Professor Markenscoff research interests lie in the dynamics and evolution of defects with inertia, including dislocation motion, expanding inclusions and inhomogeneities with transformation strain, moving phase boundaries, in which she has an extensive body of work. The energetics (driving forces) and the evolution of the moving defects are governed by Noether’s theorem of the calculus of variations in a variable domain, one of the important theorems of the 20th century. Recent results include the calculation of the dynamic Eshelby tensor for self-similarly expanding ellipsoidal inclusions, which preserve the constant stress property inside. For a solid containing a periodic distribution of defects, the energy dissipated in the unit cell is governed by the dynamic J, L, M integrals according to Noether’s theorem and by dynamic asymptotic homogenization is carried to the macro-scale as dynamic macroscopic damage. This new field can be called Dynamic Eshelby Micromechanics. Other research topics include theory of elasticity, incompatibility, the Cosserat spectrum, singular asymptotics, and a contribution to robotics. Her work is supported by the National Science Foundation.
Professor Markenscoff received her Diploma in Civil Engineering from the National Technical University of Athens, Greece, and her Ph.D. from Princeton University. She has been research Associate at MIT and Brown University, Assistant Professor at Carnegie-Mellon, and Associate and Full Professor at UCSB before joining UCSD. She was a Visiting Miller Professor at UC Berkeley in 2003 and a Russell Severance Springer Distinguished Visiting Professor in Mechanical Engineering at UC Berkeley in 2008.She is a Fellow of ASME and the Society of Engineering Science (SES).
