Senior International Educator based in Yokohama with over 20 years of experience. Appointed and standardised in 2026 as a Cambridge PDQ Examiner for an international teacher professional development qualification. My work sits at the intersection of Computer Science, Library and Information Science, and Linguistics, which means I teach not just tools, but the underlying logic of information and design.

Background

About Me

I have worked in international education and academic research for over 20 years. Along the way I completed an M.Sc. in Computer Science Education, building on my Ph.D. in Linguistics and an earlier degree in Library and Information Science. This combination shapes how I think about technology: not as a set of tools to be mastered, but as a cognitive and informational practice.

My classroom experience spans humanities and technology subjects across international schools in Hungary, Germany, and Japan. I am particularly interested in how students process complex information and how to make digital logic feel intuitive and accessible. The Design Cycle and Information Literacy run through most of what I do. I am now based in Yokohama as a local resident.

In 2026, I took on an external portfolio assessor role with Cambridge International for the PDQ programme Teaching with Digital Technologies.
