The lab proudly congratulates Dr. Fahad Almuqhim on the successful defense of his PhD dissertation titled:“Self-Supervised Representation Learning from Multi-Cohort Neuroimaging for Neurodevelopmental and Neurodegenerative Disorders.”.
Dr. Almuqhim’s research addresses a critical “identity crisis” in neuroimaging AI: Are our models actually identifying disease, or are they simply picking up on the technical quirks of a specific MRI scanner?
Under the guidance of Prof. Fahad Saeed at Florida International University, Almuqhim developed NeuroCLR. This novel, region-wise self-supervised contrastive learning framework is designed to filter out “site noise” and focus on what matters most: authentic neural signatures.
Key Breakthroughs in this dissertation:
-
True Generalization: By training on massive multisite datasets like ABIDE and ADNI, NeuroCLR creates representations that remain accurate across different hospitals and cohorts.
-
Neural Invariants: The research proves that self-learning models can identify universal brain patterns shared across different neurological disorders.
-
Robust Biomarkers: These site-invariant models significantly improve the performance of downstream tasks, such as clinical diagnosis and classification.
His Dissertation Committee consisted of Dr. Angela Laird, Dr. Leonardo Bobadilla, Dr. Ananda Mondal, and Dr. Kaoutar Ben Ahmed.
Dr. Almuqhim also wanted to recognize the support and collaboration of his fellow lab members, whose contributions and discussions played an important role throughout this work.
We congratulate Dr. Almuqhim on this major milestone and look forward to his continued impact in AI-driven neuro-imaging research. He joined Imam Mohammad Ibn Saud Islamic University in Saudi Arabia, as Assistant Professor. Congratulations again!
