Our Team

Diana Guzmán (she/her) is a Clinical Research Coordinator within the ADAPT imaging lab (formerly known as the Kreisl lab). She graduated from Gettysburg College in 2020 with a bachelor's degree in health science and peace and justice studies. Diana works to ensure regulatory compliance of all research conducted within the lab, which includes corresponding with the Institutional Review Board (IRB), the FDA, and the Joint Radiation Safety Committee (JRSC). Diana also conducts research participant study appointments, including administering neuropsychological test batteries and overseeing neuroimaging visits. Diana is working on her own project titled, "Moderate alcohol use, total brain volume, and white matter hyperintensities among racially and ethnically diverse middle-aged adults" which she presented at AAIC 2023.  She is currently a student in the premedical post-baccalaureate program at Columbia University and will be applying to medical school.

Hannah Houlihan (she/her) is a research assistant in the ADAPT imaging lab. She graduated from the University of Delaware in 2022 with a major in neuroscience and minor in cognitive science. Hannah focuses on running participant visits as well as image data analysis. Hannah hopes to continue onto a neuroscience PhD program in the future. In her free time, she enjoys listening to music, going to the beach, and going hiking.

Daniel Talmasov is a physician-neuroscientist with dual training in neurology and psychiatry. Dr. Talmasov’s research applies core neurologic principles to understand how distinct and stereotyped clusters of psychiatric symptoms emerge from the interactions of specific disease processes and neuroanatomic networks subserving human behavior. Dr. Talmasov’s work in the ADAPT lab aims to clarify how clinical heterogeneity in the psychiatric manifestations of Alzheimer’s disease relates to the relative burdens of proteinopathy, atrophy, and inflammation in the brains of affected individuals.

Dr. Talmasov trained in psychiatry at the Brigham and Women’s Hospital / Harvard Medical School program, and in Neurology at the NYU Grossman School of Medicine. Dr. Talmasov is presently a clinical fellow in Columbia’s Behavioral Neurology and Neuropsychiatry fellowship program and concurrently a T32 research fellow in late-life neuropsychiatric disorders.
