Sebastian Wachsmann Hogiu

Sebastian Wachsmann Hogiu is a Professor in the Department of Bioengineering at McGill University's Faculty of Engineering, based in the Macdonald Engineering Building in Montreal, Quebec. His research program bridges engineering, materials science, and medical diagnostics to address global health challenges through innovative technological solutions.

Dr. Hogiu's research focuses on developing novel nanobiomaterials with applications in global health and development. His primary research areas include nanomanufacturing of nanocomposite materials, characterization of these materials, and applications in biosensing, antimicrobial technologies, water purification, and clean energy. A significant portion of his work centers on biosensing with Raman and Plasmonics, particularly Surface Enhanced Raman Spectroscopy (SERS), where he develops novel platforms for the detection and characterization of molecules and sub-micrometer organelles like exosomes.

Analysis of his recent publications (2024-2025) reveals a strong emphasis on point-of-care diagnostic technologies, with particular focus on miniaturized and portable biosensors, nanomanufacturing of functional biomaterials, and advanced optical detection methods. His work demonstrates a clear trajectory toward developing inexpensive, field-deployable diagnostic tools that can operate in resource-limited settings while maintaining high sensitivity and specificity.

Dr. Hogiu leads a research laboratory with the mission to develop and apply technologies for global health and development problems. The vision of his lab is to address problems of global relevance by challenging paradigms and shattering disciplinary barriers, reflecting an interdisciplinary approach that combines elements of engineering, materials science, and biomedical research.
