Dr. Mohammadi is a mechanical (biomedical) engineer with hands-on experience in the design of many engineering structures and medical devices through various projects that he has been involved in over the past few years. He is an industry innovator having created the technology to produce lifelike synthetic platforms that can be used for the simulation of almost all cardiovascular reconstructive surgeries. Among his other scientific activities, analysis and optimization of engineering structures (pipelines, containers, tanks, pressure vessels), artificial lift technology (mechanical problems in oil recovery industry), vibration in mechanical systems and dynamic analysis (collapse load), optimization of frames, shell, and inflatable structures (rigs, cranes, elevators), and fatigue and fracture analysis, are noticeable.  He worked for a few years as a consultant, research engineer and team leader for a variety of companies. In his last industrial position prior to joining UBC, he served as a technical advisor at Trican Well Service LTD working on unconventional sources of energy. He’s been heavily involved in the design and development of cardiovascular devices and technology for the past 10 years. He is a member of the association of professional engineers in the provinces of Alberta and BC.

His motto for life is easy: 

Learn mathematics and coding for no reason, be honest, stay with your problems longer, be intuitive, and always learn the rules and play better.

Research Interests & Projects

The active projects at the Heart Valve Performance Laboratory (HVPL) are as follows:

The Next Generation of Prosthetic Heart Valves

  • Percutaneous heart valves for the aortic and mitral positions
  • Application of soft robotic to the construction of prosthetic polymer heart valves for the aortic position
  • Bileaflet mechanical heart valves

Atherosclerosis: assessment of atherosclerotic plaque composition during progression in vivo using optical techniques

Orthotics: The next generation of shoe insoles using cryogel biomaterials

Parkinson’s disease: Design and development of a novel passive hand tremor attenuator

Researchers from UBC’s Okanagan campus have developed a new advanced mechanical heart valve that could have a major impact on the way cardiovascular surgeries are performed.

“This new valve design addresses some of the shortcomings of the existing solutions by providing more (blood) circulation through the heart by virtue of its innovative design,” said Hadi Mohammadi, a biomedical engineering professor at UBCO.

He said there had been few innovative approaches taken for many years and believes the synthetic heart valve could be a game changer for both surgeons and patients alike.

Guy Fradet, head of cardiovascular surgery at Kelowna General Hospital and a partner on the research, said the new valve has the potential to replace two existing valve designs that have been used since 1977 and 1994.

The two researchers concede that significant additional development and testing are required before the valve is made available to doctors, but they are excited about the next steps.

“If our designs and hypothesis hold up to further testing, this new valve design could replace all existing heart valves, both mechanical and bioprosthetic,” said Mohammadi. “It could revolutionize cardiovascular surgery.”
