Ruizhe Pei

PhD Researcher


My main research interest is biotechnology related topics. I am passioned about engineering the microbial ecosystem to contribute to waste valorization. I am interested in not only the bioprocess but also the dynamics of microbial population. Currently, I am studying recovering biopolymers (PHAs) from WWTP and visualizing the dynamic of microbial population.
