Siyi (Reyna) Wu

I am a fourth-year Ph.D. candidate in the Department of Computer Science at the University of Toronto, supervised by Professor Steve Easterbrook.

My research sits at the intersection of climate informatics, human–computer interaction, and explainable AI. My dissertation adopts a mixed-methods approach that integrates quantitative climate and ML analyses with qualitative studies of climate scientists’ lived experiences. This work examines how machine learning functions as a sociotechnical system within scientific workflows, epistemic cultures, and institutional infrastructures, and identifies gaps between prevailing ML framings and scientists’ situated needs.

I obtained my Bachelor’s degrees in Computer Science and Mathematical Statistics with honors from Wake Forest University. I then earned my MSc in financial technology at Hong Kong University of Science and Technology.
