Teaching experience
Laboratory volunteer at the National Kapodistrian of Athens (teaching LaTeX, Linux using interactive whiteboard 2013-2015 (MATH123).

Teaching annual seminars at the computer laboratories at central.ntua of the National Technical University of Athens during 2016-2019 and winter semester 2019-2020.

In computer laboratories I have taught as adjoint faculty the following courses
1. Software for Mathematics and Physics (Winter semesters)
2. Numerical Analysis II (Summer semesters)

During 1/10/21-11/02/22 I have taught the courses “Mathematics I” and “Mathematics IIΙ” at the department of Mechanical Engineering of the University of West Macedonia (autonomous teaching)

During the time period 2019-2022, I have been providing teaching of mathematics courses, creating and supporting eclass sites, correcting and grading of undergraduate students exams at the Mathematics department of the university of Athens, the mathematical sciences department of the national technical university of Athens and the University of West Macedonia (autonomous teaching) .
I have been teaching mathematics as an associate teacher in Greek public high schools from 2017 until present

Other activities
During the period 2009-2011, I have been elected as a Secretary of the postgraduate students association at the department of Mathematics, University of Athens. During my tenure, I was responsible for the organization of seminars that provided useful knowledge of mathematical tools like Matlab, Maxima, LaTeX, necessary for the successful projects completion of my fellow students, with the use of interactive blackboard.
Useful notes were also provided, advice and assistance to undergraduate students for their well-being in the university academic environment.
Active member of the chess club ΠΟΚΕΑΤΕΠ. Third prize at the panhellenic chess tournament 2012.
