Artificial Intelligence Researcher

LinkedIn Page       CV       Contact       Twitter

I currently serve as an assistant professor and Chair of the Health Informatics program at DePaul University in Chicago, IL, in the Department of Computing & Digital Media (CDM), as well as a professor of data science at Hanyang University in Seoul (Korea).  I was formerly a senior data scientist at several of the largest healthcare organizations in the world: Cigna, CVS Health, and Centerstone Research Institute (CRI). I received my PhD from the School of Informatics and Computing at Indiana University. Casey Bennett - TEDx Nashville

My work focuses on artificial intelligence & robotics in healthcare, including the areas of human-robot interaction, machine learning, data science, internet-of-things (IOT), digital health technologies, clinical decision support, and personalized medicine. I am currently working on research projects using robotic pets for therapeutic purposes with elderly patients, development of robotic sensor systems for tracking in-home patient health, and studying social cognition through human-robot interaction to create more life-like AI devices.  We get to do cool stuff like teach robots how to play video games and make furry cuddly robot pets, while also developing cutting-edge machine learning models (meta-learning, generative models, multi-modal transformers, etc.) that push the boundaries of AI in healthcare.

In my past, I have served as PI for studies on implementation of AI-driven clinical decision support technology in real-world settings for mental health, dementia, diabetes, and other chronic illnesses.  I have also led teams developing robotic sensor systems for improving everyday health beyond the clinic, as well as interactive robotic faces.  I've published dozens of scientific articles, done interviews for national and international magazines like ComputerWorld and Slate, and been a guest on nationally syndicated radio talk shows. My work has also been featured as a TED talk and as part of IBM's “Smarter Planet” campaign. 

*For prospective graduate students: I currently have 1-2 open positions in my research lab (한국 학생 위해서, 또한 저는 한국어로 말할 수 있습니다).  For outstanding applicants, research funding is available to help cover the cost of tuition. You will need to apply through DePaul University (Link here).  I am primarily in the Health Informatics program (Link), but also teach in the Data Science and Artificial Intelligence MS programs (program info) as well as Computer Science PhD program (PhD info)
