Reference excerpt

Marie-Hélène Verlhac is a French cellular biologist, specialising in the final stages of oocyte development. She was the recipient of the French National Centre for Scientific Research's (CNRS) Silver Medal in 2021. Verlhac has been the director of the Center for Interdisciplinary Research in Biology (CIRB) (French: Centre interdisciplinaire de recherche en biologie) since 2019, and the president of the French Society for Cell Biology (SBCF).

Life and career In 1988, Verlhac began her studies at the Ecole Normale Supérieure de Lyon. She graduated from Université Pierre et Marie Curie (UPMC) with a Master in Cellular and Developmental Biology in 1991, followed by a PhD in cellular and molecular biology in 1995, under the supervision of Dr. Bernard Maro. Her PhD studies also included a year studying under Prof. Hugh Clarke at McGill University. She undertook postdoctoral studies with Rik Derynck at the University of California, San Francisco. Verlhac returned to France and became a principal investigator of her own lab in 2002, which researches oocyte mechanics and morphogenesis. Oocytes, the female gametes, divide asymmetrically so that maternal stores can be preserved for the embryo's development; Verlhac's lab uses genetics, two-hybrid screening, and live imaging combined with biophysics to study such divisions. In particular, her lab has discovered the mechanisms underlying the positioning of the nucleus and spindle in oocytes. Verlhac was appointed deputy director of the CIRB in 2013, and then Director in 2019.

Worked examples

Example 1 — a first encounter with Marie-Hélène Verlhac

Start with the simplest possible case. Write down what Marie-Hélène Verlhac claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Marie-Hélène Verlhac before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Marie-Hélène Verlhac ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Marie-Hélène Verlhac

In research: Marie-Hélène Verlhac appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Marie-Hélène Verlhac in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Marie-Hélène Verlhac is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century French biologists, 21st-century French women scientists, Academic staff of the Collège de France, so understanding it makes those chapters shorter.
In everyday life: Look for Marie-Hélène Verlhac outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
