I'm an Assistant Professor at The University of Tokyo, a Co-founder / Collaborative Researcher at miup Inc., Technical Advisors at Panasonic, Inc. and CareLab Inc. with expertise of Computational Statistics, Time-series Analysis (Data Assimilation), Applied Statistics, Bioinformatics, and Machine Learning. I'm interested in applying technological developments in computer science and biotechnology for the innovation of human being. Also, I'm currently very interested in financial strategy and business development (focusing on these roles in miup Inc.).
In the field of Computational and Applied Statistics, I have developed several types of data assimilation methodologies, e.g., linear/nonlinear Kalman filters. In practical research of Computational Biology and Genomics, I have analyzed human genome/health and epidemiological data such as time-series medical examination data to predict future health risks and cancer genome sequencing data for the elucidation of immuno-cancer relationship and the development of personalized medicine. In Business field, the current interest is to develop several types of artificial intelligence systems utilizing, e.g., Bayesian statistical inference, for the application of medicine, health and nursing care, and immune-cancer therapies, and also to design financial and business strategies.
I'm also studying modern history, classical strategy, e.g., Hundred Schools of Thought and The Prince, geopolitics and philosophy as life works.

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.
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.
