Electrochemistry at Nanoscale

Our group has moved. Please visit our new website at to UT Austin.



We use electrochemistry and nanotechnology to address problems in energy and health.



The Ren Research Group

Welcome to the electrochemistry group at Miami University in Oxford, Ohio! We are interested in studying fundamental electrochemical energy storage and conversion processes at the nanoscale and single entity levels. We are also devoted to developing electrochemical systems for biomedical applications.
