Mormino Lab Team

Early Tau accumulation is detected within the medial temporal lobe using Tau PET imaging. 

Elizabeth Mormino, PhD, Principal Investigator

Dr. Beth Mormino completed a PhD in Neuroscience at UC Berkeley in the laboratory of Dr. William Jagust, where she performed some of the initial studies applying Amyloid PET with the tracer PIB to clinically normal older individuals. This initial work provided evidence that the pathophysiological processes of Alzheimer’s disease begin years before clinical symptoms and are associated with subtle changes to brain regions critical for memory.  During her postdoctoral fellowship with Drs. Reisa Sperling and Keith Johnson at Massachusetts General Hospital she used multimodal imaging techniques to understand longitudinal cognitive changes among individuals classified as preclinical AD.  In 2017, Dr. Mormino joined the faculty at Stanford University in the department of Neurology and Neurological Sciences.  Her research program focuses on combining imaging and genetics to predict cognitive trajectories over time, and the integration of novel PET scans to better understand human aging and neurodegenerative diseases.


Kyan Younes, MD
Clinical Assistant Professor, Neurology and Neurological Sciences

Dr. Kyan Younes is a behavioral and cognitive neurologist. He cares for people living with memory, language, executive, visuospatial, behavioral, or psychiatric symptoms. He completed an epilepsy research fellowship at Case Western Reserve University, a neurology residency at the University of Texas Health Science Center in Houston, and a behavioral neurology fellowship at the University of California San Francisco. His recent research projects focused on characterizing patients with right anterior temporal degeneration and on understanding the role of the glymphatic system in neurodegenerative illnesses. His broad focus involves implementing various neuroimaging approaches to achieve early and accurate diagnosis of patients with neurodegenerative diseases.

Christina Young, PhD
Instructor, Neurology & Neurological Sciences

Christina Young received her PhD in Clinical Psychology from Northwestern University in 2018 after completing her clinical internship at the University of Illinois at Chicago where she specialized in Neuropsychology. Her research throughout her graduate training and initial post-doctoral position in the Department of Psychiatry at Stanford focused on using neuroimaging, primarily fMRI, to better understand mood and anxiety disorders. She then joined the Mormino Lab in January 2020 as a postdoctoral fellow and pivoted her research to investigating cognitive decline and development of neuropsychiatric symptoms in neurodegenerative diseases through multimodal imaging approaches.


Cellas Ari'ka Hayes, PhD

Dr. Cellas Hayes received his Ph.D. in Pharmaceutical Sciences with an emphasis in Pharmacology from the University of Mississippi in 2022. His graduate work used transgenic rodent models to study neuroendocrine modulation of ischemic stroke outcomes and learning and memory. Although his doctoral work consisted of basic science approaches, his interest in Alzheimer’s disease, brain aging, and neuroimaging led him to the Mormino laboratory for his postdoctoral training. As a postdoc, Cellas’ work will primarily focus on topographic changes in markers of vascular disease and Alzheimer’s disease (tau PET) to predict cognitive decline and gray matter atrophy in aging. He is also a Stanford Propel Scholar and participated in the Stanford PRISM Program. 

Tammy Tran, PhD

Dr. Tammy Tran is a Postdoctoral Fellow in the Department of Psychology working with Dr. Anthony Wagner and Dr. Elizabeth Mormino on the Stanford Aging and Memory Study. She is currently a Stanford ADRC REC Fellow and is interested in exploring the earliest signs of decline using structural and functional MRI in cognitively normal older adults.  Tammy received her PhD at Johns Hopkins University in 2019 and received training in neuropsychology and high-resolution functional and structural neuroimaging, studying cognitively normal older adults and patients with Alzheimer’s disease.  

Alexandra N. Trelle, PhD

Ali completed her PhD in Psychology at the University of Cambridge, working with Jon Simons and Rik Henson. During her PhD, Ali used behavioral paradigms and functional MRI to characterize age-related changes in memory encoding and retrieval processes. In 2017, Ali joined Stanford University to work with Anthony Wagner and Beth Mormino as lead on the Stanford Aging and Memory Study, a multimodal biomarker study investigating changes in episodic memory function in aging and preclinical Alzheimer's Disease. Her research uses functional MRI, eye-tracking, and CSF and PET biomarkers of AD to identify cognitive and neural signatures that can improve early detection of preclinical AD. Outside of the lab, Ali enjoys yoga, hooping, and eating plants.

Joe Winer, PhD

Joe Winer completed his PhD in Psychology at UC Berkeley working with Matthew Walker and William Jagust. During his PhD, Joe combined objective and subjective sleep assessment with PET imaging to investigate connections between sleep disruption and Alzheimer's disease in the context of healthy aging. In the Mormino Lab, Joe plans to explore how tracking sleep and other factors in everyday life can provide information about brain health and cognitive trajectories in aging and neurodegenerative diseases. 

Graduate Students

Olamide Abiose

Olamide Abiose is a Neuroscience PhD student who joined the Mormino laboratory in December 2019. Her research is focused on the relationship between stress biomarkers and Alzheimer’s disease pathology, as well as brain network topology. She received her bachelor's degree in Philosophy-Neuroscience-Psychology from Washington University in St. Louis in 2014. Afterwards, she received a Master’s in Education from the Harvard Graduate School of Education. Before joining the lab, she worked at the Massachusetts General Hospital (MGH) Center for Law, Brain & Behavior. She was also a member of the Interdisciplinary Affective Science Laboratory led by Dr. Lisa Feldman Barrett and Dr. Karen Quigley at MGH/Northeastern University. Outside of lab, Ola enjoys traveling, exploring new coffee shops, and hosting potlucks.

Clinical Research Coordinators

Jennifer Park

Jen graduated from the University of Southern California in 2019 with a Bachelor of Arts degree in Neuroscience and a minor in Psychology. After graduating college, Jen worked at UC Davis at the Cognitive Electrophysiology and Neuroimaging Lab that seeks to develop methods sensitive to cognitive impairments of neurodegenerative diseases, and then was most recently working on the KHANDLE study that looks to shed light on racial & ethnic differences in aging, cognitive decline and dementia incidence. Jen joined the Mormino and Memory Labs in February 2022, and is looking forward to furthering her interests in the early detection of Alzheimer's Disease & other neurodegenerative diseases and in better understanding the changes that occur in the brain in preclinical AD. In her free time, Jen enjoys exploring new cafes, listening to r&b and jazz music, and spending time with her family.
