Riqiang Gao

CV / Scholar / Github

I have focused on artificial intelligence (AI) technologies since 2015 when I have worked on face recognition for my Bachelor thesis. During my Master's period (2015.09-2018.07) at Tsinghua University (research-oriented, 3-year program), I have continued working on face recognition topics, where I have devoted myself to machine learning, especially deep learning.

I'm working on AI for Healthcare as seinor AI scientist and project manager at Siemens Healthineers. I have been trained at Vanderbilt University from 2018.8 - 2022.3 as a Ph.D. student, where I mainly focus on medical imaging and informatics (specifically, lung cancer risk estimation). As the first author, I have won RFW All-conference Best Student Paper Finalist twice (2020, 2021) in SPIE Medical Imaging, and C.F. Chen Best Paper at Vanderbilt University.
