Introduction:
The topic of my doctoral study focus on the effects of micro-physical processes on bacterial cell-to-cell or bacteria-phage interactions and their diversity patterns. Along this line, we have been developing an in-situ microscopic observation and individual-based modeling platform to quantify how micro-scale soil hydrophysical parameters and variations affect interactions and their coevolution.

Ph.D Topic: “Effects of soil micro-hydrophysical processes on microbe-phage interactions and diversity patterns”
Research focus:
ØUncover the game rules of bacteria and phage interactions in soil, and links to their diversity patterns
ØModeling the process of phage infection with host cells motility and growth
ØIsolation and identification of soil viruses
ØSurvey of soil virus diversity
Supervisior: Gang Wang
Master's Thesis: “Characteristics of deep sea microorganisms based on streak plate and high-throughput single-cell culture method”
Research focus:
ØEstablish a novel method for single-cell isolation of uncultured bacteria from marine samples by Flow Cytometer sorting system;
ØDeep analysis of diversity and information such as their morphological features, carbon assimilation and genome;
ØPolyphasic taxonomy of new species.
