joint research
projects both as a contributor and as a manager (main researcher). He also has experience in international
projects, such as the European Network of Excellence of Cryptology funded by the European Commission within the Sixth Framework Programme. He is a member of the IEEE.
