Earlier this week I spent a cool, wet morning on the lawn behind Pine Intermediate School in Ohio, where a narrow stream winds through the grass on its way to Lake Erie. STEM teacher Shari Insley had invited me to show her fifth graders how real‑time data can transform abstract water‑quality lessons into something they can see—and feel—they have […]

With support from the Department of Education, GaiaXus has spent the last few years developing affordable, accurate, and versatile equipment for water quality monitoring in collaboration with teachers and citizen scientists. The Water Guardians have now touched ecosystems all over the United States, and abroad in Kenya and the Netherlands, leaving us wondering: how can

On May 13, 2025, I had the privilege of pitching our GaiaXus Water Guardian at Salisbury University’s 24th Philip E. and Carole R. Ratcliffe Foundation Shore Hatchery Entrepreneurship Competition. After an inspiring, high‑energy day, the judges awarded us a $5,000 prize—exactly the boost we need as we move from small‑batch builds to full production scale. Why does this check—and the program behind it—matter? Since

Freshwater salinization from road salt is a well-documented phenomenon—but its ecological consequences may be evolving faster than we thought. During a routine field validation of our GaiaXus WaterGuardian system at Black Hill Regional Park, we towed a conductivity and temperature probe behind a recreational kayak to assess spatial patterns in salt distribution. The system performed

Last week, we had the privilege of delivering our Water Guardians to Ohio, equipping and training 14 schools with our water quality monitoring and education system. Thanks to the generous support of the Leonard Gelfand STEM Center at Case Western Reserve University, middle, high, and elementary schools across the region now have access to tools

Winter storms don’t just bring snow—they send road salt into streams, disrupting freshwater ecosystems. Salt is necessary for road safety, but once it washes into waterways, it can dramatically alter water chemistry, harming aquatic life. Until now, capturing these rapid changes as they happen has been challenging. We developed the GaiaXus Water Guardian to change

I had the incredible opportunity to attend the 2024 Sea Grant Marine Debris Symposium at the NOAA Research Offices in Silver Spring, Maryland. It was an inspiring event, and I’m genuinely grateful to have connected with experts, educators, and researchers—all united by their passion for protecting our waterways. My Takeaways Marine Debris: It’s staggering how

We are excited to announce the start of our collaboration with the University of Maryland Baltimore Campus. Dr Govind Rao’s team at The Center for Advanced Sensor Technology (CAST) at UMBC promotes the development of sensors for biomedical, bioprocess, environmental, and homeland defense applications. The collaboration is funded by the MIPS program for the duration
