Dimitrios Kleftogiannis

PhD Students

Research Interests

I work mostly on knowledge discovery technologies with applications in Bioinformatics and Computational Biology. ​My research interests include Machine Learning, Artificial Intelligence and Data Analysis of NGS-derived data. I have worked extensively on the prediction of distal DNA regulatory elements focusing of the category of enhancers. I am also involved in many other projects related to  pathway-based inference of host pathogen interactions as well as prediction of miRNA genes and targets.

Developed tools and deployed datasets


  • ​2011-Present: PhD in Computer Science at KAUST, Thuwal, SA. Advisor: Panos Kalnis.
  • 2009-2011:    Masters Degree in Informatics for Life Sciences, Medical School, University of Patras-Greece
  • 2003-2009:    Diploma in Computer Engineering,Computer Engineering and Informatics Department, University of Patras-Greece

Professional Profile

  • 2015 Oct / 2015 Dec Research trainee at RIKEN Yokohama labs. This project is related to enhancer/promoter exploration using CAGE, ChIP-seq and ChIA-PET  data. The scope is to develop a new methodology for analyzing clinical data produced by RIKEN labs.
  • 2013 Nov / 2014 Oct  Research assistant at Computational Biolofy Lab at National University of Singapore (NUS). During my internship in NUS I studied host-pathogen interactions at the metabolic pathway level. Outcome was the development of an algorithm called Hi-Jack, which identifies interconnections between human, and Mycobacterium Tuberculosis based on the idea of metabolite hijacking. I was under the supervision of Limsoon Wong.
