A full classroom economy — a class store, a live stock market, classroom jobs, and twelve game types that keep my room running all year.
LaunchI'm a high school chemistry teacher and computational chemistry PhD who builds the apps, games, and resources I always wished my classroom had.
Every one of these started as a classroom problem. Each card works like an element tile — tap Launch to try the live ones; the rest are still reacting in the lab.

LaunchA mobile-first Lewis structure builder with octet checking, formal charges, and shareable save codes.
LaunchA drag-and-drop Bohr model builder — load the nucleus, stack the shells, drop electrons into place, and copy the atom straight to your clipboard.
LaunchA drag-and-drop particle view diagram builder — size your particles, label their charges, snap them into lattices, pour in a sea of electrons, and copy the diagram to your clipboard.
LaunchA native macOS app that transcribes audio & video entirely on-device — now with speaker identification and full-text search, plus word-level timestamps. Powered by whisper.cpp and Metal; nothing is ever uploaded.
LaunchA swing-physics minigame that teaches ionic, covalent, and metallic bonding — one grapple at a time.
In the lab — coming soonOne first-person drone flight through the whole campus — the trophy commons, the courtyards, and the chem lab where the reactions actually happen. Press play and come on in.
Where I teach
Foothill High School
View my staff page
My full high-school chemistry curriculum lives on a site of its own — interactive notebook pages, slide decks, assignments, labs, and assessments, from 12+ years in the classroom. Free to copy, adapt, and teach.
A full year of free high school chemistry — two complete courses, unit by unit, built in a real classroom and shared with real teachers.
Visit chemlessons.xyzPrint-ready foldables, guided notes, and references for composition-book notebooks.
Google Slides for every lesson, plus interactive HTML decks hosted right there.
Practice sets, station activities, and labs that run on standard classroom gear.
Educators onlyQuizzes, unit tests, and keys — shared privately with verified educators.
I earned my PhD in computational chemistry modeling molecules with code — then discovered the reaction I liked best happens in a classroom. For over twelve years I've taught high school chemistry, and for over eighteen I've been teaching in one form or another.
These days I split my energy between the lab bench and the keyboard: building games that make bonding intuitive, tools that replace clunky software, and systems that make a classroom hum. If it makes chemistry click for a student, it ships.
Ten peer-reviewed papers from my computational chemistry PhD in the Li Group at the University of Washington — density functional theory and real-time dynamics on doped semiconductor quantum dots.
