I study modern and contemporary urban history and theory with a focus on debates around ideas of difference within the built environment. My dissertation investigates the emergence of queer urbanism in the Bay Area during three overlapping periods: gay liberation and the beginning of the transgender movement (1966-1983), the response to HIV/AIDS (1981-2014), and queer politics (1990-today). I investigate the physical, social and administrative infrastructures associated with queer urbanism, and the corresponding distinct articulations of sexual citizenship through multiple community-specific demands, related obligations, and affiliations. In addition to spatial manifestations of sexual citizenship, I study the contingent and changing aesthetics of queer spaces in the Bay Area through visual anthropology methods.
