Epilepsy and Cognitive Health Lab
Emily Johnson · Baltimore, Maryland
Johns Hopkins University · Neuroscience
Research focus
Dr. Emily Johnson's research lab at Johns Hopkins University focuses on understanding late-onset epilepsy, particularly how epigenetic factors and chronic health conditions contribute to cognitive decline in older adults. The lab explores the relationship between environmental exposure, genetic markers, and cognitive performance to aid dementia prevention strategies. This work is especially relevant for the over 250,000 older adults in the U.S. suffering from this condition.

Career totals from OpenAlex, compared against labs that share a department. Position on each rail is this lab's rank, not its distance from the top: a department runs from one paper to tens of thousands, so rank is the only comparison that stays readable across it.
