Rodica Costin

Rodica Costin is a Professor in the Department of Mathematics at The Ohio State University, part of the College of Arts and Sciences. She holds a PhD from Rutgers University (1997). Her research focuses on differential and partial differential equations, asymptotic analysis, and orthogonal polynomials, with applications in mathematical physics and quantum systems.

Her work explores topics such as Hamiltonian systems, nonlinear dynamics, and time-dependent Schrödinger equations modeling photoemission and ionization processes. Recent research also addresses spherical harmonic expansions, Painlevé equations, and the convergence properties of series solutions in mathematical analysis.

Dr. Costin’s publications span over three decades, with notable contributions to exact and asymptotic solutions of quantum systems, spectral theory, and nonlinear differential equations. Her methodologies include rigorous WKB techniques, Hadamard finite-part integrals, and multiple orthogonal polynomials.

While no student advisees are listed in available records, her research has implications for condensed matter physics, laser-matter interactions, and celestial mechanics.
