About
As a Solutions Architect at NVIDIA, I work with Japanese enterprise customers on large language model training and inference, with a focus on the NeMo framework. I joined NVIDIA in February 2026.
Previously, as a Researcher and Tech Lead at Preferred Networks Inc., I engaged with clients in the healthcare and life sciences sectors and led BtoB solutions built on large language models.
I have experience formulating problems through consultation with clients and delivering deep-learning / machine-learning solutions, and I was the main mentor for four research interns and one part-time engineer.
During my PhD in the Department of Physics at the University of Tokyo, I developed machine-learning methods for gene expression and mutation data to tackle antibiotic resistance in bacteria.
