LCLS-II SRF Engineer/Physicist at SLAC National Accelerator Laboratory. I build and own the production Python that operators use to run a superconducting linear accelerator.
Most of my work lives in the slaclab organization, not on this
profile — the repositories here are mostly my forks of it.
- slaclab/sc_linac_physics — I created this project and author most of its commits. Operator displays, analysis tools, and CLI for the LCLS-II superconducting linac: 296 superconducting RF cavities today, expanding to 480. ~100 automated releases, and an 80% branch-coverage gate enforced on every pull request.
- slaclab/lcls-tools — SLAC's shared Python library for accelerator controls and data analysis. Top contributor of 15, over five years.
- Auto setup — hierarchical automation of RF cavity characterization, from a single cavity up to
the whole machine. Replaced a multi-hour manual procedure with an automated one: twenty minutes
at the time of the SLAC Technology Excellence Award it won, and five minutes now. Originally
slaclab/srf_auto_setup, since migrated into
sc_linac_physicsand substantially improved — it's still the tool operators use.
First author on Measuring Q₀ in LCLS-II Cryomodules Using Helium Liquid Level (SRF'23) — a measurement method developed at Jefferson Lab during cryomodule acceptance testing, then used in the tunnel at SLAC. Co-author on three further SRF papers.
Built with Claude Code. I bring the requirements, the domain, and the testing; the implementation is agent-written.
- candy-dance-case-study — how the CAN.dy membership platform works and why: bylaws enforced as Postgres constraints, triggers and RLS policies, built in five days against a real deadline. Includes what the approach cost and a straight account of which decisions were mine and which were Claude's. Application source is private; this is the write-up.
- static-apps — a monorepo of small personal web apps (live) under one constraint: no build step, no bundler, nothing from npm at runtime. A piano sight-reading trainer, an algae bloom tracker, and a Hayward election results tracker.
I mentor a summer intern every year (DOE SULI, SJSU SPARK, Foothill College) and have volunteered with SAGE Camp — Science Accelerating Girls' Engagement in STEM — since 2020.
