Postdoctoral Research Fellow

I am interested in clinical and translational research to investigate new immunotherapies for osteosarcoma and nanoparticle labelled CAR-T cell therapy for GBM. Therapeutic CAR-T cells face a distinct set of hurdles in the therapy of solid tumors, that does not present in hematopoietic malignancy. My goal is to establish real-time clinical-imaging techniques for image-guided immunotherapy of CAR-T cells and regionally deliver them to the tumor microenvironment through a catheter or direct needle-based injection approach and get those cells where they needed to be! I also work on PET/MR imaging of stem cell transplants in arthritic joints and novel whole-body PET/MR imaging studies for monitoring cancer therapy response in pediatric cancer patients.

Manoj Kumar

Manoj Kumar, PhD

Postdoctoral Research Fellow

My curiosity is in visualizing the biological characteristics of malignant tumors using non-invasive imaging approaches such as PET and MRI. These imaging modalities enable imaging-guided treatment identifying the molecular signatures of cancer, thus individually tailoring treatment plans for patients. During my doctoral training, I developed a PET imaging approach to evaluate endocrine therapy responses in breast cancer. Since then, I have expanded my research interest to a variety of other solid cancers, including prostate cancer and bone sarcomas. My current research focuses on assessing immunotherapy response by visualizing tumor immune markers. The ultimate goals are to develop new PET and MR imaging probes and more effective immunotherapy approaches for image-guided cancer therapies. To achieve this, I am presently employing antibody-based PET imaging and therapeutic strategies to modulate immune functions and restore the suppressed immune response against cancer cells. I collaborate with interdisciplinary scientists focused on translating preclinical findings into clinical studies. My long-term goal is to be an independent translational scientist focused on developing new imaging and therapeutic strategies in cancer.
