Hi! This is Ruixuan(Sophia), a 4th-year Computer Science Ph.D. student working with Dr. Joseph Konstan at University of Minnesota. I earned my Bachalor’s Degree of Computer Science from Georgia Institute of Technology in 2019. After graduation, I’ve worked as a Software Engineer at Yelp for two years before starting my Ph.D. journey at UMN.

My research interests include: Human-centered AI, Social Computing, Recommender Systems, and Applied Machine Learning. In particular, I’m passionate about user interest modeling, behavior understanding, beyond-accuracy evaluation and optimization. I have expertise in mixed-method study design and extensive experience in running large-scale online field experiments powered by A/B tests. In general, I love training models and conducting user evaluation to understand how we can better serve human beings with AI-powered technology!

Please see my CV for more detailed experience.
