Hong Zhao, MD, PhD, is an Associate Professor of Medicine at the Houston Methodist Academic Institute and Co-Director of the Advanced Cellular and Tissue Microscopy Core Facilities at the Houston Methodist Research Institute and the Houston Methodist Neal Cancer Center. Her research program focuses on defining how tissue-specific microenvironments govern cancer progression, neurodegeneration, therapeutic resistance, and clinical outcomes, with particular emphasis on brain metastasis and other biologically aggressive, treatment-refractory malignancies.

Dr. Zhao integrates cancer biology, neuroscience, advanced optical imaging, spatial and single-cell omics, and computational modeling to dissect tumor–microenvironment interactions across molecular, cellular, and spatial dimensions. Trained at Harvard Medical School and Houston Methodist, she has established a mechanistically grounded research program that has uncovered critical and previously underappreciated roles of brain-resident astrocytes, microglia, and oligodendrocytes in metastatic adaptation, immune regulation, and response to therapy.

By coupling multi-scale, high-resolution imaging with spatiotemporal molecular profiling and predictive computational frameworks, Dr. Zhao’s team systematically maps cell–cell communication networks within tumor and neural microenvironments. This strategy enables the identification of actionable signaling nodes and regulatory programs that drive disease progression and therapeutic resistance, providing a rational foundation for target discovery and therapeutic intervention.

These interdisciplinary efforts have yielded patented molecular diagnostic strategies, drug-repositioning approaches leveraging clinically available agents, and biologically informed combination therapies, several of which are advancing toward translational and clinical application. Dr. Zhao’s work has been published in leading journals, including Science Translational Medicine, Cancer Cell, Stem Cells, Cancer Research, Clinical Cancer Research, and Trends in Immunology, and has been continuously supported for over a decade by the NIH, the Department of Defense, and multiple foundations. Through her research and core leadership, Dr. Zhao aims to bridge fundamental mechanism with precision oncology to improve the prediction, prevention, and treatment of metastatic disease.

Dr. Zhao's research uses systems biology approaches to study and combat brain metastatic cancer. Her projects integrate "dry lab" computational modeling with "wet lab" experimental testing to discover effective  treatment strategies and explore personalized drug combinations.
