"This is the worst time to be a scientist in the USA in 50 years."
Rohn's in charge of the Alzheimer's research lab at Boise State University, a lab that depends on funding from the National Institutes of Health, funding that will almost certainly end with the looming federal budget cuts.
"This particular grant is several hundreds of thousands of dollars over three years," Rohn said. "You just can't have a bake sale to recoup those monies."
And without that grant, Rohn's research cannot go forward.
"You basically have to shutter the doors," he said. "For me, that's a realistic possibility."
It's a big personal blow for Rohn, and the undergraduate and graduate students who work with him in developing more effective drugs for Alzheimer's treatment.
But it's even more devastating for the estimated five million people who suffer from Alzheimer's in the United States, a number that's expected to triple within the next 40 years.
And it's not just the Alzheimer's lab that will be impacted, it's estimated the budget cuts will eliminate some $12 billion from federally-funded research labs around the country.
