Bio:

Stefan Pantazi is a medical doctor trained in General Medicine. His keen interest in computing led him to Medical Informatics. In his doctoral dissertation "A Deterministic Dynamic Associative Memory (DDAM) Model for Concept Space Representation," he explored research topics in the areas of knowledge discovery and representation, with relevance to Case-Based Reasoning, Natural Language Processing and Information Retrieval.

Dr. Pantazi's interest in uncovering fundamental aspects of Medical Informatics and medical decision-making led to a strong emphasis on computational models of information processing. This has resulted in the creation of the notions of “knowledge spectrum” and of “usability axiom of medical information systems,” two novel concepts, developed, refined and published in peer-reviewed journals. Both these concepts helped convey fundamental aspects of Medical Informatics to students and to other audiences and allowed for the proposal of a new definition of Medical Informatics as "context-dependent processing of medical information," a view fundamentally linked to such research areas as Case Based Reasoning, Information Retrieval and Algorithmic Information Theory.
