An adjunct college professor has been busted for allegedly sending nude photographs to an undercover cop posing as a teenage girl and arranging for a tryst with her in Queens.

Igor Sorkin, 31, of Brooklyn, sent the pictures, including Web cam images of his genitals, to the 14-year-old “girl” from Oct. 5 until Jan. 25, said DA Richard Brown.

He was busted Tuesday night at a pre-arranged meeting point.

Sorkin works as an adjunct professor of economics at Barnard College, Pace University and Hunter College in Manhattan, and at Brooklyn College and St. Joseph’s College in Brooklyn.
