Research
Dr. Bae's research is pioneering the advancement of predicting risky health behaviors through cutting-edge applications of ubiquitous computing and machine learning. Her expertise lies in health monitoring and support systems, with a particular emphasis on vulnerable populations. Her overarching research objective is to establish a foundation for a personalized intervention system that empowers at-risk populations. She achieves this by harnessing the potential of mobile sensing and human-centered AI design strategies, all contributing to positive behavior change in health and safety. She has successfully developed a mobile AI system capable of predicting 30-day hospital readmissions for post-surgical cancer patients. This system's capabilities have been extended to encompass estimating symptom severity during chemotherapy, predicting high-risk alcohol consumption, and predicting marijuana intoxication in young adults. Dr. Bae's groundbreaking work has earned her recognition, including the Best Paper Award in Cancer Informatics, published in ACM, and featured in Forbes News.
