Doubling genomes, translating everything else.

I study what happens to cancer genomes after they double. Master's student at Tokyo University of Science, doing research at a cancer research institute in Tokyo.

I came to Japan from Italy after high school without speaking the language, and now do all of my research in it. Before that I translated books. I work in Japanese, English, Italian and Persian.

The lab I joined works almost entirely at the bench. There was nobody handling the computational side when I got involved, so that became my work: the pipelines, the statistics and the tooling for a pan-cancer dataset. My supervisor sets the question; I design and run the analyses.

Selected work

Ploidy after whole-genome doubling

Research · cancer genomics

After a cancer cell doubles its entire genome it does not stay at that ploidy. It drifts back down, and where it settles depends on the cancer type. I built the analysis to ask what that tracks with, across 23 cancer types and around 10,000 TCGA samples: copy-number calling, differential expression modelled as a continuous function of ploidy rather than a two-group comparison, survival analysis, and deconvolution of bulk expression, with a simulated dataset used to check the pipeline recovers what it should.

Hotdog Counter

Software · published Obsidian community plugin

A plugin for Obsidian that counts matches across a vault using fuzzy regex, debounced so it stays responsive on large vaults. Published to the community plugin directory.

Workout tracker

Software · Python web app

A self-hosted training log that parses exported notes into structured data and reports progress per muscle group. Built mostly to find out whether the training was as consistent as it felt.

Seven books

Translation · 2019–2023

Seven books from Japanese into English as a freelancer, and one from English into Italian before that. It is where I learned that you cannot move a sentence into another language until you know exactly what it says.
