Apostolos Antonacopoulos leads the Pattern Recognition and Image Analysis (PRImA) research Lab at the School of Science, Engineering & Environment at the University of Salford, UK where he currently holds the post of Professor of Pattern Recognition. He received his PhD from the University of Manchester, Institute of Science and Technology (UMIST), UK in 1995. From 1995 to 2004 he worked as Lecturer in the Department of Computer Science at the University of Liverpool where he founded the PRImA Lab. In 2005, he joined the University of Salford as Senior Lecturer and the PRImA Lab was established and strengthened at Salford. In the same year, he received the IAPR/ICDAR Young Investigator Award for "Outstanding service to the ICDAR community and his innovative research in historical document processing applications."

Professor Antonacopoulos has worked and published extensively on various problems in Document Analysis and Understanding (Image Enhancement, Segmentation, Recognition, Performance Evaluation) as well as on other applications of Pattern Recognition and Image Analysis. He has co-edited the first Special Issue (IJDAR) on Historical Document Analysis as well as the first book on Web Document Analysis. He has served as a member of the Editorial Boards of the International Journal on Document Analysis and Recognition and of the Electronic Letters on Computer Vision and Image Analysis as well as an Associate Editor of Cultural Heritage Digitisation.

He is currently serving on the Executive Committee of the International Association for Pattern Recognition (IAPR) as Past President, having also held the posts of President, 1st and 2nd Vice President, and Treasurer. He has also chaired or served as a member of a number of IAPR and other professional committees. He has given a number of invited talks and tutorials and has held engagements as a technical advisor to libraries and archives, among which are the British Library and the Wellcome Library. He has been active in the organisation of conferences and workshops and is a member of the programme committees of most conferences in his field. He has significant experience in leading and participating in national, European (H2020 and earlier) and industry-sponsored projects. Recent significant project involvement includes the €4M Europeana Newspapers EU-funded project (extraction and recognition of text in newspapers for the European Digital Library), the €1.8 SUCCEED EU-funded support action for the Centre of Competence in Digitisation, the US$734K Early Modern OCR project (EMOP) funded by the Andrew W. Mellon Foundation, and the £250K 1961 Census small area statistics digitisation project funded by the Office of National Statistics (ONS). Currently, he is leading a £500K project funded by ONS to digitise and model the data in the published census reports from 1921, 1931, 1951 and 1961.

In the most recent Research Excellence Framework (REF2021) - the research quality evaluation of UK Universities - the research impact case study he lead on "Enabling Digital Transformation through Effective Digitisation" received the maximum rating of "Outstanding" (4*) in terms of both significance and reach.
