Hello! I am a Senior Deep Learning Scientist at NVIDIA. Previously, I was an Applied Research Scientist at Grammarly (2022-2023), a Senior Research Scientist at Megagon Labs (2017-2022), a Visiting Scientist at the Human Dynamics Group, MIT Media Lab (2014-2016), and a Research Scientist at NTT Laboratories (2008-2014). I received my B.E., M.E, and Ph.D. (Dr. Eng.) respectively from Keio University, Japan.

My research interest has been lying in the intersection of Machine Learning, Natural Language Processing, and Data Management, with a recent focus of Large Language Models. I also work on computational approaches for the social sciences known as Computational Social Science.

My current research scope can be categorized as follows:

• Text Summarization/Generation [EMNLP 2023] [ACL Findings 2022] [EMNLP Findings 2021] [TACL 2021] [ACL 2020]
• Table Understanding [VLDBJ 2023] [SIGMOD 2022] [VLDB 2021] [VLDB 2020]
• Information/Knowledge Extraction [WWW 2021] [NAACL 2019]

I’m a ramen enthusiast.

FAQ

• Q. Are you the famous green dinosaur?
  A. No. I’m not working with the famous Italian plumber, but both of us are originally from Japan. Yoshi means “good” in Japanese, and my full first name Yoshihiko means “a good boy”, which well describes myself. :)

• Q. What is your favorite ramen place?
  A. Please contact me for my private list of the best ramen places. :)
