Jaemin Yoo

Postdoctoral Researcher at Carnegie Mellon University

I am a postdoctoral research fellow at Carnegie Mellon University, working with Prof. Leman Akoglu. I received my Ph.D. and B.S. in Computer Science and Engineering from Seoul National University, where I was advised by Prof. U Kang. I am a recipient of the Google PhD Fellowship and the Qualcomm Innovation Fellowship. My research interests include graph mining, graph neural networks, time series forecasting, and interpretable tree models.
