Dr. Dahman has research focus on several emerging areas of technology in the fields of Biotechnology, Nanotechnology, with special interest in Biomedical Engineering. He has commissioned a state-of-the-art research facility at Ryerson to conduct his research projects, which were funded by several agencies including Ryerson University, NSERC and Ministry of Agriculture Canada.

Dr. Dahman has long experience in developing medical devices for the health care industry, such as developing and testing novel wound dressing materials for chronic wounds. ?His is currently working on designing and synthesizing novel nano-structured biomaterials with focus on improving health care industry.

His research activities were evolved into the production of biofuels from renewable resources such as agricultural crops and wastes. He is also actively involved in developing and testing new types of bioreactors that are mainly utilized in fermentations and other biotechnology applications.

In the past five years, Dr. Dahman has supervised nearly 20 graduate student theses projects, and published several peer-reviewed articles, book chapters, and conference proceedings. His research team has participated in several national and international conferences in addition to local and regional meetings.
