Yuhao Zhang

Hey there, welcome!

I am currently an NLP scientist at Amazon AWS AI, on a mission to deliver innovative and state-of-the-art AI/NLP services to enterprises and end users.

Before Amazon, I obtained my PhD degree from Stanford University, where I was jointly advised by Prof. Chris Manning in the Stanford NLP Group and Prof. Curtis Langlotz in the Stanford AIMI Center. My PhD work has focused on natural language processing and its applications in medicine.

Before that, I obtained a M.S. degree in the Computer Science Department at Stanford University, and a bachelor’s degree from the Department of Electronic Engineering at Tsinghua University, China.

research interest

I care about NLP systems and their impact in real-world applications. My research work has focused on four key areas:

information extraction, with a focus on understanding entities and relations in both general newswire and biomedical text;
text summarization, with a focus on improving the factual correctness of summarization systems;
multimodal learning, with a focus on joint modeling of medical images and text;
syntactic analysis and open-source NLP toolkit, and I am a co-author of the widely used Stanza NLP library.
