Reference excerpt

Mario Barbatti (born December 28, 1971) is a Brazilian physicist, computational theoretical chemist, and writer. He is specialized in the development and application of mixed quantum-classical dynamics for the study of molecular excited states. He is also the leading developer of the Newton-X software package for dynamics simulations. Mario Barbatti held the Amidex Chair of Excellence at Aix Marseille University between 2015 and 2019, and has been a professor there since 2015.

Honors and awards 2026: Senior member of the Institut Universitaire de France. 2021: Fellow of the European Academy of Sciences. 2021: Senior member of the Institut Universitaire de France. 2019: Opening lecture of the XX Brazilian Symposium of Theoretical Chemistry. 2019: ERC Advanced Grant. Mario Barbatti has been the first Brazilian scientist and the first computational chemist in France to receive this research grant. 2015: A*Midex Chair of Excellence.

Scientific contributions, interests, and production By the end of 2025, Mario Barbatti had published over 200 scientific works, which had been cited about 16000 times (h-index 65). Since 2007, Barbatti has been the leading developer of the Newton-X platform, a software collection for dynamics and spectrum simulations, using surface hopping and the nuclear ensemble approach. Using dynamics and other quantum chemical methods, his research has focused on simulations of the ultrafast photochemistry and photophysics of organic molecules. Among his main contributions, Barbatti, in collaboration with Hans Lischka, delivered a comprehensive map of the internal conversion channels of nucleobases. These results help to explain how DNA is stabilized after UV excitation. Although Barbatti's research has been strongly oriented towards photoinduced processes in nucleic acids, he and his co-workers have contributed to many different sub-fields. In 2013, in collaboration with Walter Thiel, they showed how UV irradiation can generate nucleobases out of inorganic components. Although this chemical reaction has been known since the 1960s, their work was the first one to unveil the exact reaction mechanism. Barbatti also discovered a new internal conversion mechanism, allowing molecules to quickly return to the ground state. In this mechanism, a conical intersection between the ground and the excited electronic states is formed by an electron transfer from the solvent to the excited chromophore. This solvent-chromophore electron-transfer mechanism has been predicted to occur in 7H-adenine in water. Barbatti and his colleagues at the Federal University of Paraiba have shown that CH...Cl hydrogen bonds can be formed in small molecules in the gas phase. This type of bond had previously been observed only in densely packed crystal structures. He has also contributed on topics in organic photodevices, astrochemistry, and atmospheric photochemistry. Currently, Barbatti and his team—the Light and Molecules group —are focusing on method developments, attempting to extend the excited-state simulation methods into the nanosecond regime. In a collaboration with Pavlo Dral and Walter Thiel, they implemented one of the first algorithms for nonadiabatic dynamics using machine learning.

Popularization and presence in the media Some of the main results from Barbatti's work have been picked up by diverse news outlets. These media have dedicated special attention to his research on internal conversion of nucleobases, prebiotic reactions, and new chemical reactions and mechanisms. His work is also popularized through blog posts on his group website and YouTube channel.

Worked examples

Example 1 — a first encounter with Mario Barbatti

Start with the simplest possible case. Write down what Mario Barbatti claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Mario Barbatti 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 Mario Barbatti 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 Mario Barbatti

In research: Mario Barbatti appears in chemistry 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 Mario Barbatti 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: Mario Barbatti is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, Academic staff of Aix-Marseille University, Brazilian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Mario Barbatti 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.
