Dr. Papadakis interests include Wavelet Analysis, Frame Theory, Biomedical Image Analysis (Atherosclerotic Plaque in Coronary and Carotid Arteries, Neurobiology), and Seismic Imaging. The primary focus of his research is to find ways to eliminate the errors in computer vision applications resulting from the directional preference of software due to the use of one-dimensional filter designs. Dr. Papadakis and his collaborators propose that the best antidote to this is the use of isotropic filtering methods, treating all directions equally and enabling the handling of multidimensional data sets in their original dimensionality. Moreover, coupling these new filtering techniques with state-of-the-art artificial intelligence methods seems to be promising for future breakthroughs in diagnostic medical imaging.

Nikos Paragios is professor at the Ecole Centrale de Paris - one of most exclusive engineering schools "Grande Ecoles" - leading the Medical Imaging and Computer Vision Group at the Applied Mathematics Department. He is also affiliated with INRIA Saclay Ile-de-France, the French Research Institute in Informatics and Control heading the GALEN group, a joint research team between ECP/INRIA. Prior to that he was professor/research scientist (2004-2005) at the Ecole Nationale de Ponts et Chaussees, affiliated with Siemens Corporate Research (Princeton, NJ, 1999-2004) as a project manager, senior research scientist and research scientist. In 2002 he was an adjunct professor at Rutgers University and in 2004 at New York University. Professor Paragios has co-edited four books, published more than hundred-fifty papers (DBLP server) in the most prestigious journals and conferences of medical imaging and computer vision, sixteen US issued patents and more than twenty pending. His work has approx 5,000 citations according to googlescholar and 2,500 according to scopus, and and his H-number according to scholar is 31 and 25 according to scopus. Professor Paragios is a Senior member of IEEE, associate editor for the IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI), area editor for the Computer Vision and Image Understanding Journal (CVIU) and member of the Editorial Board of the International Journal of Computer Vision (IJCV), the Medical Image Analysis Journal (MedIA), the Journal of Mathematical Imaging and Vision (JMIV) and the Imaging and Vision Computing Journal (IVC). Professor Paragios is one of the program chairs of the 11th European Conference in Computer Vision (ECCV'10, Heraklion, Crete).

In 2008 N. Paragios was the laureate of one of Greece's highest honor for young academics and scientists of nationality or descent (world-wide), the Bodossaki Foundation Prize in the field of applied sciences. In 2006, he was named one of the top 35 innovators in science and technology under the age of 35 from the MIT's Technology Review magazine (article). His research interests include image processing, computer vision, medical image analysis and human computer interaction.

Theoharis received a B.Sc. degree in Computer Science from the University of London in 1984, M.Sc. degree in Computation from the University of Oxford in 1985 and Ph.D. in Computer Graphics and Parallel processing from the University of Oxford in 1988. He served as a Research Fellow at the University of Cambridge between 1987 and 1990 and as a Consultant with Andersen Consulting between 1992 and 1993. His main research interests lie in Biometrics and 3D Object Retrieval and Archaeological Reconstruction. He has co-authored a textbook titled: 'Graphics & Visualization: Principles & Algorithms', A.K. Peters, 2008.
