Brian Ji , a combined MD/PhD student in Columbia’s Department of Systems Biology, delivered the winning oral presentation at the recent Biennial Integrated Program Retreat. Ji, who is a member of the Vitkup Lab, presented “Quantification of Human Gut Microbiota Variability Using Replicate Sampling,” and was one of six systems biology graduate students who delivered research presentations at the conference. 

Ji discussed a novel experimental and computational method he has developed to understand spatiotemporal dynamics of the human gut microbiome, as well as the technical noise tied to current human microbiome sequencing techniques. In addition to the human gut, the method, he says, is broadly applicable to other bacterial ecosystems and other sequencing-based studies. In the Vitkup Lab , Ji works on developing and utilizing quantitative approaches to reveal novel biological insights into bacterial ecology as well as cell physiology. His research interests also include exploring computational models and tools to study cancer metabolism at a global scale. In 2011, Ji received a prestigious Barry Goldwater Scholarship for his work on mathematical modeling to study impaired brain connectivity in epilepsy.
