Unraveling biological systems and contributing to medical sciences by a combination of biophysics and quantitative genomics.

Research Summary

I had been working on single molecule observation of molecular motors by optical microscopy, and have jumped into the genomics research field. Based on these experiences, we are making a new platform enabled by the combination of imaging, sequencing, and machine learning. Using this system, we would like to understand biological systems, and to contribute to medical sciences. We have developed other techniques as well, for example, molecular barcoding which provides digital RNA sequencing (dRNA-seq), and a novel bacterial microbiota analysis based on single-base identification and single-cell level quantification. We often collaborate with biologists and/or medical scientists in order to study immune cells and diseases.

Research Theme

  • Molecular barcodes for digital quantification of nucleic acid molecules
  • Digital RNA sequencing (dRNA-seq)
  • Novel bacterial microbiota analysis
  • Combination of bio-imaging, sequencing, and machine learning
