Research Interests

My research focuses on the control of interfaces in electronic ceramics, particularly oxides. This work spans multiple material forms and applications: 1. Bulk Materials: Ferroelectrics: We concentrate on the manipulation and control of domain walls to optimize material properties. Thermoelectrics: Our research aims to enhance performance through precise interfacial control. 2. Supported Thin Films: Heterostructures: We investigate how heterointerfaces and surfaces can induce novel two-dimensional phenomena or modulate the properties of thin films. This includes work on ionic conductors and battery materials. 3. Free-Standing Thin Films: 2D Nanosheets: By employing top-down chemical exfoliation techniques, we create two-dimensional nanosheets from powders with layered structures. These nanosheets are primarily used to manipulate electronic behavior and for catalytic applications. In addition to experimental research, we apply data science tools to develop data-driven models, enhancing our understanding and prediction capabilities. A notable project in our lab is the creation of a new data engine for unpublished X-Ray Diffraction Data (CRUX).

Teaching Interests

Fall Semester Courses: 1) Mesoscale Structural Control of Functional Materials (EMSE 328/428): This course delves into the mesoscale structures of materials and their effects on electrical properties. We explore structures ranging from the electronic scale to the microstructure, examining how they influence and enable various functions. Students learn to understand the interrelationships between structures at different scales and how to tailor them for specific outcomes. The course integrates fundamental science with practical applications, demonstrating how structural control can modify and enhance material properties. In this class we integrate HoloLens to teach 3D symmetry in 3D. 2) Role of Materials in Energy and Sustainability (EMSE 349/449) This course is divided into two parts; (i) Engineered Materials as Consumers of Resources: We investigate the resource demands (raw materials, energy) associated with materials production, fabrication, and recycling. Topics include global energy usage, the availability of raw materials (including strategic materials), and factors influencing global reserves and annual production. (ii) Engineered Materials in Energy Efficiency and Sustainable Technologies: We explore the role of materials in energy-efficient technologies such as photovoltaics, solar thermal systems, fuel cells, wind turbines, batteries, and capacitors. Additionally, we cover materials used in energy-efficient lighting and discuss the concept of energy return on energy invested. The course emphasizes design strategies and the importance of incorporating environmental impacts into design criteria. Spring Semester Course: Chemistry of Materials (ENGR 145): A core engineering course, this class focuses on applying fundamental chemistry principles to understand materials. Emphasis is placed on the relationship between bonding, structure, and properties in metals, ceramics, polymers, and electronic materials. Students gain a deep understanding of how to synthesize materials by applying chemistry principles, with a focus on the connections between bonding and material properties.
