What this research studies

The team focuses on the flu virus polymerase, the molecular machine that copies viral RNA and drives mutations that create new strains. They will combine evolutionary analyses of viral sequences with lab tests that measure mutation rates and with deep mutational scanning to see which polymerase changes are possible. Computer-based molecular dynamics and in vitro polymerase assays will help link specific genetic changes to how the enzyme works. Findings aim to show which polymerase changes are allowed or blocked, helping predict how new flu variants might arise.

Who could benefit from this research

Good fit: People recently infected with influenza who can provide nasal or throat swabs or other virus-containing samples, or clinical sites that collect such samples, would be the most relevant contributors.

Not a fit: People without current influenza infection or with unrelated health issues are unlikely to receive direct benefits from this project.

Why it matters

Potential benefit: If successful, this work could help researchers predict dangerous flu variants and guide better vaccine and antiviral design.

How similar studies have performed: Related lab and computational approaches have been used successfully to map viral mutations before, and this project builds on those methods.
