In 2020, she was granted tenure and the title of associate professor.

Research Ailshire's research focuses on how neighborhood environments, including physical and social factors, affect health and aging.

In 2021, Ailshire and USC Leonard Davis School colleague Caleb Finch independently published studies linking air pollution to higher risk of cognitive decline. Later that year, Ailshire and Finch coauthored a research letter that noted how decreasing levels of PM2.5 pollution, particles often found in industrial and automobile exhaust that are small enough to pass through the blood-brain barrier, correlate with reduced risk of cognitive deficits.

A widely publicized February 2025 study Ailshire authored with postdoctoral researcher Eunyoung Choi linked increased days of excess heat with faster biological aging in older adults.
