About me

Download my CV Google Scholar

I have always been interested in science, especially biology, since I was little. This brought me to Osaka University, where I conducted research on transcription regulation during my undergraduate and master’s studies. I have since moved to the Okinawa Institute of Science and Technology in Okinawa, Japan, where I work on the transcriptional regulation of the scrambled genome of Oikopleura dioica.

My research combines genomics, single-cell transcriptomics, and epigenomics to understand how gene regulation contributes to the conservation of morphology despite extreme genome rearrangement. I am also trying to build a pangenome for O. dioica. I mostly use R, Python, bash, and Nextflow, with a focus on reproducibility, and I build tools for the lab and the wider community — including a genome browser for O. dioica at oikobrowser.jnicolaus.com (soon to be migrated to oikobrowser.com).

In my spare time, I take care of my carnivorous plants, 3D print, watch football, fish, and scuba dive.
