Taken in 2019

Hi, call me Mew for short. I am a Software Engineer at Astellas Pharma Inc., a global pharmaceutical company headquartered in Tokyo, where I design and develop agentic AI systems.

I learned about Concept drift in grad school, but it’s not that popular so I picked up Natural Language Processing (NLP) on my first job, and have been working on it ever since.

I earned my master’s degree in Information Science in 2018 from Osaka University, and bachelor’s in Computer Engineering in 2015 from Chulalongkorn University.
