I am a BIG fan of microbes and imaging! Both my current lab's research and long-term career goal are devoted to microbiomics imaging. It primarily focuses on the development and application of cutting-edge optical imaging technologies complemented with state-of-the-art multi-omics approaches to gain a comprehensive understanding of host/microbe-microbe interactions that underpin microbiome-related human diseases.
My PhD research under Dr. Ji-Xin Cheng’s mentorship at Boston University focused on the development and application of label-free chemical imaging techniques to reveal hidden biomarkers in human diseases and human pathogens. Specifically, I achieved glycated hemoglobin quantification in single red blood cells using transient absorption microcopy as an innovative approach to diagnose Type 2 diabetes (Dong et al. Science Advances 2019) and deciphered mechanism of action of amphotericin B, the gold standard antifungal drug, using polarization-sensitive stimulated Raman scattering microscopy (Dong et al. Science Advances 2021). Driven by my ingenue curiosity on a serendipitously observed photobleaching phenomenon under transient absorption microscopy, I discovered two endogenous chromophores in human pathogens, staphyloxanthin and catalase, as the underlying molecular targets of antimicrobial photohterapy that are subject to photolysis (Dong et al. Advanced Science 2019; Hui#, Dong# et al. Advanced Science 2020; Dong et al. Advanced Science 2022; Dong et al. JCI Insight 2022). These findings have become breakthroughs for the field, and opened new translational opportunities to combat superbug infections (5 granted patents and a startup, Pulsethera, spun off for their clinical translation and commercialization).
Seeking more microbiology questions and trainings, I joined Forsyth Institute/Harvard School of Dental Medicine as a postdoc and switched my gear studying host/microbe-microbe interactions under the mentorship of Drs. Gary Borisy, Wenyuan Shi, and Xuesong He. By coupling optical imaging with multi-omics, I elucidated the role of intracellular lipid droplets in episymbiotic host-microbe interactions (Dong et al. The ISME Journal 2024) and identified and then developed a Fusobacterial RNA-binding protein as a novel class of host-derived antimicrobials for targeting colorectal cancer-causing Fusobacterium nucleatum (Dong et al. International Journal of Oral Science 2025; Yang#, Dong# et al. The ISME Journal 2023). While at Forsyth, I have particularly spearheaded the development of next-generation multiplex fluorescence in situ hybridization (FISH) imaging for interrogating microbiome atlas and host/microbe-microbe interactions. I developed an expansion microscopy-based multiplex FISH imaging technology (Dong et al. Proc. Natl. Acad. Sci. U.S.A. 2024) that enables the seamless integration of expansion-mediated single-cell functional imaging with biogeographic mapping. I further co-invented multiplex FISH probes and methods (Dong et al. manuscript submitted 2026) that allow high-throughput whole-mount imaging that was previously conceived impossible. These advances are expected to profoundly open new avenues for microbiome studies.
“Seeing is believing” and “Discovery can be made by simply watching”. This was how Antonie van Leeuwenhoek trailblazed the microworld using his microscope and became the father of microbiology. This is also why modern optical imaging plays an indispensable role in understanding host/microbe-microbe interactions, particularly considering their spatial, temporal, functional, and molecular resolving power in a complex environment. I am enthusiastic about leading my research team to advance new frontiers in microbiomics imaging.
Outside of my research, I love spending time with my daughter and husband, listening to music, traveling, cooking, and reading.

Graduate Students
Jayden Morrobel
Hi! I am Jayden, a first-year PhD student in Dr. Dong’s lab. I am particularly passionate about biophotonics, microbiome imaging, and innovative therapeutic strategies for infectious diseases. For my PhD research, I hope to help advance noninvasive and clinically translatable technologies that bridge engineering, biology, and medicine.
Outside of research, I enjoy combining leadership, teamwork, and discipline across different areas of my life. During my undergraduate studies at SUNY Purchase College, I played collegiate lacrosse, an experience that strengthened my work ethic, resilience, and ability to perform in team-oriented environments. I also have experience in leadership and business operations through co-managing an automotive service company. My long-term goal is to build a career that combines scientific innovation, translational research, and meaningful healthcare impact.
