Reference excerpt

María Fernanda Ceriani is an Argentine biologist. She studies the neuronal mechanisms involved in the regulation of circadian rhythms, using Drosophila melanogaster as a biological model. She is the president of INIS Biotech, heads the Behavioral Genetics Laboratory at the Leloir Institute Foundation, and is a researcher with the National Scientific and Technical Research Council (CONICET). Ceriani received her PhD from the University of Buenos Aires and did postdoctoral research at the Scripps Research Institute. She won a L'Oréal-UNESCO For Women in Science Award in 2011.

Early life and education María Fernanda Ceriani was born on 26 May 1966 in Ramos Mejía, Argentina. She graduated from the Escuela Nacional Normal Superior Manuel Dorrego in 1983. Ceriani attended the Faculty of Exact and Natural Sciences of the University of Buenos Aires, earning her MSc in biology in 1990 and a PhD in biological sciences in 1996. She started her doctorate with Esteban Hopp at the Institute of Biotechnology of the National Agricultural Technology Institute in Castelar, and continued research in Roger N. Beachy's laboratory at Scripps Research in La Jolla, California. She was a postdoctoral fellow at Scripps Research, working in the laboratory of chronobiologist Steve A. Kay from 1997 to 2002. She then returned to Argentina, where she was selected in a contest to repatriate researchers to start a laboratory at the Leloir Institute Foundation.

Scientific career Ceriani studies the neuronal mechanisms involved in the regulation of circadian rhythms. She principally works with Drosophila melanogaster as a biological model and employs behavioral experiments and immunohistochemistry. She has authored papers with Michael Rosbash and has written about circadian plasticity in Drosophila. Ceriani is the president of INIS Biotech, the technology liaison office of Leloir Institute, and has headed the Behavioral Genetics Laboratory at the Leloir Institute Foundation since 2002. She is also a researcher with the National Scientific and Technical Research Council (CONICET) and has membership in the Latin American Academy of Sciences as of 2019. In 2021, she was appointed a member of European Molecular Biology Organization as principal investigator of the Institute for Biochemical Research at CONICET. Ceriani received the national L'Oréal-UNESCO For Women in Science Award in 2011. She received a Konex Award in 2013. Ceriani's laboratory received funding from the National Institutes of Health in 2020 for a research collaboration with universities in California and Washington to describe structural changes of clock neurons that regulate the circadian rhythms in the brains of mice and Drosophila flies. Following the COVID-19 pandemic, Ceriani was part of a group of researchers from CONICET studying the impact of social isolation on circadian rhythms in 2021. She was a project leader in the development of Mi Reloj Interno, an app for monitoring the rhythms.

Personal life Ceriani has three children, two of whom are twins.

Worked examples

Example 1 — a first encounter with María Fernanda Ceriani

Start with the simplest possible case. Write down what María Fernanda Ceriani 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 María Fernanda Ceriani 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 María Fernanda Ceriani 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 María Fernanda Ceriani

In research: María Fernanda Ceriani 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 María Fernanda Ceriani 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: María Fernanda Ceriani is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, 20th-century Argentine biologists, 20th-century Argentine women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for María Fernanda Ceriani 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.
