Biography

Advised by Professor Daphne Ippolito, my Ph.D. thesis research currently explores on the topics of LLM Security and Adapters.

Previously at Cornell, advised by Professor Thomas Ristenpart, I had concentrated my master thesis on End-to-End Encryption applications in my security research. My research aims to enhance online community governance and privacy while balancing anti-abuse.

In my NLP work during my undergraduate and master degree, guided by Professor Claire Cardie, my focus was on improving Information Extraction and model interpretability, particularly when inputs are at the document level.
