Ostendarp has had over 33 solo exhibitions and participated in over 170 group shows internationally. According to Howard Halle, “Ostendarp was part of a wave of Yale trained painters during the early-to-mid-’90s, who took a dyspeptic approach to reviving various art-historical genres.”
The artist is a founding member of the Elizabeth Dee Gallery. Recent exhibitions include: Blanks at Elizabeth Dee, New York; Everything Falls Faster than an Anvil at Pace Gallery, London; and Pop Abstractions at Garth Greenan Gallery. He has been a professor, teaching at several schools, including The Cooper Union, prior to his 17 years at Cornell. Ostendarp received his B.F.A. from Boston University and his M.F.A. from Yale University. He currently directs the Graduate Program of Art at Cornell University.
