We seek to develop and apply technologies (particularly revolving around high-dimensional tissue imaging) to address questions related to host-disease interactions in their native tissue context. By combining these methodologies with a systems approach to compute higher-order host-disease interactions, our ultimate goal is to understand disease mechanisms with the long-term goal of improving therapeutics. The lab is broadly focused on 3 main areas: “Viral Pathogenesis”, “Cancer Biology” and “Immune Dysregulation”, with the intention to learn fundamental principles that can be cross-applied between these pillars of research.


Sizun Jiang completed his Ph.D training at Harvard University, where he made significant strides in the field of host-pathogen chromatin interactions during viral-driven lymphomagenesis under the guidance of the late Prof. Elliott Kieff. He then moved to Stanford to work with Prof. Garry Nolan to develop and apply groundbreaking spatial technologies to better understand biological systems. Currently, as an Assistant Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, Dr. Jiang’s research stands at the forefront of innovation, focusing on the intersection of host-disease interactions through the development and application of novel spatial technology platforms and computational algorithms. His ongoing work delves into the intricacies of viral pathogenesis, tumor biology, and immune dysregulation.
