As the other commenter noted, I think there are several folks at Mason who are Austrian leaning. Don Boudreaux was someone whose writing I followed back in the late 20-aughts, I'm sure he's still doing work.
George Mason very much the case of the exception underlining the rule though: it's the go to place for Austrian economics, has massive Koch Foundation endowments to encourage it to emphasis Austrian economics in its teaching, and yet it's still populated by people who are somewhat sympathetic to Austrian ideas that write "why I am not an Austrian Economist" essays and has a pretty non-Austrian sounding syllabus.
I think the status of Austrian economics in academia is best represented by the Mises Foundation's short list of best places to study Austrian economics, which concedes "some only have a sympathetic faculty member" and warns that some places have a lot of mathematics...
Their list is extremely outdated, and represents a fairly narrow view of Austrians (most modern Austrians not affiliated with LvMI, which is the majority of them, do quite a bit of quantitative work where it's warranted).
GMU is still the center (it's an Austrian fusion, but there's still a LOT of Austrian stuff -- Bryan Caplan is the exception rather than the rule), but Texas Tech, Troy, SJSU, FSU, and a number of others have heavy representation. I can think of at least 25 universities off the top of my head with at least one open Austrian on faculty. And yes, syllabi aren't just Austrian stuff -- even Austrians want you to learn Economics, not just what Mises said about Economics.
