I had two grant proposals up for review in the NIH Bacterial Virulence (BV) study section. It was canceled without notice this morning.
Without those grants, my lab must close within a year.
And so the purge of scientific research in the US continues

My latest publication is out. I published an article back in 2007 looking at the resurgence HIV denial w/ the rise of the internet & online advocacy. Sadly that's had a bit of a resurgence w/ RFK Jr & others, so I updated the piece with info from the last 15 years. link.springer.com/article/10.1...

Though scientific consensus regarding HIV causation of AIDS was reached decades ago, denial of this conclusion remains. The popularity of such denial has waxed and waned over the years, ebbing as evid...
