Human-centric
Data Science Lab

We strive to understand the human world through data analysis using various computational and algorithmic tools, such as Machine Learning and Deep Learning. Our current research interests lie in biosignal data (ECG, EEG, PPG signals, etc.), mobility data (human mobility data, driver safety sensing data and intelligent mobility data including in-vehicle cyber security), and various other data (water leakage, wafer defect pattern data and sound data to name a few).

We are always looking for new members to join us on our journey to understanding the world, one dataset at a time.

If interested, please contact us!
