Elena Constantin

Elena Constantin, PhD, is a Professor in the Department of Mathematics at the University of Pittsburgh at Johnstown, within the Natural Sciences Division. Her academic background includes a BS and MS from Alexandru Ioan Cuza University in Romania, an MS from Ohio University, and a PhD from Ohio University (2005). Her research focuses on advanced optimization theory, including nonsmooth optimization, multiobjective optimization, and optimality conditions involving second-order tangent cones and variational principles.

Her work bridges pure and applied mathematics, with contributions to vector optimization, Lipschitz continuity analysis, and flow invariance in dynamical systems. Key themes in her publications include necessary and sufficient optimality conditions for constrained problems, particularly in degenerate and nonsmooth settings. She has also explored Green's functions in boundary value problems and critical cases in optimization via tangential cones.

No formal awards or grants are listed in the provided materials. Her advising records and lab affiliations remain unspecified. Her research trends emphasize rigorous mathematical analysis of optimization frameworks, with applications to both theoretical and applied problems in operations research and calculus of variations.
