معرفی
Aïssa Guesmia is a Maître de conférence (Associate Professor) at Université de Lorraine in Metz, France, where he has been working since 2001. He is affiliated with the Faculty of Mathematics, Computer Science and Mechanics (UFR MIM) and is a member of the Partial Differential Equations research team at IECL (Institut Élie Cartan de Lorraine). He also holds an Adjunct Professor position at King Fahd University of Petroleum and Minerals (KFUPM) in Saudi Arabia since 2019, following a two-year detachment as Associate Professor there from 2012-2014.
Dr. Guesmia received his Baccalauréat in Mathematics from Technicome de M'sila, Algeria in 1991. He earned his Maitrise (equivalent to Master's) in Functional Analysis from Ferhat Abbas University in Sétif, Algeria in 1995. He then pursued his DEA (Diplôme d'Études Approfondies) and PhD in Mathematics at Louis Pasteur University in Strasbourg, France, completing his PhD titled "Contributions to exact controllability and stabilization of evolution systems" in 2000 under the supervision of Professor Vilmos Komornik. He obtained his HDR (Habilitation à Diriger des Recherches) in 2006 with the thesis "Integral inequalities and applications to the stabilization of non-dissipative distributed systems."
Dr. Guesmia's research focuses on partial differential equations and control theory, particularly in the areas of existence, uniqueness and regularity of PDE solutions, observability and exact controllability, asymptotic behavior, integral inequalities, and numerical analysis. His work has significant applications in structural mechanics, including Timoshenko systems, wave equations, plate theory, and elasticity. He has developed innovative approaches for stabilizing non-dissipative distributed systems through the introduction of new integral inequalities and has made substantial contributions to understanding the stability of systems with memory effects and delays. His research bridges theoretical mathematics with practical engineering applications.
Analysis of Dr. Guesmia's recent publications (2017-2020) reveals a continued focus on stability analysis of various structural systems, particularly Timoshenko beams, Bresse systems, and plate equations. His work frequently examines the effects of viscoelasticity, thermal conduction, and memory effects on system stability. A notable trend is his investigation of logarithmic nonlinearities in viscoelastic systems and the comparison of different types of heat conduction (types I and III) in thermoelastic structures. His research demonstrates both theoretical depth and practical relevance to engineering applications, with over 63 publications and extensive international collaborations.
Dr. Guesmia has served as an Associate Editor for the journals Nonautonomous Dynamical Systems (since 2013) and International Journal of Mathematical Physics (since 2018). He has been a regular reviewer for Mathematical Reviews, American Mathematical Society since 2001. His professional qualifications include three successful qualifications for Professor positions (2007, 2012, and 2017) in section CNU 26.
Dr. Guesmia has supervised six doctoral theses, two magister theses, and several Master's theses across multiple countries including France, Algeria, and Lebanon. He has secured eleven research projects primarily funded by institutions in Saudi Arabia and Oman. His international collaborations are extensive, with regular teaching activities in Algeria through the Algerian-French doctoral school established in 2005, where he has conducted eight intensive M2 courses.
Dr. Guesmia is an active member of the Partial Differential Equations, Analysis and Applications research group at IECL. His international network includes ongoing work with King Fahd University of Petroleum and Minerals in Saudi Arabia, University of Maringà in Brazil, Lebanese University in Beirut, and multiple Algerian universities. He has participated in over 50 conferences worldwide and maintains a robust research program with continuous publications since 1997.
