Space physicist · plasma simulations & open-source tools

I model plasma in planetary magnetospheres — from quasiperiodic Alfvén-wave resonances at Saturn to magnetotail reconnection feeding the terrestrial ring current, using multi-scale MHD–PIC simulations on HPC. I earned my PhD in Geophysics & Space Physics at UCLA (2022) after a BA in Physics at Oxford, and I build open-source tools for reading, analyzing, and visualizing large simulation datasets. Currently based in Rome.


Projects

pypic

pypic

A Python toolkit for reading, analyzing, and plotting output from particle-in-cell and MHD plasma simulations. It offers a unified reader across formats (iPIC3D, BATSRUS, OpenGGCM) mapped onto a canonical field schema, plus geometry-aware operators and derived plasma quantities.

Python 3.13 · NumPy · xarray · Pydantic

webpic

webpic NEW!

A browser-based 3D viewer and lightweight analyzer for plasma simulation data: volume rendering, oblique slicing, GPU streamlines, and particle clouds at interactive framerates. Schema-compatible with pypic (Zarr / HDF5 / Parquet). Successor to the magviz prototype.

TypeScript · Three.js · WebGPU · early development

magviz

magviz

An earlier interactive web tool for visualizing multi-TB magnetospheric simulation datasets in the browser — the proof of concept that motivated webpic.

Papers

Also in progress: long-period Alfvén waves as field-line-resonance signatures at Saturn (in revision), and a community open-science paper (Corti et al., in prep). Full list on ORCID.


Notes

Occasional notes on plasma physics, computation, and open science — coming soon.


Life

Away from the simulations: cycling, photography, and woodworking — a small exhibit of each, in progress:
