R0 Systems makes chemical-free sanitization
equipment for harvested fruits and vegetables.
Grew up on a farm, in a family that has worked in agriculture for generations. Electrical and computer engineering at the University of Washington, with around 3 years across agricultural OEMs and cold plasma for food science, and several publications.

One of the most-cited researchers in cold plasma, with over 14,000 citations and an h-index of 57, and co-editor of the field’s Elsevier reference text. 20+ years across OEMs and agriculture.

Executive Director of Syngenta Foundation India since 2014, and with the IFC. The foundation’s network reaches 2.4 million smallholder farmers across 13 states through 23,000+ agri-entrepreneurs.

Deputy Chief Electrical Engineer at VinFast, Vietnam’s largest electric-vehicle maker, with 9+ years in high-voltage power electronics and battery pack design, previously Head of Electronics at Selex Motors.

12 years at the US FDA, where he founded and directed a division within CDER and oversaw the review of 250+ applications. Now a professor at the University of Maryland and director of its Center for Translational Medicine, with 112 publications.

2,000,000,000tons
of produce is still washed with toxic chemistry.
That leaves chemical residues.
That forms toxic byproducts.
That gets export containers rejected.
That kills workers.
Introducing Plasma-Activated Water.
(or cutely PAW)
R0 builds the equipment that makes it.
A plasma reactor ionizes air into RONS (reactive species).
A microbubble generator dissolves RONS in water, making plasma-activated water.
PAW is antimicrobial. It’s routed into a conveyor with nozzles and sprayed onto produce.
A farmer harvests their produce, throws it onto this conveyor, and collects it on the other end.
The science is published, not just claimed. Three papers across IOP and Elsevier journals cover the reactor, the plasma-activated-water chemistry, and the industrial-scale build.
The core inventions are protected. Two patents, on the plasma reactor and the field-shaping electrode, are filed and pending.
In trials, PAW-washed produce spoiled up to three times slower than chlorine-washed. Less spoilage, less waste, and more sellable yield.
No consumables, no wastewater treatment, no toxic byproducts to dispose of. Up to four times cheaper than industry-standard chemical washing.
