About

Shana L. McDevitt is a research scientist whose work has been pivotal in advancing high-throughput molecular diagnostics for public health surveillance. Her primary research areas include viral RNA extraction, saliva-based testing, and the automation of laboratory workflows for infectious disease monitoring. McDevitt’s most significant contribution came during the COVID-19 pandemic, where she developed and validated a robotic RNA extraction protocol specifically designed for saliva samples. This innovation enabled large-scale, asymptomatic surveillance by eliminating the need for more invasive nasal swabs and streamlining the direct-to-RT-qPCR process. Her seminal 2021 paper on this method has garnered 18 citations, underscoring its practical impact on pandemic response efforts. By demonstrating that saliva is a reliable and scalable specimen type for detecting SARS-CoV-2 RNA, McDevitt helped public health agencies expand testing capacity in community settings. Her work not only addressed an urgent global health crisis but also set a precedent for using automated systems in future outbreak surveillance. McDevitt’s achievements highlight her role in bridging the gap between laboratory innovation and real-world application, making her a key figure in the evolution of molecular epidemiology.
