Data scientist at Biome Inc., Kyoto, Japan



In my childhood I wanted to be a shark taxonomist that would allow me to see various kinds of fishes and roam across the world. Yet, in doing undergraduate study I faced lot of difficulty to do so and I became more interested in evolutionary biology.

In the PhD course at Hokkaido University, Japan, I decided to work on freshwater fish to investigate how female ornamentation works and why interspecific mating happens. While I did behavioral experiment/field survey/citizen science for the fish, I also conducted meta-analysis to uncover general pattens of F1 hybrids’ phenotypic distribution.

In the late years of my PhD I became interested in ecology as well. To understand how the strength of predator-prey interaction between larvae of salamander and frog are determined, I did lots of experiments (sadly they are not published yet).

On 2021, thanks to JSPS, I got a chance to be a postdoc at the United States/Italy. However, due to covid-19 pandemic, I could not move to US and start the planned study. During the desperate period, I became interested in connecting evolutionary biology/ecology to society/economy because I watched NIKKEI TV everyday.

Now I came back to Japan and became a data scientist at a startup company Biome Inc.. While I keep my interest in evolutionary biology/ecology, I set connecting biology with society through citizen science as one of my career goals.
