Transformation of materials from one form into another has fascinated scientists over the centuries. Complex oxides, a class of ceramic materials possess electronic and magnetic properties that can be perturbed dramatically by subtle changes in crystal chemistry or external fields. I will discuss the topic of insulator-metal transitions in strongly correlated oxides, their control via disorder, orbital occupancy and electric fields and challenges these systems pose to our contemporary understanding of emergent phenomena in ionic lattices.


Shriram Ramanathan Shriram Ramanathan is a professor in materials at Purdue University. He received his Bachelor’s Degree in Metallurgical Engineering from the Indian Institute of Technology in India in 1996, his Master’s Degree in Materials Engineering from the University of Houston in 997, and his PhD in Materials Science and Engineering from Stanford University in 2002. In addition to serving as an Assistant Professor at Harvard University from 2006-­‐2010, he also served as Researcher/Senior Process Engineer in Components Research at Intel Corporation from 2002-­‐2005.

Dr. Ramanathan’s research focuses on thin film materials synthesis, electronic devices, and new materials for solid oxide fuel cells, and he has received numerousawards including National Academies Keck Futures Grant in 2014, after being named a Kavli Fellow Lecturer by the United States National Academy of Sciences in 2012. In 2011, he received the Robert Lansing Hardy Award from The Minerals, Metals and Materials Society (TMS), as well as the CAREER Award from National Science Foundation in 2010.
