Former Weather Underground radical Kathy Boudin — who spent 22 years in prison for an armored-car robbery that killed two cops and a Brinks guard — now holds a prestigious adjunct professorship at Columbia University’s School of Social Work, The Post has learned.

Boudin, 69, this year won another academic laurel — being named the Sheinberg Scholar-in-Residence at NYU Law School, where last month she gave a lecture on “the politics of parole and re-entry.”…

Boudin’s status of perp-turned-prof outraged the widow of one of her victims, Brinks guard and dad of three Peter Paige, who was gunned down by her accomplices from the Black Liberation Army on Oct. 20, 1981, in Rockland County.

Boudin acted as a getaway driver in the heist.
