Tell us a little about yourself, including what inspires you to learn and continue in your chosen field

I’m a master’s student in Chemistry, working in the SFU Nuclear Science Laboratory. I played a key role in assembling the 8pi gamma-ray spectrometer, a complex high-energy light radiation detection system. I’m using the spectrometer as a tool for medical imaging research. In particular, I’m researching new approaches to Positron Emission Tomography (PET) scans that could possibly provide better imaging qualities and patient outcomes. What inspires me to continue is my passion for learning and the satisfaction of overcoming difficult challenges. I also find medical imaging research especially rewarding because of its direct impact on healthcare.

Why did you choose to come to SFU?

I chose to come to SFU after high school because of its proximity to home and also the programs offered. I decided to stay for a graduate degree because it gave me a chance to apply what I have learned in undergraduate studies. The hands-on experience is invaluable and exceeds what can be gained through classes alone. SFU has also provided me with a diverse skillset that aligns with current practices in my field.

How would you describe your research or your program to a family member?

Cancer is the leading cause of death worldwide and kills 1 in 4 Canadians. One powerful tool that is used to the fight cancer is medical imaging. It allows doctors to non-invasively locate cancer in the patient which guides decisions for treatment. PET scans are a type of medical imaging technique that measures gamma-ray radiation. I am assembling a complex gamma-ray radiation detector that I can use as a tool to research a new approach to PET scans. This new approach could possibly improve imaging quality and patient outcomes.

What three (3) keywords would you use to describe your research?

Gamma-Ray Spectroscopy, Positron Emission Tomography, Nuclear Science

How have your courses, RA-ships, TA-ships, or non-academic school experiences contributed to your academic and/or professional development?

Experiences such as poster and oral presentations have helped me develop an intimate understanding of my project, allowing me to effectively communicate my research to a broader audience. This is just as important as the research itself—after all, research holds little value if you can’t share it with others. For example, the Three Minute Thesis Competition requires me to condense years of research into a three-minute talk for a general audience. This is not only useful for pitching my research, but also for developing effective communication soft skills essential for professional development.
