Daniel Schonhaut, PhD

Research Scientist
Neurology

I completed my PhD in neuroscience at the University of Pennsylvania in 2022, with work decoding time and space from single-neuron activity in hospital patients undergoing intracranial electrode implantation. As a research scientist at the Memory and Aging Center, I help coordinate activities in the PET imaging core and conduct independent research on PET biomarkers of Alzheimer's disease, with a focus on early-onset and atypical clinical variants alongside longitudinal modeling of disease progression.

David Soleimani-Meigooni, MD

Assistant Professor
Neurology

Dr. David N. Soleimani-Meigooni is a neurologist who cares for patients experiencing cognitive symptoms as a result of neurodegenerative diseases such as Alzheimer's disease.

In research, Soleimani-Meigooni focuses on advancing precision-medicine approaches to diagnosing Alzheimer's disease and other neurodegenerative diseases. He looks at using positron emission tomography (PET) to image amyloid-beta and tau (protein fragments that accumulate in the brains of people with the condition).

Fleur van der Linden, BS

Visiting Graduate

Fleur is a master’s student from the Netherlands. In 2022, she obtained her bachelor’s degree in biomedical sciences at Maastricht University and started the Neurosciences Master’s program at the VU in Amsterdam. In 2023, she was an intern in the team of Dr. Ossenkoppele at the Alzheimer’s Center in Amsterdam. Here she investigated the Cavum Septum Pellucidum in a population at risk for Chronic Traumatic Encephalopathy using MRI metrics.

Agathe Vrillon

Student/Atlantic Fellow-GBHI

I am a cognitive neurologist and currently an Atlantic fellow for Equity in Brain Health, at the Global Brain Health Institute, UCSF. 

I completed my neurology residency at Paris Cité Université, France and served as an attending at the Cognitive Neurology Center, led by Pr. Claire Paquet, at Lariboisière University Hospital, Paris. 

Charles Windon, MD

Assistant Professor
Neurology

As a clinical fellow, I participate in the evaluation and management of patients in both clinic and research. My research interests center on aging and dementia within different ethnic groups and the differences in biomarkers among particular ethnic groups.
