Our team

ChloBis Water was founded by two Ph.D. researchers and a chemistry professor working together at UW-Madison. Over the last four years, we have been working to demonstrate technology proof-of-concept and are motivated and excited to bring this technology to market. We are passionate about using innovative science to improve affordable access to fresh water and have created a supportive and collaborative environment that encourages the generation of new and creative ideas to solve problems.
