Governance

Here you will find information regarding the governance of IHP and its organization together with a contact list.

Governance

The Institut Henri Poincaré has two sorts of legal status and two supervisory institutions, namely the CNRS and Sorbonne Université. Its director, a mathematician, was appointed by the Minister of Higher Education, Research and Innovation, and by the CEO of the CNRS on the recommendation of the IHP Board. Its deputy director, a physicist, was appointed by the director after advice from the Board.


The management team is composed of a director, a deputy director and a secretary general, assisted by an executive assistant.

Prof. Dominique Mouhanna, director of the Institut Henri Poincaré.

Dominique Mouhanna was appointed deputy director of the Institut Henri Poincaré as of May 1, 2021 until the end of Sylvie Benzoni's term. He took over from Rémi Monasson who was deputy director for three years.
Dominique Mouhanna holds a professor position at Sorbonne Université where he works in the Laboratory of Theoretical Physics of Condensed Matter. He is the head for Sorbonne Université of the international master  “Physics of Complex Systems”. His research activity and his teaching mainly relate to Theoretical Physics and Mathematics. More specifically, Dominique Mouhanna works on frustrated magnetic systems, disordered magnetic systems as well as on fluid and polymerized membranes, using perturbative and non-perturbative renormalization techniques.

Prof.  Sylvie Benzoni, former director of the Institut Henri Poincaré

Sylvie Benzoni is a former student of the École normale supérieure of Saint-Cloud who earned a phD in mathematics in 1991. She then became a CNRS full-time researcher in 1992. She has held a professor position at Université Claude Bernard Lyon 1 since 2003. She was director of Institut Camille Jordan for two years in 2016 and 2017, after having served as deputy director for five years. She has been director of the Institut Henri Poincaré since January 1st, 2018.
Sylvie Benzoni's research themes concern systems of partial differential equations for wave propagation and the modelling of complex fluids, such as those involving phase transitions. Her work focuses in particular on the stability of certain nonlinear waves.
She is committed to the transmission of mathematics through teaching and outreach.
Finally, she is engaged in "(truly) open access" scientific publishing.

Mme Annabelle Ostyn, secretary general of the Institut Henri Poincaré

Research engineer at Sorbonne Université since 2015, she was appointed Secretary general of the Institut Henri Poincaré on 1 March 2025.

Following the departure of Sylvie Benzoni on 1st January 2025, Dominique Mouhanna is temporarily managing the institute.

Boards

IHP Board has 15 elected members and around twenty appointed or permanent guest members representing the supervisory authorities, the ministry of higher education and research, local authorities and the scientific community. Its role is to ensure that the specific vocation of IHP is respected and to establish the operating and development policy of IHP.
