Professor Mohammad E. Khosroshahi received his B.Sc. (Lancaster University), M.Sc. (Swansea University), and Ph.D. in Applied Physics (Application of Lasers in Medicine) from Hull University (UK) in 1993 with a thesis on ophthalmological tissue ablation with tunable mid-IR and excimer lasers in collaboration with Moorfield’s Eye Hospital in London. He joined the Biomaterial and Tissue Engineering group of the Faculty of Biomedical Engineering at Amirkabir University of Technology (AUT) in Tehran where he became a Full Professor in 2010. He has been the Director of AUT Laser and Optics Research Center, Associate Dean of Research, and Chair of Biomaterial Group. In 2011, he chaired the conference session in ‘’Nanotechnology, Fundamentals & Applications’’ at University of Ottawa. In 2013, he joined the University of Toronto, Department of Mechanical & Industrial Engineering (MIE) as a Visiting Professor working on ‘’Contrast-enhanced photoacoustic imaging of Tumor’’ at the Center for Advanced Diffusion-Wave and Photoacoustic Technologies (CADIPT). He then continued as a research associate at CADIPT working on the contrast-enhanced imaging of blood. In 2015, he chaired the ‘’Biosensor and Nanotechnology’’ at World Congress on Medical & Biomedical Engineering, Toronto, and became an adjunct Professor at MIE in 2018. Currently, Professor Khosroshahi is Director of the Nanobiophotonics and Biomedical Research Lab at MIS-Electronics Inc. in Richmond Hill where he is working on the development of novel colloidal and substrate nanobiosensors for targeted detection of breast cancer biomarkers such as HER-II and CA 15-3 in blood serum. He is a member of the Advisory Board of the Institute for Advanced Non-Destructive & Diagnostic Technologies (IANDIT) at the University of Toronto, a Fellow member of the Institute of Nanotechnology, a member of the Editorial Board of the Journal of Nanomedicine and Nanotechnology, the Canadian Association of Physics, Canadian Medical and Biological Engineering Society, Optical Society of America, and SPIE.
