ViTAL Lab Computational Behavior and Health Analytics

Currently, we are actively recruiting 1 - 2 Ph.D. students from Emory CS and GT ML programs. Please contact Dr. Kwon or apply for those programs, if you are interested in Computer Vision, Ubiquitous Computing, and Machine Learning techniques for Health Analytics.

Computational BehaVior and HealTh AnaLytics (ViTAL) Lab strives to develop artificial intelligence (AI) systems that are inclusive, accessible, fair, and reliable that will effectively improve the healthcare system. Our mission is to develop Ubiquitous Computing, Computer Vision, and Machine Learning systems using distributed ambient, mobile, and wearable devices to monitor patients’ conditions in hospitals or everyday life. We are also invested in deploying and testing the developed AI systems in real-world clinical and daily living environments actively collaborating with stakeholders in healthcare.
