About

I am a second-year doctoral student advised by Dr. Shalmali Joshi and Dr. Pierre Elias at the Department of Biomedical Informatics at Columbia University.

Previously, I was a researcher at the National Cancer Center-Korea and received my Master of Science in Information Systems at Cornell Tech and Bachelor of Arts in Mathematics at New York University.

My first name is Young Sang but I go by Young (like the opposite of “old”). You can reach me via email at young{dot}sang{dot}choi{at}columbia.edu.

Research

My research is on machine learning for clinical informatics with a focus on multimodal learning.

In particular, I am currently exploring the following:

• When does the inclusion of more input modalities improve the performance and robustness of predictive models?
• Does domain knowledge on the relationship between modalities and learning tasks help us better model multimodal interactions?
• Can shared and synergistic information from multiple accessible modalities replace more inaccessible modalities in clinical decision support?
