Iro Oikonomou Computer Science and Mathematics

I am a dedicated tutor with a strong background in computer science and mathematics, currently pursuing a Master’s degree in Algorithms, Logic, and Discrete Mathematics. Over the past several years, I have gained extensive experience teaching and tutoring at different levels — from high school mathematics to university programming and linear algebra labs.

My research focuses on algorithms, linear algebra, and numerical analysis, and I have published in prestigious international journals on topics such as spectral radius bounds and interpolation methods. This academic foundation allows me to bring both depth and clarity into my lessons, making even the most abstract concepts accessible to students.

I have worked as a teaching assistant at the National Technical University of Athens and as a volunteer instructor, while also offering private tutoring in mathematics since 2018. My approach is student-centred: I adapt lessons to each learner’s needs, help them build confidence step by step, and encourage critical thinking and problem-solving.

Beyond academics, I am an active musician and believe that creativity and discipline go hand in hand — qualities I also bring to my teaching.

If you are looking for a tutor who combines strong subject expertise with patience, adaptability, and enthusiasm, I would be happy to support your learning goals.
