I am a programmer & aspiring GIScientist

About Me

I am a passionate creator who loves programming, GIS, and problem-solving. I am currently pursuing the intersection of my interests as a Ph.D. student in the Spatial Analysis and Modeling Lab at Simon Fraser University. My research focusses on advancing geospatial artificial intelligence methods. I am also an avid reader and a dedicated soccer player.
