We study the chemical reactions which take place at the interface between a charged electrode and an electrolyte solution using scanning electrochemical and scanning photocurrent microscopies. We use these fundamental studies to help guide us to developing new measurement strategies and sensors. We are particularly interested in developing new chemical sensors based on semiconducting photoelectrodes, measuring nanoparticle collisions on semiconductor surfaces, and using scanning probe microscopies to better understand electron transfer reactions at the micro- and nanoscale.

Light addressable electrochemical sensors. We are working to develop chemical sensors for a variety of applications using semiconducting photoelectrodes. Semiconductors enable the electrochemical signal to be triggered with light, which helps us fabricate massive arrays of sensors and avoids cumbersome electronics.

3D-printing electrochemical devices. We are developing ready-to-use analytical devices using multi-material 3D-printing. We are developing new sensors for water-quality and disease diagnostics, and working on ways to widely distribute these sensors to the wider community.

Nanoparticle impacts. We are working to understand what happens when a nanoparticle in solution collides with an electrode in solution. We study these events at the single-entity level and hope to apply the knowledge to develop novel sensors for microplastics and biological targets.
