Eva Andrei is an experimental condensed matter physicist recognized for her work on low dimensional electron systems, including two-dimensional electrons on helium, magnetically induced Wigner crystal in semiconductor heterojunctions and vortices in superconductors. She is known particularly for her ground-breaking work on the electronic properties of graphene - a one-atom thick membrane of crystalline carbon with extraordinary electronic properties stemming from charge carriers that behave like ultra-relativistic particles.
Following an undergraduate degree from Tel Aviv University Andrei received her Physics PhD from Rutgers University. In 1987 after post-doctoral work at Bell laboratories and Saclay France, she joined Rutgers as an assistant professor of Physics. She is currently a Board of Governors Chaired professor in the department of Physics and Astronomy at Rutgers University.

Current research Interests.
Andrei employs magneto-transport, scanning tunneling microscopy and spectroscopy to elucidate the electronic properties of graphene and other 2-dimensional materials, and how they are affected by external perturbations such as magnetic field, charge impurities, boundaries and substrate materials. She and her group demonstrated that by suspending graphene so as to leave it unattached to a substrate it is possible to access the intrinsic properties of its unusual charge carriers. This led to the observation of the fractional quantum Hall effect, providing a direct manifestation of unexpectedly strong electron- electron correlations in this material. In 2009, the AAAS journal Science cited these findings in its list of the year’s 10 groundbreaking scientific achievements. Another example is the discovery by Andrei and her group of so-called “Van Hove singularities” in the band structure of stacked graphene layers. They showed that by superposing graphene layers so that their relative crystal orientation is twisted away from equilibrium it is possible to change in a controlled way the band structure, a property which is usually considered to be intrinsic to the chemical composition and crystal structure of a material.
