---

I'm currently working at Apple Inc. as an input method engineer.
Also, I'm a Ph.D candidate at Tokyo Institute of Technology, supervised by Prof. Hiroya Takamura and Prof. Manabu Okumura.
Previously I recieved my BSc from The University of Tsukuba (Japanese web page) under the supervision of Prof. Takashi Inui.
My research interest is in machine learning for natural language processing, and I am particularly interested in making machine more robust to lexical diversity as in social media.
Outside the university, I have worked on social media analysis and natural language generation from numeric data (data2text).
