Biography: Dr. Castro is a translational oncologist with experience leveraging nanotechnology and molecular imaging for solid tumor detection and serial profiling across diverse clinical specimens. He has served as Chair of the In Vitro Diagnostics Working Group within the NCI Alliance for Nanotechnology in Cancer. Currently, he is Director of the Cancer Program within the MGH Center for Systems Biology and a faculty member at Harvard Medical School. Dr. Castro graduated from the University of California, Berkeley where he received both his BA and MSc. He attained his MD degree from the UCSF School of Medicine where he also completed Internal Medicine residency training. Dr. Castro completed an adult oncology fellowship from the Dana-Farber / Partners Cancer Care program. During this period, he also received a MMSc from Harvard Medical School. His research work is supported by NIH, DOD, and non-profit cancer foundations.

Research and Expertise: We are interested in developing, optimizing, and testing novel nanosensors (magnetic or surface plasmon resonance based) to detect circulating tumor cells or exosomes across clinical specimens. We provide additional expertise in lending biological and translational relevance to emerging technologies within our labs. We can readily pivot to specimens attained under the context of clinic trials to explore novel biomarkers, using our nanosensing platforms, as potential pharmacodynamics readouts. Additionally, we recently established low tech yet robust cancer diagnostic technologies for use in resource limited regions throughout the world.
