Research

The understanding and control of materials properties has been pivotal in the development of modern technology. This scheme continues as we progress into the 21st century, and I contribute to the broad research effort as a Ph.D. student in the Materials Department at the University of California, Santa Barbara. I work in the Materials Research Laboratory where I am a member of Professor Ram Seshadri's research group. Our research is in the fields of Materials Science and Engineering, Solid State Chemistry, and Condensed Matter Physics. We focus on functional inorganic oxide materials because they exhibit a diverse array of phenomena that can be useful in engineering, such as superconductivity, negative thermal expansion, fluorescence, magnetism, and ferroelectricity. My project investigates multifunctional oxides for computing, sensing, and energy applications. I collaborate with the research groups of Professor Matthew J. Rosseinsky FRS at the University of Liverpool and Professor Anthony K. Cheetham FRS at the University of Cambridge.

Materials Science and Engineering

The field of Materials Science and Engineering aims to improve the properties of existing materials for today's technologies and develop new materials for the future. These materials are diverse, ranging from light-weight yet strong materials for energy-efficient airplanes, to biodegradable hip-replacement materials that enable complete healing, to computer materials responsible for the "Silicon Age." A confluence of Chemistry, Physics, Biology, and Engineering is necessary to bridge the gap between these seemingly dissimilar materials. Materials Science and Engineering recognizes universal relationships between materials synthesis, processing, elemental composition, chemical bonding, microstructure, properties, and performance. Control of the mechanisms behind these relationships is at the foundation of the field and enables materials to be designed for an application and tailored to specific requirements. Examples are discussed on the next page.
