Engineering Fellow, Blue Ridge Labs @ Robin Hood

New York, New York, Us

I was one of sixteen individuals selected for the Fellowship at Blue Ridge Labs @ Robin Hood, a tech incubator that brings together mid-career engineers, designers, product managers, and domain experts to research how technology may be able to serve those often overlooked by technology. The 2017 Fellowship focused on low-income older adults and their caregivers and consisted of two phases: a Research phase, in which user and expert interviews were supplemented with desk research, and a Build phase, in which the Fellows built, tested, and refined prototypes of their ideas.During the first phase, I led a research sprint around the topic of elder abuse and investigated other domains such as transportation, holistic health, and nutrition. During the final phase, I formed a team alongside a few others Fellows, and this ultimately grew into Hello Caregiver — a digital tool for caregivers of those with Alzheimer’s or other forms of dementia.
