My research

I am investigating ultrasound-based methods for rewarming frozen biological tissues, with the eventual application being ultrasound-based rewarming of cryogenically preserved organs.

I’m also interested in focusing ultrasound to the spinal cord, and working specifically to demonstrate the safety and feasibility of potential focused ultrasound spinal cord applications.


I began my studies in the Integrated Science program at McMaster University in Hamilton, Canada. In this program, I specialized in physics and biophysics, and wrote my undergraduate thesis on a simulation-based characterization of the elastic properties of different biological membranes.

I started my MSc in the Medical Biophysics department at the University of Toronto, researching methods for focusing ultrasound through the spine to the spinal cord. I reclassified to the PhD program in 2018 and defended my PhD in 2021.
