My Schools
Being in a school setting always helps me feel rejuvenated and energised. Each of these places has shaped who I am today.
UNIST
PhD · Creative Design Engineering (Human-Computer Interaction) · Ulsan, South Korea · 2017–2021
UNIST is located in Ulsan, surrounded by mountains and fresh air — a perfect environment for focused research. Moving there in Fall 2017 was my first time living outside Thailand. I had both challenging and deeply rewarding experiences at the Interactions Lab and the DxD Lab, advised by Ian Oakley and Hwajung Hong.
Asian Institute of Technology (AIT)
MSc · Computer Science, specialisation in Software Engineering · Thailand · My all-time favourite
AIT is one of the top international graduate schools in Asia, and it truly feels like a second home. The campus is surrounded by trees, restaurants, and bicycle paths — cyclists rule the road there! I was privileged to be taught by exceptional professors and to make friends from countries all over the world. I miss AIT dearly.
Stamford International University
IT Lecturer & Acting Head of Department · Bangkok, Thailand
An internationally renowned school in Bangkok with students from over 100 countries. I served as IT Lecturer and loved meeting such a diverse group of talented people. Watching many of them go on to successful careers in programming and design is something I carry with me.
Mahanakorn University of Technology (MUT)
BSc with First Class Honors · Information Technology · Bangkok, Thailand
MUT is where my journey truly began. Five years as a student, then as a junior lecturer — the professors there helped ignite my passion for programming and set me on the path to everything that followed. I will always be grateful.
