Douglas Ballon

Douglas Ballon is a Professor of Physics in Radiology at Weill Cornell Medical College and Professor of Genetic Medicine. He serves as the Founding Director of the Citigroup Biomedical Imaging Center (CBIC), a comprehensive $80 million imaging facility supporting nearly 100 investigators from 15 academic institutions. His work bridges physics, radiology, and genetic medicine with a focus on developing quantitative imaging biomarkers for applications in gene therapy and neurodegenerative diseases.

Ballon received his Ph.D. in experimental nuclear physics from Rutgers University in 1985 and completed postdoctoral work in medical physics at Memorial Sloan Kettering Cancer Center from 1985-1988. He joined the faculty at Sloan Kettering before moving to Weill Cornell in 2001 to establish the Citigroup Biomedical Imaging Center.

His research primarily focuses on developing quantitative imaging biomarkers for genetic medicine applications, particularly for studying viral vector biodistribution in gene therapy and measuring whole-body immune responses. His laboratory has pioneered techniques for non-invasive biomarker panels for CLN2 disease (a pediatric neurodegenerative disorder), developed methods for monitoring adeno-associated viral vectors using radioiodination and PET imaging, and created MRI techniques for bone marrow hematopoiesis studies. His work has significant implications for improving gene therapy delivery systems and monitoring therapeutic responses in neurodegenerative conditions.

Analysis of Ballon's recent publications reveals a strong focus on viral vector biodistribution tracking using PET imaging, development of imaging biomarkers for neurodegenerative diseases (particularly CLN2/Batten disease), and innovations in MRI hardware and techniques. His work consistently bridges basic physics principles with clinical applications, demonstrating translational impact from laboratory techniques to human therapeutic monitoring.

Ballon leads a research group developing imaging techniques for genetic medicine applications. His lab has secured significant NIH funding including R01 EB027918 for rapid non-invasive whole-body imaging of gene transfer vectors, U54NS065768 for CLN2 disease biomarkers, and R01EB002070 for bone marrow hematopoiesis studies. His team includes research associates, postdoctoral fellows, and graduate students working on MRI coil development, viral vector tracking, and biomarker validation.

The Ballon Laboratory within the MRI Research Institute (MRIRI) focuses on developing quantitative imaging biomarkers for genetic medicine, with particular emphasis on studying viral vector biodistribution in gene therapy and measuring whole-body immune responses. The lab has achieved several 'firsts' in imaging techniques and maintains strong collaborations with the Sloan Kettering Institute through the Graduate School of Medical Sciences partnership.
