Dr. Rolland “Rollie” Carlson, CEO of Immunexpress is a veteran of the molecular diagnostics space. With over 25 years of leadership across Abbott, WaferGen, Asuragen, and more, Rollie is now focused on solving one of healthcare’s most urgent crises: Sepsis.

In this episode, we explore why sepsis, despite causing more than 48 million deaths annually remains so poorly understood and misdiagnosed. Rollie breaks down why early detection is so difficult, how gene expression profiling can finally distinguish between infectious and non-infectious inflammation and the real-world barriers to clinical trial design, FDA approval and physician adoption. We also cover military use cases, the lack of gold standards in sepsis diagnostics and what needs to change in how hospitals are incentivised to tackle this condition
