BS Architecture, Georgia Institute of Technology
M Building Science Construction, Auburn

Lindsey Deaton

Advisor: Mark Gillem

Research Interests: Lyndsey is interested in the social implications of architecture at the urban scale. Her dissertation investigates how neoliberal urban policies affect marginalized kid’s social spaces in three global cities (Manila, Hyderabad, and Houston).She is the Associate Director of the Urban Design Lab at the University of Oregon. In practice, she is a senior architect and urban planner at the Urban Collaborative with projects across the United States, the Middle- and FarEast, and Africa. Deaton understands how design can be used to empower communities. Her systems-based planning solutions for sustainable communities were featured in Architect Magazine (2011) and received awards such as the Lafarge Holcim Award for Sustainable Construction (2012), the APA’s Outstanding Collaborative Planning Project (2016), the Mayor’s Choice Award, City of Eugene (2017), and, recently, the Julie and Roxy Dixon Fellowship (2017).

Sean-Michael Kelly (Architecture PhD)

BArch, University of Kansas
MArch, University of Kansas

Sean-Michael Kelly

Advisor: Mark Gillem

Research Interests: Sean Michael’s Ph.D. research centers on the Department of Defense's (DoD) wholesale adoption of antiterrorism design standards across their incredibly diverse portfolio. After a succession of vehicle bombs targeting U.S. government buildings in the 1980s and 1990s, the fear of another attack coupled with the political fear of perceived inaction led the DoD to publish new policy. This policy provides design guidance on everything from project siting to a building’s materiality and interior layout. The questions I ask in my dissertation are how these standards, which aim to counter terrorism, are influencing the urban morphologies and building typologies of U.S.


Manas Murthy (Architecture PhD)

BArch, Guru Gobind Singh Indraprastha University
MA, Sustainable Urbanism, University of Wales
MA, Urban Design, Cardiff University

Manas Murthy

Advisor: Howard Davis

Research Interests: “Instrumentality of Citizen Engagement for Urban Design,” investigating how citizen engagement is ‘performed’ and leveraged by different actors involved in urban development in India. Citizen engagement has seen renewed interest in urban politics, recent urban development projects by more privatized / corporatized delivery mechanisms, activism by the urban middle-class and intellectual groups and a series of ‘grassroots’ initiatives led by diverse professional agencies and non-governmental organizations (NGOs).

MS, Architecture, Kansas State University

Subik Kumar Shrestha

Advisor: Howard Davis

Research Interests: Subik is investigating the urban morphological transformation of Eugene, OR from 1850 to 2018. His specific focus is to analyze, first, the role of specific historical forces in shaping the street configuration and retail business structure and second, the relationship between the two as the city evolved. The research framework is based on fundamental theories/models related to space syntax, Conzenian urban morphology, urban history, and retail business structure. Subik is currently the copy-editor for a series entitled “Reflections on the Built Environment and Associated Practices” (RBEAP) that focuses on issues related to the urbanism of Nepal.

Findings included the role of view, storage, relative size and relationship to outdoor space. Christina is an assistant professor of Health and Wellbeing where her research and teaching focuses on the social, economic and environmental ramifications of housing design, and the manifestation of policy in the creation of the built environment. Her current research investigates social interactions in the shared spaces of Permanent Supportive Housing projects, commonly known as "Housing First.". She is a licensed architect in Washington State and maintains a small practice focusing on low-rise, deep-green residential development.
