MarÃa Varela Del Arco
Professor
Applied Physics
Complutense University of Madrid
Spain
Biography
"Maria Varela obtained her BS (1997) and PhD (2001) in Physics at the Complutense University, Madrid, Spain. She joined Oak Ridge National Laboratory as a Wigner Fellow in 2002 and has been a Research Staff Member in the Materials Science and Technology Division since 2004. In 2010 she also became a Professor at Complutense University of Madrid after being the recipient of an European Research Council Starting investigator Award. Her research experience includes thin film growth, transport properties and structural characterization by x ray diffraction and electron microscopy, specializing in aberration corrected scanning transmission electron microscopy and atomic resolution energy loss spectroscopy. "
Research Interest
Her main research interests include a variety of topics related to magnetism and complex oxide nanosystems, thin films and superlattices, including high Tc superconductors, colossal magnetoresistance materials, multiferroics, dilute magnetic semiconductors and other materials.
