Tri Vo

Hi I am Tri, currently attending Ryerson University pursuing a Bachelor in Computer Engineering. I was always fond of learning and discussing STEM. In my opinion, Math is not the most central, however it helps me understand the world thoroughly. I am also a big fan of music and other forms of art. I look forward to seeing you all and maybe talk about anything from philosophy, psychology to math and science or just simply say hi.
