Hi!

I'm a Ph.D. candidate in Computer Science at Columbia University where I am part of the natural language processing group since Fall 2017. My research advisor is Smaranda Muresan.

Prior to joining Columbia, I worked as a Research Associate at the Center for Complex Engineering Systems (CCES) that is held jointly at King Abdulaziz City for Science and Technology (KACST) and MIT.

Research Interests

My research is in natural language understanding and machine learning. I work on on developing computational methods and resources for Argumentation Mining, Misinformation Detection and Fact-checking, and studying the overlap between these problems. I work on problems across the full fact-checking pipeline that include: check-worthiness detection, evidence retrieval, and claim verification. I am mainly interested in complimenting pre-trained language models with external knowledge relevant to these tasks (e.g. discourse information for argumentation mining, argumentation for check-worthiness detection, and common-sense knowledge models for detecting argumentative fallacies). I am also interested in analyzing the robustness of these models under adversarial attacks.
