Aside from math, music is a big part of my life, and I can be seen walking around Toronto vibing to Taylor Swift. I have been enjoying singing and playing the violin for many years and have been in all sorts of ensembles, including an acapella club.

Looking forward to competing at SLC again this year! I've participated in a variety of other competitions in my school career, including the Bow Seat Ocean Awareness Art Contest last year, and doing the Junior Breakthrough Contest three years in a row, submitting a high effort digitally hand drawn animation each time. Furthermore, I've participated in business and other STEM competitions, including attending the national FUSE business competition in eight grade. In my free time, I enjoy volunteering at a hospital and utilizing my marketing skills in general. :)
