Sunmoo Yoon, PhD

  • Associate Research Scientist
Profile Headshot


Sunmoo Yoon's research has focused on self-management, informatics, and artificial intelligence/machine learning (AI/ML) to reduce health disparities for the past 14 years. Yoon has 10 years of formal training in informatics at Columbia University. Yoon pioneered developing an analytic framework for Twitter in 2010 when Twitter was four-years old in her doctorate dissertation. Yoon's team has developed an informatics competency measurement called the Self-Assessment of Informatics Competency Scale (SANICS) tool for all health professionals, and it has been translated into different languages. Dr. Yoon is a Principal Investigator of a Twitter-based intervention trial project for Hispanic/Latinx and African American dementia caregivers (NIH Stage II-III TweetS2 trial, R01 AG060929). Yoon's TweetS2 team applying AI/ML techniques received the best paper award from International Medical Informatics Association in 2020, 2021 and 2022. Yoon's work analyzing Ebola Tweets has been recognized as a groundbreaking finding by other disciplines, including business and pharmacology, with 40 international media outlets, including CNBC, Slate, and Economic Times.
