Hongjie Chen

I earned my Ph.D. in Computer Science from Virginia Tech, where I was supervised by Dr. Hoda Eldardiry. My research centers on deep graph learning and deep time-series learning, extending into the area of recommendation systems and data analytics. I aim to bridge the gap between graphs and time series for tasks like link prediction and time-series forecasting. I've had the privilege of collaborating with researchers from Adobe Research and Yahoo Research in related fields.
