College education offered Hanyu a lot of opportunities to deepen her understanding about data science. As a research assistant in biostatistics lab, Hanyu was impressed by the effectiveness of using data science tools to predict genetic disease risks based on genotype data. Later, her joined the High Throughout Computing Center (CHTC) of UW-Madison as a part-time data analyst and helped CHTC improved user experience by integrating and analyzing various user information. During Hanyu’s last semester at Madison, she also worked with Prof. Tyler to help ease traffic pressures in Madison by designing a flexible traffic light patterns using optimization techniques.
