Research Overview

My dissertation examined the link between social interaction and neurocognitive disorders. Among the 5.4 million Americans with Alzheimer’s disease, over half live in the community among caregivers whose unpaid assistance constitutes their primary form of care. In a series of projects, I study the caregiver support networks of new patients coping with the onset of Alzheimer's disease. I examine how social inequalities affect the availability of caregiver support, how support evolves during the course of care, and whether or not support moderates loss of cognitive function. This research contributes to community-based care initiatives through identifying how, when, and why caregivers are effective intervention partners for medical professionals. I presented a portion of my work in this area at the 2018 Duke Social Networks and Health Workshop - the video of that presentation is available on YouTube.

A second line of research applies network analysis to health care delivery. I use a dataset of 18 million health insurance claims records to construct a national map of patient-sharing among physicians treating patients for Alzheimer’s disease. I then examine the relationship between connectedness in the physician network and the timing and costs of care received by patients. This research uses network analysis and big data to develop a network-based conceptualization of coordinated care between health care providers. I illustrate how health inequalities experienced by disadvantaged populations may emerge from the hidden architecture of the medical system itself. I previously organized a session on Health Care Provider Networks at Sunbelt 2018, and will organize a follow-up session at Sunbelt 2019.
