Azzedine Bousseksou (born December 2, 1964) is a Franco-Algerian physical chemist who specializes in molecular materials and spintronics. His research focuses on the development of functional molecular materials for applications in memory storage, sensors, and optoelectronic devices. Bousseksou's work has contributed to the study of spintronics phenomena, molecular electronics, and nanotechnology.

Education

Azzedine Bousseksou received a diploma in Materials Physics from Université de Bab Ezzouar (Algiers) in 1983. He earned a Diplôme d'études approfondies (DEA) in Materials Science from the University of Nantes in 1988 and a PhD in Materials Science from Pierre and Marie Curie University (Paris) in 1992. His doctoral research was conducted at the Inorganic Chemistry Laboratory of Johannes Gutenberg University Mainz.[1]

Career

Bousseksou began his career in 1993 as a research fellow at the Coordination Chemistry Laboratory (LCC) of the French National Centre for Scientific Research (CNRS), based in Toulouse.[1][2] In January 2003, he founded and led the Switchable Molecular Materials research team at LCC-CNRS Toulouse, while serving as a research director.[3] From 2006 to 2009, he directed the GDR Magnétisme et Commutation Moléculaire. He also co-coordinated the France-Japan GDRI on multifunctional molecular materials between 2006 and 2010. From 2011 to 2013, he was Deputy Director of the LCC-CNRS Toulouse, becoming its Director in 2013.[4]

Bousseksou was a member of the CNRS national committee for the evaluation of researchers and research laboratories from 2000 to 2004 and from 2010 to 2015. He has been a member of the European Network of Excellence on Molecular Magnetism, REX MAGMANET,[5] and the European Institute on Molecular Magnetism (EIMM).

Bousseksou’s research centers on molecular materials and spintronics, focusing on spin-transition phenomena.[6] His team developed an Ising-type model to describe one- and two-step spin-tranansitions, predicting symmetry breaking.[7] They demonstrated magneto-switching in spin-transition molecules using intense pulsed magnetic fields and investigated the underlying nucleation and growth dynamics.[8] The group reported hysteresis in the dielectric constant of spin-transition complexes and observed double photo-switching in binuclear compounds, as well as photo-switching behavior at room temperature.[9][10][11] They synthesized spin-transition thin films and coordination nanoparticles (approximately 4 nm) exhibiting hysteresis near room temperature,[12] and developed hybrid systems[13] combining spin-transition and fluorescence to study single nano-objects.[14][15] Recent works include applying spin-transition materials in photonic[16] and plasmonic devices,[17] gas sensors,[18] nano-thermometers,[16] and nanoelectronics.[11][19][20][21] The team also explored the use of these materials for direction-controlled micro- and nano-actuation, leading to prototypes of artificial muscles responsive to thermal or optical stimuli.[22][23][24][25][26]

Bousseksou is a founding member of the Algerian Academy of Sciences and Technologies (2015). He is also a member of the French Academy of Sciences (2013),[27] the European Academy of Sciences and Arts (2012), and the European Academy of Sciences (2014).
