Karen Cullen

Dr. Karen Cullen is a Senior Lecturer in the Department of Anatomy & Histology, within the School of Medical Sciences at The University of Sydney. Her research focuses on neurodegenerative diseases, particularly Alzheimer’s disease, inflammation, and cardiovascular-related neurological conditions. She investigates microvascular pathology, protein aggregation, and neurotoxic mechanisms in aging and disease. Dr. Cullen has contributed to over 20 peer-reviewed publications since 2005, exploring topics such as neuritic plaques, kynurenine pathways, and photobiomodulation effects in non-human primates.

Her work spans experimental models (e.g., triple transgenic mice) and human brain tissue analysis. Key themes include understanding the interplay between microvascular dysfunction, neuroinflammation, and neurodegenerative processes. Dr. Cullen has secured grants from organizations like the Rebecca L Cooper Medical Research Foundation and the Judith Jane Mason Foundation, supporting studies on Alzheimer’s pathology and neuronal energy crises.

Recent publications highlight advancements in Alzheimer’s plaque characterization, tau pathology, and actin-microtubule dynamics. Her research bridges basic science and clinical implications, aiming to uncover therapeutic targets for neurodegenerative diseases.
