Research Interests

Interdisciplinary science

The key problems facing society today demand interdisciplinary solutions. Collaborating is easy, but building a tight and effective team across boundaries can be difficult. I specialize in working on teams with biologists, chemists, physicists, and engineers to leverage collective expertise and deliver timely insight on applied materials science problems.

Electrocatalysis

An in-depth, mechanistic understanding of many key electrochemical processes remains elusive, from batteries to solar cells to corrosion. Developing new experimental tools to investigate these complex reactions enables not only better life cycle management of current devices, but will enable the next-generation of clean power technologies and energy storage systems.

Spectromicroscopy

Composite materials and interfaces exhibit intrinsic spatial heterogeneity, and a complete understanding of these systems requires hybrid analytical approaches which combine imaging and conventional spectrometric tools. Challenging materials with both hard and soft matter components are a particular specialty.

Thin film deposition

Modern electronic devices require increasingly precise and robust thin films, which demand new techniques to controllably fabricate and characterize nanostructured 2D materials.
