I am a professor of Computer Engineering at the Middle East Technical University (METU), Ankara, Turkey.

My research interests lie in the areas of machine learning for bioinformatics, machine learning applications and data clustering.

I am currently member of the International Technical Advisory Board of Arcelik (Research and Development Directorate), the Technology Advisory Board of Turkish Aerospace Industries (TAI) and Board of Directors of Izmir Biomedicine and Genome Institute (iBG-izmir).


I have obtained “Diplôme de Docteur dans la spécialité Informatique” (Ph.D in computer science) from Université Paris Descartes, Paris, France. During sabbatical leave, I spent a year (2004) at Virginia Bioinformatics Institute, Virginia Tech, VA, USA.
From 2010 to 2016, I was the Vice President for research of METU and Chairman of Board of Directors of ODTU TEKNOKENT (METU Technopolis). My main responsibilities included strategies and policies for research and for university-industry partnership, relations with both public and private institutions, and corporate strategy management.
I am still involved in activities related to technology based innovation, technology based entrepreneurship, technology management, and research policies and strategies.

My research interests lie in the areas of machine learning for bioinformatics, machine learning applications and data clustering.

In the last 10 years, I am involved in machine learning for bioinformatics. My research efforts are focused on developing and applying computational techniques for the analysis of biological data and modeling of biological processes at the molecular level. The broad aim is to provide computational tools to assist researchers to understand, explain and predict the behavior of complex biological systems. My research activities take place in the Cancer Systems Biology Laboratory.

I am currently involved in the following two research projects:

  • Genome Annotation based on Sequence Analysis

For the analysis of sequences, we have developed a generative system based on feature space mapping, called Subsequence Profile Map (SPMap). SPMap can be fed to a discriminative classifier for prediction purposes. Instead of focusing motifs in a sequence, SPMap considers all of the subsequences as a distribution over a quantized space by discretizing and reducing the dimension of an otherwise huge space of all possible subsequences. We have already applied SPMap and other feature generating methods to the following problems:

Automated Protein Function Prediction
Enzyme Class Prediction

  • Generating Readable Layouts for Biological Graphs

Although force-directed layout algorithm could be used to draw biological graphs, modification is required when we would like to embed domain-specific knowledge. We proposed a modified and improved (Kamada-Kawai) force-directed layout algorithm, EClerize, to generate more readable layouts for biological graphs that represent pathways in which the vertices are identified with EC (Enzyme Commission) numbers. While the vertices with the same EC class numbers are treated as members of the same cluster, positions of vertices in clusters are affected by the biological similarity of each vertex in the same cluster and the theoretical length between the vertices.
