Reactivity depends on the neighbourhood.
Real solid-state materials are disordered. The structure that governs how a material behaves is rarely the bulk structure that is readily measured. The important features that direct chemistry are smaller, messier, and localized. We develop strategies to find the defects, local distortions, and reaction mechanisms associated with this disorder, and use them to design targeted solutions.
Localized structures govern localized reactivity
Textbook solid-state chemistry describes ordered lattices. Materials with active interfaces, such as catalysts, functional coatings, electrodes, and sensor materials, are rarely so simple to describe. They contain disorder and defects, and often undergo complex interface-driven changes during operation. Such features are critical to establishing functionality, but are absent in clean structural models.
We develop measurement strategies to probe the disorder and defects hidden in materials, then apply chemical insights to modify structure and chemical reactivity. These efforts span electrified interfaces, gas-phase catalytic reactions, and all-solid-state reactions in industrial settings. In each of these areas, we are asking how localized structures and environments influence reactivity.
Research areas
Electrochemistry & Energy Conversion
Understanding the materials we use at electrified interfaces and the mechanisms by which they drive catalysis.
Read more 02Solid-State Reactivity & Catalysis
Studying reactions in and on solid materials to learn how to guide phase transformations and catalyst performance.
Read more 03Measurement & Analytical Science
Developing the experiments, instruments, and analysis needed to get structural information from difficult measurements.
Read moreTraining tailored to each student
Each graduate student’s program includes time working outside the group, chosen to fit their project: synchrotron beamtimes, instrumentation workshops, international research exchanges, or internships with industrial partners. These experiences build both technical skill and scientific judgement.
Engaging with the real world
A sizable share of our research is done in partnership with companies working to improve their existing technologies or develop new ones. Past projects include custom catalyst design, automotive parts manufacturing, and chemical sensor instrumentation. Working on industrial problems also shapes the direction of our fundamental research and the training our students receive.
