My research interests focus on understanding the structure—property relationships of inorganic solid state materials, particularly those of relevance to energy and electronics-related technology. Through understanding the arrangement of the atoms in a material, we can explain how atomic interactions give rise to various physical properties, such as how a material interacts with light or conducts electricity. I am particularly interested in utilizing advanced neutron and synchrotron X-ray scattering techniques to gain a detailed understanding of the structure of a material. Research in my laboratory focuses on solid state synthesis and characterization techniques with an emphasis on scattering experiments performed at national laboratories.

My teaching interests include cultivating an interactive environment that integrates active learning techniques with classic lecture styles to promote confidence, enthusiasm, and critical thinking. I am currently teaching Atomic and Molecular Structure (CHEM 107) and Inorganic Chemistry (CHEM 215). Other courses taught include Chemical Reactivity (CHEM 108), Advanced Topics in Inorganic Chemistry (CHEM 316), and Chemical Synthesis and Reactivity (CHEM s42).
