Ryuhaerang Choi

Digital Health Researcher

About Me

I am Ryuhaerang Choi, a Ph.D. student in Networking & Mobile Systems Lab at KAIST, advised by Prof. Sung-Ju Lee. From July 2023, I have been working as a research intern at Nokia Bell Labs, mentored by Dr. Soumyajit Chatterjee, Dr. Dimitris Spathis, and Dr. Mohammad Malekzadeh.

My research centers around understanding individuals’ behaviors reflecting cognitive processes and mental health. I develop intervention systems to address mental health challenges based on this understanding. I aim to promote mental well-being and facilitate positive behavior changes through practical interventions, making a meaningful contribution towards building a healthier society.
Research Interests: Digital Health, Human-Centered ML, Interaction Design
