Understanding energy use and power relationships in low-income communities
The relationship between feedback technologies and energy-conservation behaviors has become an increasingly important focus in the field of human-computer interaction. However, few studies have explored this phenomenon among low-income and renter households. My early dissertation work bridges this gap via qualitative studies of low-income households across Eastern, NC and Pittsburgh, PA. Our studies of low-income households show that comparison across households can have an important impact on how energy is used (or saved). These studies also reveal conflict between various internal and external stakeholders such as family members and landlords. My dissertation work investigates this conflict and identifies factors such as social engagement and social sharing as potential solutions. My final dissertation work leverages existing energy-monitoring technology along with customized software to better understand the impact of engagement around social sharing and community energy monitoring. I conducted a long-term field study across 15 renter households in Pittsburgh, PA for 4-10 months.

Post-sustainability and Resilience
I attended a workshop to consider ways that we can evolve a research agenda in HCI about how to move sustainable HCI to the next level — one that goes beyond persuasion, adopts a deeper perspective on sustainability, and supports and prepares for transformations induced by large scale social and environmental change. I was particularly interested in resilience, or building cohesive communities: “Stronger local communities are more resilient to change and shocks; people are able to act together collectively in response to challenges, and strongly affected individuals are more likely to find support. Can online social media, mobile devices etc be used in such a way as to build more cohesive local communities? Can they help create support networks that exist beyond the virtual? Or do they naturally result in reduced cohesion?”

Motivating prosocial behaviors
I am deeply committed to solving real-world problems using human-computer interaction (HCI) research and ubiquitous technology innovations. In collaboration with colleagues, I have used techniques from social and behavioral sciences and human-centered design to create interfaces aimed toward increasing pro-social behaviors.

I look forward to building upon this work, conducting interdisciplinary research, and understanding how social, ubiquitous, and information and communication technologies can be used to solve society’s most critical problems.
