Antoine Lemenant is a Full Professor at Université de Lorraine (Nancy, France). He holds an IUF (Institut Universitaire de France) membership since 2023. His research focuses on calculus of variations, geometric measure theory, and partial differential equations, with applications to fracture mechanics and optimal design. He has held positions at University Paris 7 (2010-2018) and was a postdoc at the Centro De Giorgi in Pisa (2009-2010). He completed his PhD at Université Paris-Saclay under Guy David in 2008. Key research interests include: Energy minimization problems (Griffith energy, optimal compliance) Regularity theory for free boundaries and crack sets Numerical methods for geometric optimization Spectral optimization and domain perturbations His recent work (2023-2025) explores regularity properties of Griffith almost-minimizers, optimal design of elastic structures, and phase-field approximations of minimal surfaces. He has co-authored over 40 papers in top journals including J. Math. Pures Appl. and Arch. Ration. Mech. Anal. Awards: Member of Institut Universitaire de France (2023-) Current activities: Organizer of international workshops on calculus of variations Supervises a postdoc position starting September 2024 Laboratory affiliation: Institut Elie Cartan de Lorraine (IECL), a CNRS-affiliated mathematics institute.
