The city is a many-layered ecosystem, but much of it remains hidden from casual observation. My work seeks out discontinuities, fault lines, and interstitial spaces, all the places where the unseen city springs unexpectedly into view and deep interactions between architecture, environment, history, and socioeconomic systems may be more readily observed. Such places may include shifting or climate-change-destabilized coastlines, disused infrastructure, intentionally concealed seats of power and control, and even the spontaneous wild refuge of an abandoned lot. The same forces and complexly mixed meanings can be observed in any natural or unnatural landscape upon which humans have exerted their influence, but the density of urban zones has an especially concentrating and clarifying effect.
