Ganna Blazhenets, PhD

Professional Researcher

M_Neurology

I am an early-career scientist with a background in physics and neuroimaging, completed my PhD at the University of Freiburg in Germany, focusing on multimodal neuroimaging techniques. In 2022, I began my journey as a visiting scholar at the Rabinovici lab, returning in 2024 as an assistant researcher.

Gillian Chen, MHA

Administrative Officer II

Neurology

I am an administrative assistant for Dr. Gil Rabinovici (and Dr. Howie Rosen). I help assist with the administrative needs for him and his lab. I also manage his scheduling, travel, and other miscellaneous tasks as needed.

Corrina Fonseca

Postdoc Scholar

Neurology

Dr. Corrina Fonseca completed her PhD in Neuroscience at UC Berkeley in 2026 in the Jagust Lab. Her doctoral research used multimodal neuroimaging, particularly amyloid and tau positron emission tomography (PET), to examine factors that drive spatial and temporal progression of Alzheimer's disease pathology.

Aidyn Rose Hills, BA

Asst Clinical Research Coord.

M_Neuro-Memory and Aging

Aidyn was born and raised in Portland, Oregon. In May 2024, she graduated from Whitman College with a bachelor’s degree in psychology and a minor in biology. She previously worked as a student researcher in the Psychology Department at Whitman College, investigating the effect of language framing on victim-blaming attitudes and prosocial behavior. Aidyn is now an Assistant Clinical Research Coordinator for the PET program in the Rabinovici Lab at the Memory and Aging Center.

Renaud La Joie, PhD

Assistant Professor in Residence

Neurology

Renaud La Joie, PhD, is the Edward and Pearl Fein Endowed Professor in Precision Care for Memory Disorders at UCSF. He is a neuroscientist and neuroimaging expert whose research focuses on understanding the mechanisms that drive Alzheimer’s disease and other neurodegenerative conditions. Using advanced brain imaging techniques, fluid biomarkers, and neuropsychological measures, Dr.

Orit Lesman Segev, MD

SPECIALIST

M_Neurology

I am a neuroradiologist–scientist with a special interest in biomarkers, and particularly imaging biomarkers in neurodegenerative diseases. 

Marlene Lin, MS

Neuroimaging Data Analyst

M_Neuro-Memory and Aging

Marlene is a neuroimaging data analyst in the Rabinovici Lab. Originally from Guangdong, China, she received her B.S. in Computational Biology from UCLA in 2023 and her M.S. in Health Data Science from UCSF in 2025. She joined the lab in late 2023 to pursue her capstone project on data-driven tau-PET subtypes in sporadic early-onset Alzheimer’s disease, and now supports various ongoing research projects related to Alzheimer’s disease.

Tedy Head Shot

Teodora Markova, PhD

Postdoc Scholar

M_Neurology

Teodora (Tedy) completed her PhD in neuroscience at Brandeis University, where she examined neuropsychiatric symptoms in healthy aging. Her work used multimodal neuroimaging methods to understand how individual differences in neuromodulator systems may moderate relationships between pathology and depressive symptom trajectories.

Witsarut Nanthasi

Student/Atlantic Fellow-GBHI

M_Neurology

Witsarut earned his medical degree and completed his neurology training at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand. He subsequently completed a fellowship in behavioral neurology and worked as a behavioral neurologist at Siriraj Hospital.

From 2025 to 2026, he was an Atlantic Fellow for Equity in Brain Health at the Global Brain Health Institute, UCSF. After completing the fellowship, he has joined the RabLab at UCSF as a visiting scholar to further develop his clinical and research skills in neurodegenerative diseases.
