EUC Colloquium on Mathematics, Computer Science and Engineering

The EUC Colloquium on Mathematics, Computer Science and Engineering  was established in November 2011 and is organized by the Department of Computer Science of the European University Cyprus. The purpose of Colloquium is to provide a forum to our colleagues, our current and potentially future collaborators as well as known scientists to meet, present research findings, and discuss developments on a variety of topics spanning all important fields of Computer Science and Engineering. It also aims to provide an environment in which graduate students can gain experience in presenting their work, and benefit from contact with established researchers. The scope of the colloquium includes all aspects of Computer science, including Networks, Software Engineering, Databases, Algorithms, Theoretical Computer Science, Human Computer Interaction, High Performance Computing, and Operational Research, as well as aspects of Mathematics and Engineering.

If you are interested in giving at talk at the Colloquium, please contact the coordinator Dr. Vicky Papadopoulou by filling out the Colloquium Form.

 Generic ideas for tackling ill-posed inverse problems




11:30 - 14:20




In many scientific problems there is a need to infer from a set of observations a model that might be in some sense be considered fundamental or even be causally related to the generation of the data.  Very often if we know the model and all its parameters it is sufficient to compute exactly and uniquely all possible observables at least in principle.  The inverse problem however, that is completely defining the model from all possible measurements, may be impossible. In many such problems it can be shown that there is an infinite set of solutions that can fit the available data exactly.  The talk will outline how three such non-unique inverse problems have been tackled, one in the inverse scattering problem in nuclear physics (Ioannides and Mackintosh, 1987, 1985) and the other two in the biomagnetic inverse problem (one for the steady current of the human leg (Ioannides and Grimes, 1986) and the other for imaging brain activity at millisecond and millimeter spatiotemporal resolution (Ioannides et al., 1990; Ribary et al., 1991; Taylor et al., 1999)).  The generic ideas that lead from the first to the other two approaches will be summarized, and used as a guide for discussion about extending the methodology to more refined analysis of brain activity (Ioannides, 2007) and new areas of applications with potentially highly promising results.

Short CV

Prof. Andreas A. Ioannides was born in Morphou, Cyprus. He studied Physics (1970-73) and completed his PhD at Surrey University UK (1973-76), continuing with research in nuclear Physics until 1988. Since 1986 he started research in biology that by 1989 narrowed to magnetoencephalography. The initial emphasis on basic theory and mathematical analysis techniques lead also to development of experimental protocols and dedicated hardware (freely donated to the community with some nowadays installed in MEG systems world-wide). Prof. Ioannides established theoretical teams and set up functional neuroimaging laboratories in international centers of excellence in the UK (1989 -98), Germany (1994-8) and Japan (1998 – 2009) leading to over 130 scientific papers. Over ten of his PhD students are now leading scientist, some heading international centres of excellence in Europe, North America and Asia. Prof. Ioannides returned to Cyprus in 2009 as the director of AAI Scientific Cultural Services Ltd (AAISCS) a private company that continues the basic (neuro)science research of previous years with the additional goal of using the resulting knowledge to develop new services and products with cheaper and widely accessible technology. The company also provides support for experiments and data analysis in Electroencephalography and Magnetoencephalography.  The company is also exploring research opportunities in other areas of physics, biology and medicine with special interest in adapting the original inverse problem approach for new applications through collaborations with experts with specialized domain expertise in these disciplines.
