I finished my PhD at McMaster University in 2016. My research involves experiments that can be used to identify which defect is limiting the efficiency of a solar cell.

My hobbies include music, electronics, skateboarding, and art. I currently play in the band stereography and have produced recordings of songs that I have written with friends over the years.


I grew up classically trained in violin (Suzuki) and piano (Conservatory), and later picked up saxophone, guitars, drums, and others. When I was 15, I quit music for a few years. I got back into music when I began jamming, writing, and recording in 2005. I currently play near Hamilton with stereography and have recordings on SoundCloud

Current Research

For my PhD, I have built a temperature-dependent time-resolved photoluminescence experiment, and developed new models that I have used to analyze the data and obtain the radiative-efficiency and characteristics of the dominant defect.

High radiative efficiency is necessary to reach thermodynamic efficiency limits for solar energy, and solid-state lighting.

Photoluminescence Decay

The carrier-lifetime can often be measured by observing the decay of light emission (PLD) from a meterial following fast excitation (e.g. from a pulsed laser).
