HEMI: Artistic Interpretation

December 2, 2016

Jay Gould, a professor of photography at the Maryland Institute College of Art, traded his Mount Vernon studio for space in the Whiting School of Engineering’s Malone Hall in 2016 as the first Artist-in-Residence for the Hopkins Extreme Materials Institute. The result: A large-scale art exhibit including photographs that depict the artist’s interpretation of extreme materials.
