She received her BA degree in molecular and cell biology with a neurobiology emphasis from University of California, Berkeley in August 2016.

Devyn Cotter

Research Coordinator

Devyn joined UCSF in June 2017 as a research coordinator in Dr. Joel Kramer’s lab, where she coordinates a study examining the effects of chronic inflammation on brain aging in healthy elderly individuals and in those with mild cognitive impairment.

Deion Cuevas

Staff Research Associate

Deion joined the Seeley Selective Vulnerability Research Lab in 2019 as a research associate and assists with immunohistochemistry, cryosectioning and the brain bank for various projects. He received his BS degree in biology and BA degree in anthropology at the University of California, San Diego. During his time there, he was a lab assistant in the Lab for Human Comparative Neuroanatomy where he studied neurodevelopmental disorders. He focused on the GABAergic system within the striatum in postmortem human individuals with Williams Syndrome.

Mary De May, MD
