Mr. Nakatsu is currently a final-year doctoral candidate among members of Professor Jun Yu's research team at the Department of Medicine and Therapeutics and the Institute of Digestive Diseases in the Chinese University of Hong Kong. His doctoral work focuses on understanding and harnessing the role of intestinal microbiota in colorectal cancer (CRC) pathogenesis, detection, prognostication, and treatment. One of the greatest challenges in the field of CRC microbiome research has been to uncover mechanisms of interaction among members of the gut microbiota that shape the structural and functional heterogeneities of microbial communities associated with the clinical outcome of CRC patients. He addresses this question in systems biology by integrating trans-kingdom taxonomic profiles into building a broader picture of the microbial kingdoms in CRC. Ultimately, the goal of his research is to identify metagenomic origins of CRC-associated oncomicrobes for leveraging the disease model applications of microbiome analysis.

Microbial communities colonizing human and other organisms carry out important functions in the physiology of hosts, including metabolism, immune functions and affect the health of host. During my PhD and post-doc research, I have investigated the fundamental shaping forces of microbiome diversity in wild mice model as well as humans. In European wild mice, I have demonstrated that biogeography, diet and genetic all have profound effect on the composition and functionality of gut microbiome, and host forms an evolutionary entity with their microbiota (Linnenbrink and Wang, 2013 Mole Ecol; Wang 2014 PNAS; Wang 2015 Nat Comms). With large population studies, I have built novel statistical models to explore comprehensive environmental influences on the individuality of gut microbiome (Falony, Joossens, Viera-Silva, Wang 2016 Science), and carried out one of the first genome-wide-association study on human microbiota (Wang, Ithingholm, Skiecevičienė 2016 Nat Genet). And lastly, I have revealed the important gene-microbiome cross-talk in critical disease models, pinpointing microbiome as important mediator or direct cause in disease manifestation, and conversely could be used for treatment (Moschen, Gerner, Wang 2016 Cell Host Microb; Peuker & Muff 2016 Nat Med, etc.).
