• Constructed a free-space mid-IR spectrometer to perform trace gas analysis of volatile organic compounds (VOCs) in human breath samples for the early detection of lung and breast cancer using cavity ringdown.
• Demonstrated the ability to detect parts-per-trillion (ppt) concentrations of VOCs emitted from a calibrated reference source
• Contributed to design calculations by determining minimum specifications for the bandwidth of HgCdTe mid-IR photodetectors to minimize noise without introducing signal distortion
• Designed a database to store spectrometer measurement data using MySQL, and integrated the automated pushing of measurement results to the database into the LabVIEW control software
• Lead the effort to identify the root cause of offgassing from manufactured breath sampling devices as the piston seal, and identified a replacement which provides a better seal, results in quieter operation, and.
• Developed a methodology in Python to remove background environmental signals from breath measurements involving a linear regression approach to fit measurement data

Hamilton, ON

• Developed fluorescent rare earth and transition metal-based nanomaterials for use with InGaN microLEDs to enhance the colour quality of white light sources for display applications
• Improved nanoparticle fluorescence efficiency by 41% through the introduction of a doped/intrinsic core/shell architecture, and demonstrated the ability to tune the peak absorption wavelength by 40 nm through the.
• Leveraged defects present at nanoparticle surfaces to accommodate luminescent dopant ion concentrations 10x higher than bulk materials without observing concentration quenching
• Designed comprehensive electro-optical systems, including a single photon counter capable of measuring sub-100 ns fluorescence lifetimes to demonstrate non-radiative energy transfer processes between co-dopant ions.
• Demonstrated the ability to remove and replace stabilizing surface organic ligands to alter the polarity of the nanoparticle surface to extend their compatibility with various dispersing solvents
• Familiar with wet chemical colloidal synthesis, etching, and film deposition in clean room environments
