PhD

• Topic: Deep Reinforcement Learning Methods
• Supervisor: Prof. Ioannis Vlahavas

Short CV

Ι received my diploma in Mathematics (2013) from the department of Mathematics, Aristotle University of Thessaloniki (AUTh). From the same department I also received my master’s degree in Theoretical Computer Science and Theory of Systems and Control (2016). Since 2018, I am a PhD candidate in the department of Informatics, AUTh, under the supervision of prof. Ioannis Vlahavas.
My research interests are (Deep) Reinforcement Learning algorithms and their applications in the games domain.
