The Boss and Our Benevolent Dictator.  


Postdoctoral Fellows


Tengfei Guo

I completed my PhD in Biomedical engineering at Technical University of Munich. I investigated the spatial pattern and temporal pattern of Aβ accumulation in subjects with preclinical and manifest sporadic and autosomal dominant Alzheimer's disease, as measured with amyloid PET.  In the Jagust lab, I will analyze data and obtain data from ongoing studies using PET and MRI in order to test specific hypotheses about aging and the earliest stages of Alzheimer's disease.


Tessa Harrison

I completed my doctoral work with Dr. Susan Bookheimer at UCLA. My focus was on identifying MRI-based neuroimaging markers of genetic risk for Alzheimer's disease in cognitively healthy adults. In the Jagust lab, I will use PET imaging to examine the progression of tau pathology in healthy older adults and its relationship to functional connectivity measures and memory performance. I am also interested in unusually successful cognitive aging trajectories and the avoidance of normal age-related brain atrophy and pathology.

Kaitlin Cassady

I completed my Ph.D. with Dr. Rachael Seidler and Dr. Thad Polk at the University of Michigan. For my dissertation, I used functional MRI and MR spectroscopy to investigate the neural and neurochemical substrates of age-related neural dedifferentiation in the sensorimotor system. My work in the Jagust lab will use fMRI and PET imaging to examine the effects of beta amyloid and tau pathology on age-related neural dedifferentiation and memory.

Graduate Students


Marisa Becerra

I’m a Neuroscience PhD student interested in the pathological changes of the brain during normal aging and disease. My research in the lab will use dynamic contrast-enhanced (DCE) MRI and PET to investigate the relationship between the blood brain barrier breakdown and other Alzheimer’s disease biomarkers, such as amyloid and tau deposition.


Molly Lapoint

I am a neuroscience graduate student interested in how the brain changes during aging and disease. My research focuses on the association between amyloid burden, a hallmark of Alzheimer’s disease, and brain structure and cognitive performance.


Jenna Adams

I'm a Neuroscience PhD student interested in using multimodal imaging techniques to study the neural substrates of aging and memory. My research in the Jagust Lab uses tau-PET and fMRI to investigate how tau spreads through the brain, disrupts functional networks, and leads to episodic memory decline in older adults. 


Joe Winer

I’m a Psychology PhD student interested in the role of sleep in changes to the brain and cognitive function that occur with aging. By combining EEG, PET, and fMRI, I hope to better understand the relationship between pathology, sleep physiology, and cognition.


Visiting Scholars


Bora Yoon

I’m a Korean neurologist interested in subjective cognitive decline (SCD) and early-onset Alzheimer’s disease (EOAD). My research has mainly focused on finding out the relationship between white matter hyperinstensities (WMHs) and cognition, or the impact of WMHs in SCD or EOAD patients. I am really happy to be part of Jagust lab for a year. I hope to better understand and figure out how the PET biomarkers of Alzheimer’s disease are able to predict the clinical course and how they have clinical connection in SCD while I’m here.

I enjoy playing the cello (it’s been temporarily suspended while I’m here), going for a walk and traveling in my free time.

Seunghwan Moon

I’m a nuclear medicine physician from South Korea. I interested in tau pathology as measured with PET imaging. My research focuses on the relationship of tau pathology with Aβ accumulation and clinical outcome in subjects with preclinical Alzheimer's disease. I hope to figure out the specific pattern of the imaging biomarkers of Alzheimer’s disease are able to predict the clinical course.


Senior Staff


Suzanne Baker

Suzanne Baker's primary focus is on the methodology behind PET quantification of all the Jagust Lab data.  Her contributions include pharmacokinetic modeling, correction for motion between transmission/CT and PET scan for attenuation correction, partial volume correction, and preprocessing programming for in-house data as well as multi-site datasets.  In her free time, she enjoys swimming and abalone diving.

Lab manager


Kailin Zhuang

I graduated from University of Rochester with a B.S. in Brain and Cognitive Sciences with a focus in neurobiology and neuropsychology. I’m interested in neuroimaging, cognition, and philosophy of science. Outside of the lab, I enjoy running, reading, traveling, and training for my next Spartan race. 


Research Associates


Kaitlin Swinnerton

I recently graduated from UCLA with a B.S. in Cognitive Science and a minor in Society and Genetics. When not in lab, I can be found either chasing after a frisbee or watching other people chase after a football (or basketball, or baseball, or soccer ball). Life goals include winning a USA Ultimate national championship and setting more life goals.


AJ Whitman

I graduated from Brown with an Sc.B. in Cognitive Science with a focus in Linguistics. I'm interested in working with computers and imaging data to make exciting discoveries about cognition. Hobbies and interests include swing dancing, aerial arts, and rock music. 


Deniz Korman

I recently graduated form Harvey Mudd College with a B.S. in Mathematical and Computational Biology. Im interested in approaching biological questions--particularly those related to cognition--with computational methods. Outside of the lab, I like to spend my time trying new recipes, reading fiction, and going to music shows.


Wesley thomas

I recently graduated from UC Berkeley with a B.A. in psychology. I'm excited to help with and learn more about neuroimaging. I hope to eventually attend medical school and practice psychiatry. Outside of the lab I enjoy reading, meditation, and hiking.


Victoria Tennant

I graduated from UC Berkeley with a B.A. in Psychology. I'm very excited to be a part of the Jagust Lab and to prepare for graduate school! I'm looking forward to learning more about neuroimaging and assisting with PET and MRI scans. When I'm not in the lab I enjoy reading, listening to podcasts, discovering new restaurants, exploring new places, and having a nice cup of coffee.
