  • Andrew William Chen, PhD

    • Postdoctoral Research Scientist

    My research areas include using radiomics to develop personalized medicine approaches for non-small cell lung cancer patients treated with immunotherapy. I am also researching how radiomics can be applied to 3D as well as 4D molecular images for patients with non-small cell lung cancer as well as breast cancer, and I am interested in methods to combine multiomic data.
