Negar Arabzadeh
Postdoctoral Fellow at UC Berkeley
This is Negar Arabzadeh. I am a postdoctoral researcher at UC Berkeley, working with Professor Matei Zaharia. I completed my PhD at the University of Waterloo, where I was advised by Dr. Charles Clarke. My research lies at the intersection of information retrieval and the evaluation of—and with—large language models (LLMs) in information access systems.
