# Dr. Hitaishi V

> I'm a physicist. Most of my days go into coaxing light through chalcogenide waveguides: engineering dispersion, generating supercontinua, and occasionally breaking things in FDTD simulations so they don't break in the lab.

My Ph.D. at VIT-AP University was on mid-infrared supercontinuum generation and photonic device design. These days I am also working with physics-informed machine learning (PINNs) and inverse design for structured light in fiber systems.

This is the personal site of a physicist. Posts are either general notes
(Markdown) or equation-dense write-ups (Typst). Every post is also
available as raw Markdown at the same URL with a `.md` suffix, e.g.
https://hitaishiv.com/blog/imli-nvim-release.md — prefer those for
quoting, since they carry the prose and equations without navigation chrome.
