Economic depression has life-changing effects on the entire population, and may happen without warning. This report outlines the prediction and analysis of stimulated macroeconomic data provided by Scotiabank during their Risk Analysis competition held at UBC in February, 2019. We attempted to forecast the next depression based on the trends of 20 variables. This report was a collaborate effort of the four authors, and received first place in the competition. 

The honey bee is a major part of our ecosystem, and its declining population is a threat to global agriculture. This short research paper explores the results of various field experiments studying the effect of neonicotinoids on bees and colony collapse disorder. This paper was nominated for the First Year English Award at the University of British Columbia in 2015. 

This literary paper analyzes Dionne Brand's What We All Long For through an objective lens. As a Chinese-born Canadian, I am particularly fascinated by Canadian literature, particularly of the Asian Diaspora.
