Our Mission

Investigating Health Disparities in Aging Populations: Unraveling the Complexities of Multimorbidity

Dr. Bishop's research delves into the progression of complex age-related health conditions while aiming to pinpoint risk and protective factors that contribute to health disparities among aging populations. Presently, their work centers on analyzing population trends in multimorbidity, with a significant focus on exploring the interconnectedness between cognitive decline, progressive physical disablement, and multimorbidity. They have previously focused on identifying potentially modifiable points of intervention in the progression of chronic diseases, particularly examining food insecurity and dietary intake. In their non-academic professional roles, they have led multidisciplinary teams, resulting in impactful applied research in population health and education. Their primary objective is to contribute to research that informs clinical practice and policy development by identifying emerging health trends within the expanding and increasingly diverse aging population.

Identifying cohort trends in multimorbidity by birthplace, race/ethnicity, and intersecting social factors

This project 1) examines whether the health advantages observed among non-native adults may be masking even greater multimorbidity risk among U.S.-born adults, and 2) will identify intersectional drivers of racial/ethnic disparities in multimorbidity using a life course perspective.

The role of multimorbidity in the progression of cognitive decline and onset of dementia among Mexican-American and Mexican older adults

This project uses the Health and Retirement Study (HRS) and Mexican Health and Aging Study (MHAS) to examine how immigration status influences the association between multimorbidity and cognitive outcomes among Mexican-American and Mexican older adults.

Emerging cohort disparities in multimorbidity in U.S. adults entering early older adulthood

This project uses representative data from the Panel Study of Income Dynamics to model cohort trends in multimorbidity from 1999–2019 in adults aged 50 and older.  

Exploring perceived limitations to normal daily activities due to chronic conditions: A person-centered approach to measuring severity of multimorbidity

Data from the Panel Study of Income Dynamics (2005–2021) are used to investigate self-reported limitations in daily activities resulting from multiple chronic conditions.

Health and aging among U.S. agricultural workers

This project examines trends in the age distribution and burden of chronic conditions among older farmworkers in the National Agricultural Workers Survey.
