Research Interests

• Jason Hellmann Lab

We aim to identify basic cellular mechanisms that intrinsically regulate inflammatory tone and duration to garner new knowledge for the better treatment of chronic diseases with an inflammatory etiology. Our research is focused on uncovering novel mechanisms that control bioactive lipid mediator biosynthesis and inflammation resolution.
