Cyrille Rossant, a matheux in face of justice

For six years, this neuroscience and data engineer researcher is plunged into scientific studies on shaken baby syndrome that his son had been the victim. He climbs to the niche in the face of what he considers bad science, resulting in a diagnostic drift.

Faced with their child’s disease or a parent, some scientists completely redirect their career, to try to advance science in the field that affects their loved one. After her son’s problem, put on her more cap. For six years, in parallel with his activities as a neuroscience and data engineer researcher, Cyrille Rossant has been involved in shaken baby syndrome (SBS). A thorny theme, because relating to mistreatment, in which he puts all his rigor and tenacity. Its objective: to demonstrate that the scientific data on which the diagnostics of SBS are based – increasingly systematic in front of certain brain injury of infants – are not so reliable, and that other medical causes are obscured.

“that so poor quality science can have such a great impact on children and their families is not acceptable”, summarizes Cyrille Rossant, who has presided over 2020 an association, Adikia (” injustice “in Greek), in contact with hundreds of parents and childminders saying Victims of false accusations of mistreatment.

In France, some 400 cases of SBS are diagnosed each year, a number which would have doubled in the Paris region during the pandemic, according to a recent study.

After five years of exchanges with him on this subject, during which he never put himself forward, we wanted to see him in his lab, to apprehend his other daily life. Missed. For nine years, he has full time. Affiliated with the Institute of Neurology of the University College of London (UCL), which hired him after his postdoc, in 2012, the 36 -year -old researcher officiates more precisely within the international Brain Laboratory (IBL). “It is a collaboration of around twenty neuroscience laboratories, on the model of what is done in physics,” he explains, seated on the world’s terrace, punctually drawing his smartphone to check information, bring A precision…

virtual laboratory

In this large virtual laboratory, which studies the neural circuits at stake in decision -making and adaptation behaviors, half of the researchers are experimenters who record the electrical activity of mouse neurons under the same experimental conditions, And the other half of the “matheux” that exploit the gigantic quantities of data generated. At the interface, the technical team of which Cyrille Rossant is part of the software infrastructure, for the analysis and visualization of these data.
