Research
Our lab is interested in chromosome dynamics in bacteria. Using Bacillus subtilis as a model organism, we combine genetic, molecular, cytological, and biochemical approaches to study how the chromosome is organized and segregated during the cell cycle. Our research primarily focuses on a set of highly conserved factors in chromosome biology, including the parABS partitioning system and the SMC condensin complex. Taking the many strengths of studying bacteria, our goal is to uncover general principles of chromosome organization and segregation in living organisms. Specific research directions include:
- Chromosome organization and segregation during the replication cycle
- Identification and characterization of novel factors involved in chromosome biology
- Molecular mechanism of chromosome packaging
- Chromosome folding during growth and development
Research areas
Chromatin, Chromosomes, and Genome Integrity
