Biography

Sanjay Aneja, MD is an Associate Professor within the Departments of Therapeutic Radiology, Biomedical Engineering, and Bioinformatics & Data Science at Yale School of Medicine. Dr. Aneja is a physician scientist whose research group is focused on the application of machine learning techniques on clinical oncology. He received his medical degree from Yale School of Medicine serving as class president. During medical school he completed a research fellowship at the Department of Health and Human Services in large scale data analysis. He later completed his medicine internship at Memorial Sloan Kettering Cancer Center followed by his residency in radiation oncology at Yale-New Haven Hospital. During his residency he completed his post-doc in machine learning at the Center for Outcomes Research and Evaluation (CORE) receiving research grant from IBM Computing. Has received research grants from the NIH, NSF, American Cancer Society, and other foundations.

The Aneja Labs on-going efforts include:

1) Deep Learning to Derive Imaging Based Biomarkers of Cancer Outcomes: We have previously shown the ability for deep learning to derive imaging-based biomarkers for lung, head/neck, and prostate cancers and are currently applying our deep learning platform to a variety of different other cancer types. We have developed a national consortium of institutions whom have contributed data to our effort. This project is funded by the NIH, AHRQ, Radiation Society of North America (RSNA), and the American Cancer Society.

2) Improving Efficiency of Deep Learning Algorithms on Medical Data: Our group has increasingly worked to develop more computationally efficient, stable, and cost effective methods for diagnostic image analysis.

3) Machine Learning Methods for Clinical Trial Classification: Our group, through a collaboration with SWOG and an industry partner, is studying the ability of machine learning to classify cancer clinical trials and match clinicians to relevant randomized clinical trials. This project is currently funded by the NSF and SWOG Hope Grant.
