Ad for a postdoc position in centromere biology with colorful chromosomes and centromeres made out of FIMO.

🧪 My lab has an opening for a postdoc position soon! Please share/get in touch!

Mitosis has a timing system. If chromosomes attach properly, cells divide on schedule and keep proliferating. If attachment is slow or incomplete, the delay is recorded — and daughter cells stop dividing.
We explore this link in our new preprint.

PhD position in my lab!

PAF15–PCNA exhaustion governs the strand-specific control of DNA replication Nature - PCNA–PAF15 has a key role in determining replisome dynamics during genome replication and protecting against genome instability.

Dear Colleagues,

Delighted to share that our first lab paper is now published in Nature.!!! 😊😊😊

We identify a previously concealed “safety limit” in DNA replication program: cells intrinsically rate-limit PCNA via PAF15, shaping strand-specific and global replication dynamics.

New preprint from the lab 🎉: γ-tubulin is a novel target of the tubulin autoregulation pathway! Previously thought to exclusively target α- and β-tubulin mRNAs, we show that the TTC5–SCAPER–CNOT11 axis also degrades γ-tubulin mRNA, expanding the scope of this fundamental regulatory mechanism.

For decades, we’ve known cells dismantle & rebuild the nuclear envelope in sync with spindle poles. But why does this coordination matter? And how do pole material properties ensure error-free division?
