I began my PhD at McMaster University in 2010. 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 am contributing to the development of lifetime spectroscopy, an emerging defect characterization technique pioneered by Stefan Rein at the Fraunhofer ISE [S Rein, Lifetime Spectroscopy, Springer (2005)].

We will need this technique in the future, when the density of efficiency-limiting defects in semiconductor devices is reduced below the detection limit of deep-level transient spectroscopy (DLTS, the current standard for characterization of defects in semiconductors).

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).
