My research examines the role of neurochemistry in shaping individual differences in cognition. I couple advanced fMRI approaches with PET dopamine measures to establish how dopamine influences activity within local circuits and large-scale functional networks. My research in aging focuses on defining how decline in medial temporal lobe memory systems and dopaminergic reward systems interact to alter memory and decision making.
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.
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.
I received my Ph.D. in Psychological & Brain Sciences at Johns Hopkins University in the Translational Neurobiology Lab under the direction of Dr. Michael Yassa. I examined the emotional modulation of episodic memory and translational applications to aging and depression-related cognitive impairment using a novel emotional memory task along with high-resolution fMRI.
My research in the Jagust Lab focuses on the influence of tau pathology on memory consolidation in cognitively normal aging. I utilize high-resolution fMRI methods in combination with tau PET imaging to elucidate tau’s effects on hippocampal subfield functioning.
I am a nuclear medicine physician passionate about the study of the brain. After completing my medical studies at the University of Rome "Sapienza," I started my residency program and learned how to interpret clinical PET and nuclear medicine scans. During my residency I was a visiting researcher at the Department of Clinical Neuroscience at the Karolinska Institute in Stockholm, Sweden, where my research focused on the clinical application of a novel PET radiopharmaceutical (18F-FE-PE2I) to image the dopamine transporter in Parkinson's disease patients. After completing my training in Italy I moved to the US to work as a postdoc in the nuclear medicine division at Stanford University, focusing on PET/MRI studies in the field of oncology. In the Jagust Lab, I will be focusing on PET biomarkers of Alzheimer's disease.
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.
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.

I’m a PhD candidate in the Neuroscience Program at UC Berkeley. Employing multimodal brain imaging of age-/disease-related perturbations, my research aims to uncover (ideally fundamental) links between brain networks, cognition, and pathology.
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.
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.

Kris is a radiologist specialist working to collect PET data.
I graduated from UC Berkeley in 2016 with a B.A. in psychology. My interest in the study of aging and dementia began as a student in Dr. Jagust's course, The Aging Human Brain, and I am thrilled to now be part of the lab. In the future, I hope to pursue a PhD in clinical psychology. When not in the lab, I enjoy playing soccer, running, wandering around Moe's Books, and eating at Cheese Board.
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.
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.
I recently graduated from UC Davis with a B.S. in Neurobiology, Physiology, and Behavior. I’m excited to be here to help out with neuropsychological testing and neuroimaging. When not in the lab, I enjoy traveling, hiking, exploring the city, and spending time with my friends and family.
I studied psychology and neuroscience at Reed College in Portland, Oregon. After graduating, I moved to Berkeley to work in neuroimaging before applying to grad school. My interests (other than neuroscience) include hiking and being outdoors, kickboxing, weightlifting, and music.
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.
