Principal Investigator - NANo Lab
Assistant Professor of Biomedical Physiology and Kinesiology - Simon Fraser University
Canada Research Chair (II) in Neurophysiology of Aging and Neurodegeneration
Scientific Director - ImageTech Lab
Dr. Alex Wiesman is a cognitive neuroscientist who is passionate about finding new ways to understand and treat age-related brain disorders. Most of his research uses brain imaging to measure the functional, structural and molecular changes that lead to these disorders. In addition to his role as PI of the NANo Lab, he is also Scientific Director of SFU's human brain imaging Core Facility: ImageTech Lab. Alex completed his PhD in neuroscience at the University of Nebraska Medical Center with Tony Wilson and his postdoctoral training at the Montreal Neurological Institute with Sylvain Baillet. In his abundant free time, he likes to read fiction, throw pottery, cook overly-complicated meals, and travel to new places where he can eat lots of food.
Santiago Isaac Flores Alonso, PhD
Postdoctoral Fellow
Dr. Santiago Flores is a postdoctoral researcher at Simon Fraser University, where he applies artificial intelligence and neuroimaging to study brain aging. His research explores how brain function evolves over time, the factors influencing deviations in healthy aging, and the role of neurochemical systems in shaping brain connectivity. By leveraging advanced machine learning and high-performance computing, he develops innovative tools to analyze MEG/MRI data and uncover patterns that could improve early diagnosis and intervention strategies.
Bonnie Ng
PhD Student
Bonnie is a PhD student in the Department of Biomedical Physiology and Kinesiology at SFU, supervised by Dr. Wiesman. She is interested brain-behaviour relationships and the factors underlying individual differences in these associations. During her PhD, she will be involved in projects examining how health and lifestyle contribute to cognitive reserve, as well as projects investigating variability in brain signal across time, in both healthy and clinical population. Outside the lab, she plays the piano and enjoys taking really long walks.
Isabel Wilson
SSHRC MSc Scholar
Isabel is a master's student in the Department of Biomedical Physiology and Kinesiology at SFU, supervised by Dr. Wiesman. Her thesis will explore how brain activity varies across different timescales in healthy young adults. Her interests are broad, but include complex systems and the fundamental mechanisms of large-scale network activity. Outside the lab, she likes running and reading.
Sean Kriwokon
NSERC USRA Research Assistant
Sean is an undergraduate student from Airdrie, Alberta, studying in the Biomedical Physiology and Kinesiology department at SFU, with a major in Behavioural Neuroscience. He is working on a project that combines functional brain imaging with various biomarkers to learn more about the relationships between cellular energetics, inflammation, and neurophysiological alterations in Alzheimer’s Disease. He has a broad interest in the mechanisms underlying neurological disorders, and in the development of treatments to improve quality of life for patients. Outside of the lab, he enjoys reading and plays lacrosse with the Colorado Mammoth of the National Lacrosse League.
Polina Shahjahan
Undergraduate Research Assistant
Polina is an undergraduate student majoring in Biomedical Physiology within the Department of Biomedical Physiology and Kinesiology at SFU. In the lab, she assists in research investigating variability in brain activity over differing periods in healthy young adults. Her interests include neuroimaging and the mechanisms of neurodegenerative diseases. Polina is also particularly passionate about advancing women’s health through clinical research and improving healthcare outcomes. Outside the lab, she enjoys traveling, staying active, and exploring new films and TV shows.
Ako Sotiroff
Undergraduate Research Assistant
Ako is an undergraduate student pursuing a Bachelor of Science in Biomedical Physiology at Simon Fraser University. Her interests are many, some of which include neurodegenerative diseases, biophysics, and botany. She is co-leading the MRI 3D printing project at ImageTech, where we are developing a reproducible system for converting MRI scans into STL files to create 3D-printed brain models of research participants. Our ultimate goal is to enhance participant engagement in neuroscience research while establishing a user-friendly and accessible workflow. Beyond the lab, she has a passion for gardening, painting, and identifying native plant species in British Columbia.
Parham Fathi Naz
Undergraduate Research Assistant
Parham is a fourth-year undergraduate student majoring in Biomedical Physiology at Simon Fraser University. His interests lie in neurological disorders, neuroimaging, medical technology, and computational analysis. In the lab, he is co-leading the MRI-to-3D pipeline project, where we are developing a streamlined workflow to segment MRI scans, convert them into 3D-printable STL files, and produce physical brain models. This involves optimizing software tools, automating batch processing, and setting up a dedicated 3D printing system at ImageTech Lab. The goal is to create an efficient, reproducible process that enhances neuroanatomy visualization for research and education. In his free time, Parham likes to play soccer, watch movies, and spend time with friends.
Abdallah Abujamous
Postgraduate Research Assistant
Abdallah holds a Bachelor of Science in Biomedical Physiology from Simon Fraser University. He is currently working on a project focused on enhancing recruitment of research participants in clinical studies, aiming to bridge the gap between physicians and academic researchers to improve clinical practices. Additionally, Abdallah is involved in an emerging research project on Parkinson’s disease. His interests lie in healthcare, patient care, and working directly with patients in clinical settings. Outside of his professional pursuits, he enjoys traveling and exploring different countries and cultures.
Luis Muñoz
Postgraduate Research Assistant
Luis is a recent SFU graduate from the Behavioural Neuroscience program at Burnaby Campus. During his time as an undergraduate he specialized in human anatomy and circadian rhythms, and even got the opportunity to teach anatomy to other undergraduate students as a Teaching Assistant (where he obtained his passion for teaching). His current areas of interest focus on clinical neuroanatomy, sleep physiology and sleep medicine. His project will focus on processing a large Parkinson's disease neuroimaging database to improve accessibility for further research and analyses. Outside the lab, he has a passion for teaching, acoustic music and language learning.
