He is an Assistant Professor at The University of Tokyo, a Co-founder at miup Inc., and a Technical Advisor at Panasonic, Inc..
He obtained his Ph.D. on statistical time series analysis and computational biology from the Graduate School of Informatics, Kyoto University. During his doctoral studies, he also co-founded a start-up called "CRUNCHERS Inc.," to bring Information Science together with Art. At CRUNCHERS Inc., he developed a novel evaluation system centered on natural language processing technology and a box-office revenue forecasting system for movies (CRUNCH CINEMA). The start-up transferred its business in January 2015.
After his Ph.D., he became an Assistant Professor at Tohoku Medical Megabank Organization, Tohoku University, where he focused on genome wide association study (GWAS) especially for rapid analysis of rare mutations. He also became a technical advisor to a team that was developing a medical disease inference system using Bayesian learning and an influenza-infection prediction system based on time-series data.
He was appointed to his current position in 2015, where he has four key focus areas. First, he is involved in the development of a novel statistical methodology for the inference of the internal states of time series data and the prediction of their future states. Second, he focuses on cancer-immunogenomics and the development of their analysis tools in the International Cancer Genome Consortium. Third, he handles the stratification analysis of GWAS using cohort data, and lastly, he is involved in the predictive analysis of time-series health check-up data integrating blood test values, social status, lifestyle habits, genomic data, and so on. He also has experience serving on committees and evaluation boards at various ministries and agencies. He has extensive knowledge of labor laws and dispatch law operations at medical sites.
He has also served as a technical advisor on production and experiment optimization to several large companies. Further, he has guided the development of AI systems (statistical science and machine learning) at startups. Especially in miup Inc. from the University of Tokyo, he formulates the business strategy and oversees progress management, capital policy, and foreign negotiations. He has handled the business right from the inception of the company, well into its growth phase.

Our research topics are analyzing human genome, transcriptome, epigenome, metagenome and clinical data for personalized and preventive medicine through modeling, prediction and inference of disease and health systems. For example, we have been undertaking immunological cancer genome and metagenome analysis based on statistical and machine learning methods.
Especially, in the field of statistical science, my speciality is computational statistics and stochastic simulation, such as data assimilation and have published many research papers.
miup Inc. is trying to establish "Integrated Healthcare Eco-System" using IoT technology and clinical A.I. system starting from developing countries to developed countries. Firstly, we have launched a home delivery health-care service in Bangladesh.
My role is to design business strategy, make financial indication and capital policy, raise funds, and manage our team.
Our system has a highly complicated statistical structure to enhance the quality of the inference, estimate the confidence level of the conclusions, and predict the future risks through Bayesian statistics and machine learning.
Detail is Confidential: Production and experiment optimization of an image processing devision based on Bayesian framework.
Confidential: Advising labor laws and dispatch law operations at medical sites.
We developed an automated consulting system termed Mogul for medical treatment. This system is a type of artificial intelligence and based on a simple Bayesian inference procedure (Its concept is similar to the one in miup Inc. but this version is a little bit older). Also, a pandemic prediction system for the degree of future influenza epidemic has been released in the website.
Confidential: Education for A.I. development especially for image processing.
Confidential: Consultation of data science and A.I. business.

The main topic was genome wide association study and to develop novel strategies for analyzing rare variants association test. Our developed method is highly efficient and available to WGS data within a reasonable time. In addition, we proposed a novel statistical method termed kernel Bayes' approximate Bayesian computation filtering for estimation of parameter values in stochastic simulation models.
We developed automated evaluation systems for predicting the profit of books and cinema. The former system was integrated to Medley, Inc. as CRUNCH MAGAZINE. For the latter system, I still have advised the statistical perspective of applying the developed simulation system (CRUNCH CINEMA) to the collaborative companies. In addition, since we're collaborating with major studios and major entertainment companies in JAPAN and USA, we have extended and developed CRUNCH CINEMA for the application of general purpose.
