Solo exhibition at Dallas Contemporary

'Her Marks, a Measure' is an exhibition exploring the role women's labour in astronomy and ballistics. In both these fields women made significant contributions to observation, data collection, and computation. Alongside the film Between the Bullet and the Hole, the show features Her Luminous Distance, a slide-based installation which uses a Blink Comparator, a device used by astronomers to detect small pattern differences between photographic plates by alternately switching between images, blinking back and forth between the two. The PROBLICOM (Projector Blink Comparator) was invented by amateur astronomer Ben Mayer, using two juxtaposed slide projectors and a rotating disc, alternately occulting the images at a stroboscopic pace. The accompanying binaural soundtrack is a pulsing rhythmic drone which plays on the perception of patterns.

Developed from research on the pioneering deaf astronomer Henrietta Swan Leavitt (1868-1921), the project attends to the lesser known women who contributed to important astronomical discoveries, in particular the women known as 'Human Computers' at Harvard, who were engaged in painstaking astronomical observation and classification. In her extensive studies of Variable Stars, Leavitt discovered the period-luminosity relation, which ultimately helped calibrate a method to determine the size of the universe. The blinking slide sequence includes images drawn from Leavitt's original annotated photographic plates of Variable stars, archival images from the Human Computers' workplace, and a series of over 20 images of craters on the moon named after women astronomers. The Leavitt Crater is on the far side of the moon, and is also in honour of deaf scientists.

In addition to the film and slide-based installation the exhibition features circular lenticular prints.
