David Perry, MD
Principal Investigator
Dr. Perry graduated from medical school at Georgetown University in Washington, DC. He completed an internship in internal medicine and residency in neurology at the Mayo Clinic in Rochester, Minnesota where he also researched obsessive-compulsive features in dementia. He is an Associate Professor of Neurology at the Memory and Aging Center and participates in the evaluation and treatment of patients in the MAC clinic. His research focuses on two topics: 1) understanding the impact of neurodegenerative illness and mood disorders on reward processing, and 2) identifying clinical and neuroimaging features that improve the certainty of the clinical diagnosis and the prediction of the pathological diagnosis in neurodegenerative disease.

Sean Coulborn, PhD
Postdoctoral Fellow
Sean Coulborn is a postdoctoral researcher at the UCSF Memory and Aging Center, mentored by Dr. David Perry. His research is centered around enhancing the accuracy of clinical diagnoses and forecasting pathological diagnoses in neurodegenerative diseases. Before joining UCSF, Sean held a postdoctoral position at UC Berkeley, where his research concentrated on unraveling the neural mechanisms underlying decision-making. He linked abnormalities in these processes to dimensional measures of psychopathology. Sean earned his PhD in Psychology from the University of Birmingham, UK, where his research investigated the neural correlates of consciousness using multimodal imaging techniques including fMRI and tDCS.

Ashlin Roy
Data Analyst
Ashlin earned his Bachelor of Science in psychology at the University of Oregon in 2016. He joined the Perry Lab in 2018, where he works as the lab’s data analyst. He also works in the CAN Lab at UCSF's Memory and Aging Center directed by Dr. Virginia Sturm. In his current project in the Perry Lab, he investigates the shared behavioral profiles in frontotemporal dementia-spectrum and Alzheimer’s disease-related syndromes and seeks to determine their underlying neural correlates.

Meghan Johnson
Research Coordinator
Meghan graduated from UC Irvine in June 2025, where she earned her Bachelors of Science in Psychology. During her time at UC Irvine, she worked with Dr. Aaron Bornstein investigating decision-making and memory in older adults. Following this, she joined the Perry lab as an Assistant Clinical Research Coordinator. She is interested in further investigating decision-making and reward processing in neurodegenerative disease.
