Research Interests:

Telomeres & telomerase and their roles in cancer and stem cell diseases; Structural, biochemical and molecular genetic analyses of nucleoprotein assemblies

Telomeres are closely involved in stem cell differentiation and cancer cell proliferation. Our long-term goal is to reveal new mechanisms for telomere length regulation and chromosome end protection. Therefore, valuable targets for mechanism-driven design of cancer and anti-aging therapeutics may be identified through our research.

Specifically, we are interested in:

• Regulation of telomere homeostasis from atomic level to system level using the integration of biochemistry, structural biology (especially, x-ray crystallography), and genetics approaches.

• Re-engineering/re-wiring telomere regulatory pathways using synthetic biology modules and concepts.

• Chemical biology approach to identify small molecules that can inhibit telomere ON/OFF transition thereby inhibiting cancer cell progression.
