Research Summary

Gen  Tamiya(Ph.D.)

Using AI-based methods in statistical genetics, we analyze Big Data consisting of a wide variety of information such as genomic variations, lifestyle and health status, co-existing microorganisms including pathogens together with an enormous medical literature in order to identify causal factors for complex common diseases. We aim to enable genomic risk prediction for complex common diseases and then to realize personalized and preventive medicine. Chiefly we investigate Big Data from large-scale prospective genomic cohorts such as the Tohoku Medical Megabank organization. We apply the similar approach to agriculture and other life science data.

Research Subjects:

  • Statistical genetics of prospective genomic cohort and other life science data

Main Research Fields

  • Biological Sciences

Related Research Fields

  • Agricultural Sciences
  • Informatics
  • Mathematical & Physical Sciences
  • Medicine, Dentistry & Pharmacy
  • Human Genetics
  • Epidemiology and preventive medicine
  • Science in genetics and breeding

Keywords

  • Genome Cohort
  • Statistical Genetics
  • Gene-Environment Interaction
  • Machine Learning
