As a physician-scientist being involved in the clinical care of pediatric patients and developing novel imaging technologies in a basic science lab, my goal is to link the fields of Nanomedicine, Cell Biology and Medical Imaging towards more efficient diagnoses and image-guided therapies. Our research team successfully translated numerous nanomedicine technologies from preclinical research concepts to clinical applications, thereby creating direct value for our patients.

Edwin Chang, PhD

Edwin Chang, PhD

Director of the Preclinical Imaging Facility at the Canary Center

I previously worked at Geron Corporation (Menlo Park, California) where I studied the mechanism of cellular immortalization and cellular aging with the goal to develop new therapies against cancer. I joined Stanford University in 2002 and the Molecular Imaging Program at Stanford (MIPS) in 2009, where I explored the applicability of various modalities (PET, BLI, CT, MRI, US) for many projects related to cancer under the leadership of Sanjiv Sam Gambhir. Most recently, I joined the Daldrup-Link lab where I continue to investigate new cell therapies for the treatment of glioblastoma with multi-modality imaging techniques.

Radiologist

As a radiologist and clinical scientist, I am interested in the development, translation and clinical validation of new medical imaging techniques. My research interests revolve around vascular and oncologic imaging, with particular emphasis on the study of novel MRI techniques, radiomics, and computer vision. I conducted research in molecular MRI and investigated the development and evaluation of methods to improve visualization of the extracellular matrix. I also evaluated quantitative MRI sequences, particularly with respect to their suitability for renal and prostate oncologic imaging, and applied methods from the fields of radiomics and artificial intelligence to improve the diagnostic value of radiologic imaging.

Shakthi Kumaran Ramasamy

Shakthi Kumaran Ramasamy, MD

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.
