About Me

I'm a second-year PhD student advised by Prof. John Paparrizos at The Ohio State University.
I'm currently working on Time-Series Anomaly Detection. Specifically, my research interests are centered around three main pillars:

Automation - building end-to-end automated anomaly detection system;
Reliability - towards rigorous benchmarking practice and the development of more explainable anomaly detection algorithms;
Generalizability - developing more robust and accurate models leveraging the foundation model paradigm and emerging reasoning abilities of LLMs.
