I am passionate about modeling real-world business problems using advanced machine learning methods. I have a strong track record of successfully leading numerous customer engagements to deliver first-of-a-kind AI solutions across various industries. Many of the core algorithms I developed in these projects have been published in top AI and data mining conferences such as AAAI, IJCAI, ICDM, and SDM, establishing me as a leading expert in AI-powered industry solution development at IBM.
In particular, I am recognized as an expert in anomaly and change detection, as evidenced by the two textbooks I have authored. My primary interest lies in extracting actionable insights from AI algorithms. For example, you can read my thoughts on the explainability of AI in my LinkedIn article,, which is based on my recent papers published in AAAI 2021 and KDD 2023. My other recent research interests include causal discovery from stochastic event data for AIOps (NeurIPS 21, AISTATS 24) and graph neural networks (AAAI 2022, ICASSP 2023).
Currently, I serve as the Head of Data Science for IBM Semiconductors at the IBM Research Division. In this role, I lead several strategic initiatives, including defect causal analysis of the state-of-the-art 2-nanometer semiconductor fabrication process and simulation-based fab-wide optimization.
My almost two decades of experience in delivering AI-powered business solutions covers industries such as:
- Semiconductor manufacturing
- Fault detection and classification
- stochastic WIP simulation and optimization
- Statistical process control
- Condition-based monitoring:
- Automotive (sensor analytics, experimental design, failure diagnosis, EV fleet management, etc.)
- Oil and petroleum
- AIOps (event causal analysis)
- Financial (Stock price monitoring, blockchains, collaborative learning, etc.)
- Mining
- etc.
- Healthcare (diabetes data analytics)
- Transportation
- Railway
- Maritime
- Traffic simulation
- Travel time prediction
- LCD optics design
- Statistical project management
- Power grid failure analysis
In addition to broad industry knowledge, I have years’ of people and project management experience both in Japan and the US. I have done much work also in intellectual property management, handling many non-disclosure agreements, technology license agreements, and service contracts.
Back in Japan, I was known as a collector of antique computer keyboards. You can check some of my collection of mechanical keyboards on my YouTube channel. I also run a website on the history of modern computer keyboards (in Japanese). Enjoy!
