Mechanical Engineering Research

The Bioengineering research groups and laboratories conduct studies on various applications and models in the field of Cardiovascular Engineering, Voice Production, Bone fracture and osteoporosis, Mechanics of Biological Materials, and Biomimetics. Current research projects include the following: designs of new vascular stents and catheters,  structural and multi-objective optimization of stent-like cages for rotating catheter protection, characterizations of biological tissue, models of voice production, design constructions and evaluations of implants for vocal fold alteration and reconstruction, numerical simulations of laryngeal flows (CFD), damage accumulation patterns in healthy and diseased bone, fractures of tooth enamel and dentin, and the development of novel ìbio-inspiredî composites.

Our primary facility is the Cardiovascular Engineering Laboratory (the McGill and Montreal Heart Institute).  It houses a PIV system from TSI, a Rheometer from Bohlin, a Pulsatile pump from Harvard Apparatus, a Bio-pump from Medtronic, Roller pumps from Masterflex, ELF3200 Mechanical tester for soft tissues from Enduratec, High precision pressure gages, EMF flow meters and various modeling software (Fidap, Matlab, Labview, Ansys, Pro-E, ICEM, Femlab). As for facilities involved with voice production, they contain the following: a Dantec time-resolved PIV system, a Dantec hot-wire anemometry system, one Dantec LDA, one Varian gas chromatograph, one Agilent Vxi data acquisition system, one Polytec LDV system with both standard and fiber optic heads, one B&K sound level meter, microphones, accelerometers, pressure and flow transducers, computers, and software (Abaqus, Fluent, Comsol, Power Flow, Solid Works). Not only do our research groups measure the mechanical properties of small bone or teeth sample with miniature loading stages, but they also monitor any small-scale deformation and fracture mechanisms with optical or atomic force microscopy.

Other than this laboratory, our groups have access to CLUMEQ supercomputing facilities to model and hypothesize the deformation and fracture processes in biological tissues.

Research funding is primarily contributed by the federal, and the provincial government through CIHR, NSERC, CFI, FRSQ, FQRNT. Funding from the NIH NIDCD grant (R01 DC005788) and industries such as Medtronic, Baylis Medical, Coroneo Medical, Opsens Inc, are significant contributers as well.
