Members: Sara Ranjbar

I joined the PNT lab in 2018 as a postdoctoral research fellow specifically focusing on devising analytics tools using artificial intelligence, deep learning, and computer vision techniques to improve brain tumor patient’s care. My graduate work was related to the design and implementation of a biomedical texture analysis platform that uses ‘radiomics’ features for high-throughput generation of potential image-based biomarkers. Several of my publications demonstrated the potential application of radiomics features along with machine learning techniques in the diagnosis of breast cancer, head and neck cancers, as well as Alzheimer’s disease.

Outside of work I enjoy playing sand volleyball and pointless conversations about social issues.
