About

Challenges to DNA replication, called replication stress, pose major risks to genome fidelity. Our lab studies the molecular mechanisms of various replication-coupled machines that help achieve accurate and efficient chromosome duplication in the face of such stress. Current research topics include the replication checkpoint apparatus, replication-coupled translesion synthesis, and conflicts between replication forks with transcription bubbles and other R-loop proteins. We study these molecular mechanisms in detail with single-molecule fluorescence techniques, traditional biochemistry, genetics, and cell biology.

I currently teach BC404 (Comprehensive Biochemistry Lab) as well as sections in BC563 (Molecular Genetics) and BC512 (Principles of Macromolecular Structure)
