Indiana U start-up develops novel method for assessing chemical risks

An Indiana University (IU) startup has developed a technology that could help federal and international organizations assess the risk of chemicals in food, pharmaceuticals, pesticides and other products.

Launched by assistant professor Kan Shao, Dream Tech LLC uses an estimation system for the dose-response assessment phase, which address a chemical’s toxicity. Shao says his technology is a response to drawbacks associated with traditional methods to conduct quantitative risk assessments.

“Regulatory agencies face two major challenges,” he comments. “The first is the gap between the speed of conducting assessments and the speed of new chemicals being developed. The second is determining how regulatory risk-assessment results can better support benefit-cost analysis-based decision-making.

“Dream Tech can improve the dose-responsive modeling approaches to make the assessment more efficient and effective,” says Shao, adding that his system “also provides probabilistic estimates for the most important quantities, which cannot be achieved by current dose-response modeling systems.”

With help from the university’s tech transfer arm, the IU Innovation and Commercialization Office, Shao protected his invention and licensed it to Dream Tech. He is now seeking investments to support his start-up’s growth.

“The next milestones include the acceptance of our system as an alternative dose-response modeling system to support regulatory risk assessments and to engage external sources for financial support,” Shao says.
