Hello, my name is Yinhua Piao, and I am a Ph.D. student in computer science at Seoul National University (SNU). I received my Bachelor’s degree in Computer Science from Jilin University in 2018 and my Master’s degree in Computer Science from the Bio & Health Informatics (BHI) lab at SNU in 2020. Currently, I am pursuing a Doctoral degree and working with Professor Sun Kim in the BHI Lab at SNU.
My research interests lie in developing computational methods to address complex problems in clinical and biomedical domains, such as personalized healthcare data analysis and drug discovery. Specifically, I focus on graph representation learning models and explainable, robust techniques, aiming to improve personalized medicine.
