Research

I am studying, designing, and developing accessibile technologies that best represent older age and disability. Read below for a list of active research projects.

Online Engagement + New Forms of Social Support

Some people cannot easily access computers, smartphones, and traditional forms of internet access everyday, and others may not want to. Yet, internet access does provide resources like social support and can affect emotional well-being. This is particularly important for aging populations who are at higher risk for isolation and depression. My prior work has investigated how older adults currently engage online to inform how to better engage those who do not participate. Rather than force people to use computers and smartphones, I study how we can use technologies people are familiar with and interested in using by mostly studying how landline phones and smart speakers can be leveraged as a source of social support.

Accessible Voice Interfaces

Voice interfaces like voice assistants can be used as a more accessible means for accessing resources like critical health information online or social support, particularly for people who face challenges using smartphones or computers. I study how we can leverage voice interfaces as a tool to facilitate easier information access and meaningful social support.

Designing Accessible AI-Powered Environments

Autonomous and automated transportation has the potential to improve social and economic mobility for people with disabilities. However, such forms of AI-powered transportation raise questions around transparency, trust, control, and fairness. I studied how one community, blind and low vision people, perceive these challenges and propose multimodal design interventions. Relevant papers:
