Research Overview

3D (epi-)genome at single-cell resolution

My research interest is to understand full spectrum of cis-interaction to gain insights into evolution and human diseases by genomic rearrangements. I have recently developed a system, named STITCH, to control gene-enhancer interaction by drugs (Tsujimura et al. 2020 eLife). Exploiting the unique system, I would like to further dissect out the process of gene activation by long-range enhancers, and how it is regulated in the genome.

The field of epigenomics is being accelerated by rapid revolution of technology to analyze the epigenomic and transcriptomic states of individual cells. I am also engaged in development of novel analytical tools for single-cell epigenomics. Taking advantage of the collaborative environment at ASHBi, I would like to apply these techniques and others for the the studies of myself and others, to establish a cutting-edge concept in the field of human biology.

Biography

Taro Tsujimura obtained his PhD from the University of Tokyo for his study in the regulation of tandemly duplicated opsin genes in zebrafish (2008). In 2009, he moved to EMBL Heidelberg in Germany and studied the relationship between genomic organization, chromatin conformation, and enhancer regulation as a postdoc. In 2014, he became a Research Assistant Professor at University of Tokyo Hospital, and then at Keio University School of Medicine until 2019. He is now appointed as Junior Associate Professor at ASHBi, Kyoto University.
