Dr. Villeneuve did a first postdoctoral fellowship under the supervision of Professor William Jagust at the Helen Wills Neuroscience Institute, University of California Berkeley. A central focus of her research was to examine the interplay between beta-amyloid deposition, vascular diseases, and cognition in the preclinical phase of Alzheimer’s disease. Dr. Villeneuve did a second postdoctoral fellowship at Northwestern University under the supervision of Professor Todd Parrish and in collaboration with the Cognitive Neurology and Alzheimer’s Disease Center. This second training involved the proposing of a multimodal MR-based imaging battery to determine the predictive value of neurovascular insults, such as deterioration of the blood-brain barrier or reduced cerebral vascular reactivity, to detect early changes associated with amyloid pathology. Dr. Villeneuve received her PhD at the Université de Montréal under the supervision of Professor Sylvie Belleville and has been a member of the Ordre des Psychologues du Québec since 2009.
Dr. Villeneuve’s work is currently supported by the Canadian Institutes of Health Research.

Postdoctoral Researchers
Sofía Fernandez-Lozano
Sofía is a postdoctoral fellow in the Villeneuve Lab. She trained in clinical psychology at the Universidad Autónoma de Baja California and in neurobiology at the Universidad Nacional Autónoma de México (UNAM), where she used functional MRI to study addiction. She then obtained her PhD in Neuroscience from McGill’s Integrated Program in Neuroscience under the supervision of Dr. Louis Collins, developing structural MRI biomarkers to predict progression to Alzheimer’s disease. In the Villeneuve Lab, she uses structural equation modeling to study how cardiovascular risk relates to Alzheimer’s pathology, neurodegeneration, and cognition before symptoms appear. Outside the lab, Sofía collects old film cameras and practices her French by reading women and queer writers.

Ting Qiu
Ting completed her PhD in the Integrated Program in Neuroscience at McGill in 2026, using PET and MRI to study how amyloid and tau affect brain structure and cognitive resilience. She now integrates neuroimaging, fluid biomarkers, and clinical data to understand why people with similar Alzheimer’s pathology decline differently, and how lifestyle can inform prevention. Outside the lab, she enjoys badminton and exploring new places.

Doctoral Students
Yishu Chao
Yishu received her BAs in Cognitive Science and Computer Science from the University of California, Berkeley. Under Dr. Lea Grinberg’s supervision, her undergraduate honors thesis examined the correlation between PET and histological tau signals. After graduating, she worked as a staff research associate in Dr. William Jagust’s lab, investigating the role of risk factors in aging and Alzheimer’s disease using multi-modal human neuroimaging methods. In 2026, she began her PhD in the Integrated Program in Neuroscience at McGill and will continue studying Alzheimer’s disease using fluid and PET biomarkers, with an interest in clinical trials and early prevention strategies. In her free time, Yishu loves reading and is learning ballet and pottery.

Alfonso Fajardo-Valdez
Alfonso earned a bachelor’s degree in psychology and an MSc degree in neuroscience at the National University of Mexico (UNAM). During his bachelor’s, he investigated the influence of early life stress on the later onset of impulsivity. During his master’s, he examined the correlation between resting-state fMRI functional connectivity and cognitive impairment in temporal lobe epilepsy. Alfonso is interested in cognitive neuroscience, neuroimaging analysis, and cross-species comparative studies. During his PhD, he will assess amyloid-beta and tau pathology progression in individuals at risk of Alzheimer’s disease. Alfonso is a lover of coffee and a huge fan of Star Wars, Harry Potter, and the Lord of the Rings sagas. During his free time, he enjoys playing chess, hanging out with friends, and reading novels and scientific diffusion books. He also loves programming and coding stuff.

Lylou Guilloton
Lylou completed her BA in Psychology with a minor in Linguistics, and MSc in Health Sciences from Concordia University. During this time, her field of interest was sleep and cognitive health in older adults. She joined the Integrated Program in Neuroscience at McGill for her PhD in 2026, and will begin her work investigating how sleep-wake regulation, particularly orexin signaling and sleep physiology, influences the development and progression of Alzheimer’s disease. In her free time, Lylou can be found sitting with her cats while knitting, watching a movie, or reading.
Amelie Metz, FRQS Fellow
Amelie completed her BA in Speech and Language Therapy at LMU Munich, Germany, an MSc in Psychological, Neurological, and Clinical Linguistics at University of Salzburg, Austria, and an MSc in Neuroscience with focus on neural stem cells and nervous system repair at King’s College London, UK. She joined McGill in 2022 as a rotation PhD student. Since September 2023, she is co-supervised by Dr. Villeneuve and Dr. Mahsa Dadar, investigating the relationship between neurodegenerative and cerebrovascular pathologies, specifically white matter hyperintensities, and clinical symptoms in dementia patients. Outside the lab, Amelie enjoys yoga, reading, and attending concerts of the OSM.
