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.
"An AI computer that works in the cockpit." Orchestr Aerospace builds dual-use avionics, for civilian and defence aviation, from offices in Irvine, California, and Montréal. 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.

The long-term plan is autonomous flight in general aviation, and eventually a high-altitude spaceplane that flies above the Kármán line.

2022 Making quantum mechanics visible: ElectronVisualized runs real DFT and draws electron density in 3D. 2024 Machines that read people: OpticALLY 3D Scan and a flight simulator flown with a brain–computer interface; flight training begins. 2026 In the air: the apps reach the App Store and Google Play, Piper Astrid carries cameras, the team reports from Kennedy Space Center for Artemis II, and Orchestr introduces Jeb's AI. Next: autonomous flight in general aviation, then above the Kármán line.
