Parsin Haji Reza

Professor Parsin Haji Reza joined the University of Waterloo in April 2018 as an Assistant Professor in Biomedical Engineering within the Department of Systems Design Engineering, after completing his doctoral (2015) and postdoctoral research (2018) at the University of Alberta and completing an undergraduate degree in optical engineering at MMU Malaysia (2010).

So far, Dr. Haji-Reza secured more than $2 million in research funding as the principal investigator to support his interdisciplinary research program. Dr. Haji-Reza has authored more than 25 high impact peer-reviewed journal papers such as Nature's light: science and application (2017, Impact factor 15.1) and Optical ( July 2018, Impact factor 9.2). He also holds more than 6 patents to date.

Dr. Haji Reza is interested in designing and developing novel hardware and software methods for clinical and pre-clinical biomedical applications. These new technologies aim to provide clinicians and researchers with novel capabilities and information that is presently difficult to obtain with existing techniques. He pioneered several new technologies/concepts including, Photoacoustic Remote Sensing (PARS) microscopy, a novel absorption-based, non-contact, non-invasive, label-free imaging technique.

In November 2014, he co-founded a start-up company illumiSonics inc., holding the position of CEO from November 2014 to March 2018. illumiSonics is currently focused on commercializing PARS technology for pre-clinical and pharmaceutical applications. During Dr. Haji Reza's leadership role at illumiSonics, he raised private investments and attracted notable individuals and international companies. He is currently the Chairman of the Board and the chief technology officer of illumiSonics, overseeing the major policies and decisions of this Company.

Dr. Haji Reza and his team continually strive to maintain an extremely dynamic, respectful, intellectual, fun, and creative environment. The team is working on cutting-edge research in biomedical engineering and biophotonics, including non-invasive non-contact optical imaging methods, micro-endoscopy designs, handheld, and portable medical imaging techniques, design, and fabrication of nano-structured sensors, image processing, Machine Learning methods, Capacitive micromachined ultrasonic transducers, and novel deep optical imaging tomography methods. The team pursues applications in Ophthalmology, Oncology, Dermatology, Neurology, Cardiology, Dentistry, Pharmaceutical, and Pre-clinical research.

The research philosophy of PhotoMedicine labs is transitional research from bench to the bedside. We are always looking to collaborate with talented students, faculties, researchers, clinicians, and industry.
