About

I am a PhD Candicate in the Computer Science Department at Carnegie Mellon University, where I am advised by Prof. Christos Faloutsos. During my PhD studies, I’ve also spent time at Adobe Research (2021), Microsoft Research (2020), and Amazon (2019, 2018) as a research intern. My PhD studies are supported by the Bloomberg Data Science PhD Fellowship and the ILJU Foundation PhD Fellowship.

Research Interests

Graph Machine Learning, Dynamic Networks, Knowledge Graphs, Anomaly Detection, Explainable AI.
