Staff profile

I am an Assistant Professor (Teaching) in the Department of Computer Science. I graduated from the Department of Mathematics of Patras, Greece, in 2010, followed by an MSc in Mathematics of Computation. I completed my PhD in "Algorithmic Aspects of Temporal Graphs" in 2016. My teaching role involves both undergraduate and postgraduate Computer Science students.

Research Groups

• Algorithms and Complexity

Research Interests

My research interests lie in the field of algorithms, with a focus on dynamic networks, including:

• probabilistic methods in algorithms,
• algorithms and complexity of graph theoretic problems, and
• optimization problems in dynamic networks.
