He started by drawing what nobody can see: electron clouds, orbitals and density maps, so that a student could look at quantum mechanics instead of just reading about it. One of those density maps ended up on the cover of a Nobel laureate’s biography. Today he builds computers that ride in the cockpit and look out of the window.
Now | since September 2025
John founded Orchestr Aerospace in September 2025 and runs it as CEO and technical founder. The company builds dual-use avionics, for civilian and defence aviation, from offices in Irvine, California, and Montréal.
“An AI computer that works in the cockpit.”
The thread from his physics work is direct. A density map is a computer showing a person what it knows about a scene they cannot see. A cockpit computer does the same with traffic, terrain and weather. Orchestr’s research goes one step further: working out where the aircraft is from what its cameras see, so navigation keeps working when GPS is jammed or spoofed.

A copilot you can talk to, trained on your own aircraft’s handbook. It answers from the documents it was given; the pilot in command stays responsible.

The company aircraft, flown as a sensor platform and a testbed for ADS-B and computer-vision traffic detection.
The long-term plan is autonomous flight in general aviation, and eventually a high-altitude spaceplane that flies above the Kármán line.
The story so far
One line, six stations. Each stop taught him something the next one needed.
2022
In 2022 he entered the Breakthrough Junior Challenge with “Schrödinger’s Equation & DFT in 90 Seconds”, a 90-second explainer of the Schrödinger equation and density functional theory. The same year he started ElectronVisualized, a web app that runs real DFT calculations and draws the resulting electron density and molecular orbitals in 3D. It later grew iOS, macOS and visionOS versions.
Loading the 3D model
June 2023
His Swift Student Challenge app playground turned the Heisenberg uncertainty principle into something you could play with, and it won. MobileSyrup named him one of six Canadian winners. Apple invited him to Apple Park for WWDC23, where he met engineers from the Vision Pro team, iJustine and MKBHD, then wrote it all up on Medium and YouTube. The playground grew into Atomizer AR, an augmented-reality atom and orbital viewer.


Seoul
A summer research internship at Seoul National University turned side projects into tools. He built electronvisual.org, brought Atomizer AR up to industry standard, and developed LCBC Dock, now MolDock, which pulls fragmented protein–ligand docking tools into one app on the App Store and Google Play. His DFT density map of the hydrogen molecule went on to become the cover art of Sir David Clary’s biography of Walter Kohn.
2024
The questions moved from atoms to people. OpticALLY 3D Scan builds a 3D model of a head from nothing but an iPhone’s TrueDepth camera. He wired an OpenBCI brain–computer interface into a flight simulator and flew with it; the clip drew 156 reactions on LinkedIn. Around the same time he started flight training.

2025
From August to December 2025 he worked as a software engineer at Reach, building a TrueDepth face-scanning app with the company’s CEO, Drew Shepard. In September he founded Orchestr Aerospace. By December he was at UCLA, telling the Global Entrepreneurship Society why he wants to replace the autopilot with vision-based AI.

2026
Orchestr’s apps reached the App Store and Google Play, the company aircraft Piper Astrid started carrying cameras, and the team reported from Kennedy Space Center for the Artemis II launch. In October 2026 Orchestr introduced Jeb’s AI to its pilot audience.

Autonomous flight in general aviation, then above the Kármán line.
Collaboration | Sir David Clary FRS
John collaborated with the Oxford chemist Sir David Clary FRS on his biography of Walter Kohn, the physicist behind density functional theory.

Walter Kohn: From Kindertransport and Internment to DFT and the Nobel Prize
David C. Clary | World Scientific | 2024
The front cover is built on an electron density map of the hydrogen molecule that John calculated with density functional theory, the theory Kohn created. The book’s preface credits it:

Preface, World Scientific
Walter Kohn left Vienna as a boy on the Kindertransport, was interned as an “enemy alien” in Britain and Canada, and went on to develop density functional theory, the method that lets chemists compute the electronic structure of molecules and materials. It earned him the 1998 Nobel Prize in Chemistry, shared with John Pople. Clary’s book follows that whole arc, from refugee to laureate.
Sir David Clary FRS is a theoretical chemist and Professor of Chemistry at the University of Oxford. He was President of Magdalen College, Oxford, from 2005 to 2020, and the first Chief Scientific Adviser to the UK Foreign and Commonwealth Office, from 2009 to 2013.

Talks
Global Entrepreneurship Society at UCLA | December 2025
John spoke to UCLA’s Global Entrepreneurship Society about building Orchestr. The talk covered four ideas.
01
Letting a pilot work the cockpit displays without taking a hand off the controls.
02
Aircraft that understand the scene outside, not only the numbers from their instruments.
03
Ship in public, post the demos, and let the work make the case.
04
“I hate competition; I want to dominate.”

“the Global Entrepreneurship Society at UCLA had the pleasure of hosting John Seong”
