Bacterial Stress Response
Nov 7, 2018
Research
Summary
I started working on bacterial stress responses during my postdoctoral research at Rutgers University, I continue to focus on using computational evolutionary approaches to study various facets of pathogen biology including:
- delineating the molecular mechanism underlying a newly identified stress response operon in the tubercle bacterium involving the phage-shock-proteins (psp);
- unraveling the evolution of bacterial stress response systems (psp) across the tree of life using protein sequence-structure-function relationships;
- reconstructing and analyzing the mycobacterial sigma factor regulatory network.
