An ovarian follicle poised for ovulation, with the oocyte at its centre. Cell membranes are shown in orange and DNA in blue.

How does an ovarian follicle remodel in space and time to release an egg? 💥🥚

We have an exciting PhD project combining follicle culture, advanced imaging and quantitative analysis to understand the cellular dynamics of ovulation. 🔬

Polar chromosomes are rescued from missegregation by spindle elongation-driven microtubule pivoting - Nature Communications Polar chromosomes in human cells are prone to late alignment and segregation errors. Here, the authors show that spindle elongation rescues them by repositioning astral microtubules via a pivoting mec...

The project I contributed to during my master’s is officially out! 🎉
This work was led by my amazing mentors Valentina and Isabella, in the lab of @ivatolic.bsky.social.

Mitotic spindle will forever be my favourite subcellular structure. (Sorry Christopher!😂)

Bubble ovaries Christmas lab meeting! 🫧🦑

I am excited to be a part of the ovary lab in Marseille. Looking forward to the journey ahead. 🇫🇷🥳 #ovulation #PhD


1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

Pleased to share my new review:

Ovulation: A cellular symphony in three movements 💥🥚

Ovulation is more than egg release—it's a tightly regulated, tissue-scale process. Here, I present a temporal framework structured as a symphony performed by the cells of the follicle.
