Dr. Chen Dan 丹晨

I am a postdoctoral researcher at TTIC working with Prof. Avrim Blum. In 2022, I graduated with Ph.D. degree from Computer Science Department, Carnegie Mellon University, advised by Pradeep Ravikumar. Prior to this, I received B.Sc from School of EECS, Peking University, where I worked with Liwei Wang.

I am looking for research positions in the industry.

CV (last updated: Apr 2023)

My research interest is in the broad area of robust statistical learning, with an emphasis on the theoretical understanding and practical algorithms for learning under various types of adversarial distribution shift. This encompasses many new challenges in ML, including:

• Adversarial Examples: See e.g. my papers in ICML'20a and ICLR'20;
• Class/Group Imbalance: ICML'21 and ICML'20b;
• Outliers in Data: ICML'21.
