I am a PhD student in the Department of Electrical and Computer Engineering at the University of Toronto, supervised by Prof. Shurui Zhou from FORCOLAB.

My main area of research is software engineering, with a focus on the sustainability of open-source and scientific software. My work involves applying mixed methods to explore sustainability challenges in scientific software from both social and technical perspectives, particularly within open-source ecosystems. I aim to design tools that can improve the collaboration among scientists while developing scientific software and help them write code more efficiently.
