Dimitri Kartsaklis is a computer scientist and computational linguist working as a research associate in the EPSRC-funded project "Semantic Interpretation of Personal Health Messages" (PI: Nigel Collier). He completed his Ph.D. at the Quantum Group of the Computer Science Department, University of Oxford, where his research was focused on category-theoretic compositional models of natural language. After his Ph.D. he continued his research on compositionality and natural language semantics for 2.5 years as a post-doctoral researcher in the Theory Group of EECS, Queen Mary University of London. He also holds an MSc in Artificial Intelligence from the University of Edinburgh. Before being engaged in scientific research, he was a software engineer and system analyst for more than 15 years.
