Is Dr. Irwig currently researching PFS?

Since he put out one of the few, but more publicized studies on PFS just last year, I’m curious if he’s doing anything further to advance a treatment or scientific theory. Google searches don’t provide anything he’s done since that study (which was really documenting observed persistent symptoms).

He’s published a few studies, check pubmed.

I do not believe any of his studies delve into the causes of PFS or potential treatments. His work is mostly centered around symptomology and “showing” there is an actual problem. His work is still greatly appreciated by the PFS community as he has given much needed medical/scientific backing to substantiate our issues are in fact real to the world.
