Jiang Liu

I am a Senior Applied Research Scientist in the AMD GenAI team. I received my Ph.D degree from Department of Electrical and Computer Engineering, Johns Hopkins University in 2024, advised by Prof. Rama Chellappa. I was awarded the Amazon AI2AI Fellowship in 2023. I received my BSE degree from Department of Automation, Tsinghua University in 2019 advised by Prof. Jianjiang Feng and Prof. Jie Zhou.

In summer 2023, I interned at Microsoft Azure AI with Dr. Jianfeng Wang working on multi-modal large language models. In summer 2022, I worked as an Applied Scientist Intern at Amazon AWS AI working on vision-language models mentored by Dr. Hui Ding, Dr. Zhaowei Cai, and Dr. Yuting Zhang. I've also worked as a Deep Learning Research Scientist Intern at Subtle Medical developing novel Transformer-based magnetic resonance imaging (MRI) algorithms.

Research

My current research interests include large language models, vision-language models, and trustworthy AI. I lead the development of Instella, a series of fully open language models at AMD.

We are hiring full-time research scientists and research interns in all areas of generative AI. Feel free to drop me an email with your CV if interested. Research collaborations are also welcome!
