Dr. Chunmei Wang received her PhD in computational mathematics from the Nanjing Normal University in China in 2014. Dr. Wang’s research interests fall under the broad heading of numerical methods and scientific computing for problems in science and engineering governed by partial differential equations. Her research is interdisciplinary and addresses modeling and computation of applied problems in science and engineering. She has devised new finite element methods and established the corresponding convergence analysis for (1) linear hyperbolic equations, (2) elliptic Cauchy problems, (3) second order elliptic equations in nondivergence form, (4) Maxwell's equation, (5) linear elasticity and elastic interface problems, (6) div-curl systems, and (7) biharmonic equations.
