Abstract
Drift Alignment is an ongoing body of work that engages the complex and contested history of the US-Mexico border through the practices of astrophotography and celestial navigation. My primary motivation for this work has been an examination of both the material and ideological conditions that led to the formation of the border, as well as its lasting relationship with colonialism, and the tragic consequences of immigration enforcement. Throughout the series, works oscillate between attempts at precision and its inverse — both subjective experience and mathematical error — to build a more poetic understanding of the region and its inhabitants.
Photographic and video works in the series are based on a combination of archival information related to the border surveys during the mid-nineteenth century, eighteenth century Spanish missionary activity, and contemporary GIS data for migrant deaths in southern Arizona. Other work was produced during extended visits to sites that are tied to my past and present connection with the border, as well as historically significant locations that point to the shifting ways of perceiving and understanding of the lands of the American southwest.

O’Brien’s artistic practice draws from lived experience to examine the organization and perception of physical space — especially as it relates to landscape and the built environment. His work is informed by the history and symbolic potential of materials, as well as the shifting incarnations of the photographic image. Works range from experimental publications, to photographs, video, and installation. He has exhibited widely, including at the Houston Center for Photography, The Center for Fine Art Photography in Fort Collins, Colorado, the West Gallery at California State University Northridge, and the Art Museum of Northern Illinois University, among others. In 2021 O’Brien was named a Tennessee Arts Commission Individual Artist Fellow.
