Microsystems and nanosystems (MEMS/NEMS) are miniaturized engineering devices that are manufactured using micrometer and nanometer-scale structural components. We are now in the midst of an explosive growth in the development of micro/nanosystems for a staggering array of applications that includes information storage, sensors, displays, portable power generation, and medical diagnostics.
My research program develops rigorous, scale-dependent, processing-structure-property-performance-reliability correlations for micro and nanosystems. Ongoing activities include: (i) Analysis of energy dissipation and structural damping in micro- and nanomechanical resonators; (ii) Engineering the surface nanotopography of biomedical implants for optimized performance; (iii) Development of advanced materials for PowerMEMS (single-chamber solid-oxide micro fuel cells, micro engines, and piezoelectric vibration energy harvesters); and (iv) Design, synthesis, and characterization of nanocomposite materials for microactuators. These research activities are supported by grants from NSERC, FQRNT, Canada Research Chairs Program, Canada Foundation for Innovation, General Motors of Canada, and CIHR.
Multiple opportunities exist for undergraduate and graduate students to participate in collaborative research that utilizes a range of experimental, analytical, and computational techniques. Microfabrication and characterization are performed at the McGill NanoTools Micromachining Facility. Applications from talented and hard-working students are always welcome!
