I am studying, designing, and developing accessibile technologies that help aging populations and people with vision impairments engage in online communities and with resources in meaningful ways. 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.

Transportation as a Resource

Transportation is key for social and economic mobility, but can be challenging for people with disabilities such as vision loss or mobility challenges to access. I am interested in understanding how emerging forms of transportation (i.e. autonomous vehicles and ridesharing) can be more accessible to communities. Relevant papers:

Accessible Voice Interfaces

Voice interfaces like voice assistants can be used as a more accessible means for accessing resources like information online or social support, particularly for people who face challenges using smartphones or computers. Yet, forms of information seeking helps people access critical resources that can sustain and improve well-being. I study how we can leverage voice interfaces as a tool to facilitate easier information access.
